Help asap
If the first cube has a volume of 125 cm³ and the second cube has a volume of 343 cm³, the difference in the area of one face of the second cube and the area of one face of the first cube is 24cm². The answer is B. 24 cm².
To find the difference in the area of one face of each cube, we first need to find the side length of each cube. Since the volume of a cube is equal to the side length cubed (V = s³), we can find the side length by taking the cube root of the volume.
For the first cube:
Volume = 125 cm³
Side length = cube root of 125 = 5 cm
For the second cube:
Volume = 343 cm³
Side length = cube root of 343 = 7 cm
Next, we find the area of one face of each cube. The area of one face of a cube is equal to the side length squared (A = s²).
Area of one face of the first cube:
A1 = 5² = 25 cm²
Area of one face of the second cube:
A2 = 7² = 49 cm²
Finally, find the difference in the area of one face of each cube:
Difference = A2 - A1 = 49 cm² - 25 cm² = 24 cm²
The answer is B. 24 cm².

Express your answer numerically in seconds. View Available Hint(s) EVO AEO ? t = S Submit
Part a. The magnitude of the angular acceleration of the salad spinner as it slows down is 4.00 radians/s².
Part b. It takes 1.00 seconds for the salad spinner to come to rest.
Part A:
The initial angular velocity of the spinner is given by:
ω1 = 20.0 rotations / 5.00 s = 4.00 rotations/s
The final angular velocity of the spinner is zero.
The number of rotations between the initial and final angular velocities is:
Δθ = 6.00 rotations
Using the equation of motion for rotational kinematics with constant angular acceleration:
Δθ = 1/2 α t^2 + ω1 t
where α is the angular acceleration, and t is the time it takes to stop spinning.
At the final angular velocity, ω2 = 0, so we can rearrange the equation to solve for t:
t = ω1 / α
Substituting the given values:
Δθ = 6.00 rotations
ω1 = 4.00 rotations/s
t = (4.00 rotations/s) / α
Solving for α:
Δθ = 1/2 α t^2 + ω1 t
6.00 rotations = 1/2 α (t^2) + (4.00 rotations/s) t
Substituting t = (4.00 rotations/s) / α:
6.00 rotations = 1/2 α [(4.00 rotations/s) / α]^2 + (4.00 rotations/s) [(4.00 rotations/s) / α]
6.00 rotations = 8.00 rotations + 16.00 rotations/s^2 / α
α = 16.00 rotations/s^2 / (6.00 rotations - 8.00 rotations)
α = 8.00 rotations/s^2 / 2.00 rotations
α = 4.00 radians/s^2
Therefore, the magnitude of the angular acceleration of the salad spinner as it slows down is 4.00 radians/s^2.
Part B:
Using the equation of motion for rotational kinematics with constant angular acceleration:
ω2 = ω1 + α t
At the final angular velocity, ω2 = 0, so we can rearrange the equation to solve for t:
t = -ω1 / α
Substituting the given values:
ω1 = 4.00 rotations/s
α = 4.00 radians/s^2
t = -(4.00 rotations/s) / (4.00 radians/s^2)
t = -1.00 s
Since the time cannot be negative, we take the absolute value of t:
t = 1.00 s
Therefore, it takes 1.00 seconds for the salad spinner to come to rest.

The amount of money required to support a band field trip is directly proportional to the number of members attending the field trip and inversely
proportional with the fundraising money each member raised. If 100 members attend the field trip and each member raised $15. 00 through fundraising, the
field trip would cost $2,000. How much would the field trip cost if 150 members attend and each member raises the same amount through fundraising?
Cost of field trip remains $2,000 with 150 members
Field trip cost with 150 members?We can set up a proportion to solve for the cost trip with 150 members attending:
Let x be the cost of the field trip for 150 members attending.
The amount of money required is directly proportional to the number of members attending, so we can write:
[tex]100 : 150 = 2000 : x[/tex]
The amount of money required is also inversely proportional to the fundraising money each member raised. Each member raised $15.00 through fundraising, so we can write:
[tex]15 : 15 = x : 2000[/tex]
Simplifying the second proportion, we have:
[tex]1 : 1 = x/2000[/tex]
Multiplying both sides by 2000, we get:
[tex]x = 2000[/tex]
Therefore, the cost of the field trip with 150 members attending and each member raising $15.00 through fundraising would also be $2,000.

Write the number in standard form. (8 × 10) + (1 × 1/10 ) + (6 × 1/1000 )
We can simplify the given expression first and then write it in standard form.
8 × 10 = 80
1 × 1/10 = 1/10
6 × 1/1000 = 6/1000 = 3/500
Adding these three values, we get:
80 + 1/10 + 3/500
To write this in standard form, we need to express it as a single number multiplied by a power of 10. We can do this by finding a common denominator for the fractions and adding them:
80 + 50/500 + 3/500 = 80 + 53/500
Now, we can write this as:
80.106
To express this in standard form, we move the decimal point to the left until there is only one non-zero digit to the left of the decimal point. We moved the decimal point 3 places to the left to get:
8.0106 × 10^1
Therefore, the number in standard form is 8.0106 × 10^1.

polly works in a zoo and needs to build pens where animals can live and be safe. the walls of the pens are made out of cubes that are connected together. polly has 40 cubes and wants to make the largest pen possible, so the animals can move around freely but not get loose. build the largest area using all 40 cubes. your walls must:
• be fully enclosed, no doors or windows so polly’s animals can’t get out.
• have a height of one cube.
• each cube must be joined cube face to cube face.
help polly by making several shaped pens and determine what pen provides the largest area for the animals. you might want to build the pen on the grid paper first, so that it will be easier to determine the area.
use the grid paper to show the shape of the pen. explain to polly why you believe your pen is the largest one that can be made.
The rectangular pen with dimensions 5 x 6 x 2 is the largest pen that can be made using all 40 cubes.
To maximize the area of the pen, we need to create a rectangular shape. We can use all 40 cubes to create a rectangular pen with dimensions 5 x 6 x 2.
To build the pen, we can use 10 cubes for the base layer, then add 15 cubes for the second layer, and finally add 15 cubes for the third layer, creating a total of 40 cubes.
The base layer will be a rectangle with dimensions 5 x 6, and we will use 10 cubes to create it. Then we can stack two more layers of cubes on top of the base layer, each layer will have dimensions 5 x 6 and will use 15 cubes.
To prove that this pen has the largest area that can be made with 40 cubes, we can compare it with other possible shapes. For example, if we try to create a cube-shaped pen, we would only be able to create a cube with side length 3, which would have a volume of 27 and therefore could not use all 40 cubes.
Therefore, the rectangular pen with dimensions 5 x 6 x 2 is the largest pen that can be made using all 40 cubes.

C(x) - 1700 + 5x + 0.08x² + 0.0004x³. (a) Find the marginal cost function (b) Find C'(100) C'(100) What does this predict? The exact cost of the 101st pair of jeans The exact cost of the 100th pair of jeans The approximate cost of the 100th pair of jeans The approximate cost of the 101st pair of jeans The exact cast of the 99th pair of jeans. (c) Find the difference between C'(100) and the actual cost of manufacturing the 101st pair of jeans (Round your answer to two decimal places)
(a) The marginal cost function is C'(x) = 5 + 0.16x + 0.0012x².
(b) C'(100) = 21.00. This predicts the approximate cost of the 101st pair of jeans.
(c) The difference between C'(100) and the actual cost of manufacturing the 101st pair of jeans is $20.51.
(a) To find the marginal cost function, we need to take the derivative of the cost function C(x) with respect to x:
C'(x) = 5 + 0.16x + 0.0012x²
(b) To find C'(100), we substitute x = 100 into the marginal cost function:
C'(100) = 5 + 0.16(100) + 0.0012(100)²
C'(100) = 21.00
This predicts the approximate cost of the 101st pair of jeans, as the marginal cost function tells us the cost of producing one additional unit (pair of jeans) at a given quantity. So, we can use C'(100) to estimate the cost of producing the 101st pair of jeans.
To find the approximate cost of the 100th pair of jeans, we can substitute x = 100 into the cost function C(x):
C(100) = -1700 + 5(100) + 0.08(100)² + 0.0004(100)³
C(100) = $2330
So, the approximate cost of the 100th pair of jeans is $2330.
To find the approximate cost of the 101st pair of jeans, we can add C'(100) to the cost of producing 100 pairs of jeans:
C(100) + C'(100) = $2330 + $21.00
C(101) ≈ $2351
So, the approximate cost of the 101st pair of jeans is $2351.
To find the exact cost of the 99th pair of jeans, we can substitute x = 99 into the cost function C(x):
C(99) = -1700 + 5(99) + 0.08(99)² + 0.0004(99)³
C(99) = $2288.44
So, the exact cost of the 99th pair of jeans is $2288.44.
(c) To find the difference between C'(100) and the actual cost of manufacturing the 101st pair of jeans, we need to subtract the cost of producing 100 pairs of jeans from the cost of producing 101 pairs of jeans:
C(101) - C(100) = [-1700 + 5(101) + 0.08(101)² + 0.0004(101)³] - [-1700 + 5(100) + 0.08(100)² + 0.0004(100)³]
C(101) - C(100) = $20.51
So, the difference between C'(100) and the actual cost of manufacturing the 101st pair of jeans is $20.51.

Answer:
135.6 cubic centimeters
Step-by-step explanation:
To find the volume of soda in the cylindrical glass, we need to first find the volume of the glass and then multiply it by 60% to get the volume of soda. The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = π(3 cm)^2(8 cm) = 72π cm^3
To find the volume of soda, we multiply the volume of the glass by 60% or 0.6:
Volume of soda = 0.6 x 72π cm^3 = 43.2π cm^3
Rounding to the nearest tenth, we get:
Volume of soda ≈ 135.6 cm^3
Therefore, there are approximately 135.7 cubic centimeters of soda in the glass
Answer: 226.3
Step-by-step explanation:
Hello! Here is how to solve this problem.
The formula for volume of a cylinder is V(c) = (B)(h)
The height is 8 cm, and the radius is 3 cm. The base is a circle, so the base area will be 22/7(r)^2. Pi is represented as 3.14 or 22/7, but 22/7 is more accurate.
V(c) = 22/7((3)^2)(8)
V(c) = 22/7(9 x 8)
V(c) = 22/7(72)
V(c) = 226.285714.
So, rounded to the nearest tenth, the volume of the soda can is 226.3 cm^3.
Tips for you:
1. Round to the nearest tenth
2. Use 22/7 for pi unless it says to use 3.14 for pi or use the symbol for pi instead of solving further.

d12 = b1a2 + b2a4
d21 = b3a1 + b4a3
d22 = b3a2 + b4a4
To find the product of d, we need to find the values of b and a such that d11 = d12 = d21 = d22.
Let's assume that d11 = d12 = d21 = d22 = x. Then, we have:
b1a1 + b2a3 = x
b1a2 + b2a4 = x
b3a1 + b4a3 = x
b3a2 + b4a4 = x
We can solve for b1, b2, b3, and b4 in terms of a1, a2, a3, and a4:
b1 = (x - b2a3)/a1
b2 = (x - b1a1)/a3
b3 = (x - b4a3)/a1
b4 = (x - b3a1)/a3
Substituting these values of b1, b2, b3, and b4 into the equation d = ba, we get:
d11 = x = a1(x - b1a3)/a1 + a3(x - b2a1)/a3
= x - b1a3 + x - b2a1
= 2x - (b1a3 + b2a1)

Consider the following function
f(x) = x^2/x^2 -9
Find the criticat number of renter your antwers as a comma-separated list) Find the open intervals on which the function is increasing or decreasing. (Enter your answers using interval notation. If an answer does not exist, enter DNE.)
Critical numbers: 0, -3, 3
Increasing intervals: (-∞, -3), (3, ∞)
Decreasing intervals: (-3, 0), (0, 3)
Let's analyze the given function and find the critical numbers, as well as the intervals where it is increasing or decreasing.
Function: f(x) = x^2 / (x^2 - 9)
1. Find the critical numbers:
To find the critical numbers, we need to compute the first derivative of the function and set it equal to zero or identify where it's undefined.
f'(x) = (2x(x^2 - 9) - x^2(2x)) / (x^2 - 9)^2 = (2x^3 - 18x - 2x^3) / (x^2 - 9)^2 = -18x / (x^2 - 9)^2
Setting f'(x) equal to zero:
-18x = 0
x = 0
Now, let's check where f'(x) is undefined:
x^2 - 9 = 0
x = ±3
Thus, the critical numbers are 0, -3, and 3.
2. Find the open intervals where the function is increasing or decreasing:
To determine the intervals, we will examine the sign of f'(x) in the intervals determined by the critical numbers: (-∞, -3), (-3, 0), (0, 3), (3, ∞).
Interval (-∞, -3): Choose x = -4, then f'(-4) > 0. So, f(x) is increasing on this interval.
Interval (-3, 0): Choose x = -1, then f'(-1) < 0. So, f(x) is decreasing on this interval.
Interval (0, 3): Choose x = 1, then f'(1) < 0. So, f(x) is decreasing on this interval.
Interval (3, ∞): Choose x = 4, then f'(4) > 0. So, f(x) is increasing on this interval.
Your answer:
Critical numbers: 0, -3, 3
Increasing intervals: (-∞, -3), (3, ∞)
Decreasing intervals: (-3, 0), (0, 3)

Chris works at a book story she earn $7. 50 per h hour plus a $2 bonus for each book she sells chris sood 15 books she want to earn the minimum of $300 which Inequality represents the situation in what quantities are true for h
Chris must work at least 36 hours to earn a minimum of $300, assuming she sells 15 books and earns the $2 bonus for each book sold.
The inequality that represents the situation is: 7.50h + 2(15) ≥ 300 where "h" represents the number of hours Chris works, and "2(15)" represents the bonus earned for selling 15 books.
The left-hand side of the inequality calculates Chris's total earnings, which is the product of her hourly wage of $7.50 and the number of hours worked, plus the bonus earned for selling 15 books.
The inequality states that the total earnings must be greater than or equal to $300, which is the minimum amount Chris wants to earn. To solve the inequality, we can simplify it by first multiplying 2 and 15 to get 30: 7.50h + 30 ≥ 300
We can isolate "h" by subtracting 30 from both sides: 7.50h ≥ 270. we can solve for "h" by dividing both sides by 7.50: h ≥ 36.

(c) What do the answers to Parts 2(a) and 2(b) tell you about Adam’s and Miguel’s training times?
(a) Miguel had the greatest spread in training times.
(b) Adam had the least spread in the middle 50% of training times.
(c) Miguel's training times had a greater range, indicating more variability, while Adam's training times were more consistent and tightly grouped.
(a) Who had the greatest spread?(b) Who had the least spread?(c) how do the answers indicate?(a) To determine which person had the greatest spread, we need to compare the range or variability of their training times. By observing the given data, we can see that Adam's training times range from 92 to 106, resulting in a spread of 14. On the other hand, Miguel's training times range from 85 to 105, resulting in a spread of 20. Therefore, Miguel had the greatest spread of training times.
(b) To determine which person had the least spread in the middle 50% of training times, we need to compare the interquartile range (IQR). By calculating the IQR, we find that Adam's IQR is 9 (from the 25th to the 75th percentile), whereas Miguel's IQR is 7. Since Adam's IQR is greater, it means Miguel had the least spread in the middle 50% of training times.
(c) The answers to parts (a) and (b) indicate that while Miguel had a greater spread of training times overall, Adam's training times had a greater spread in the middle 50%. This suggests that Adam's training times were more concentrated around the median, while Miguel's training times were more spread out.

a) All of the training times of Adam had the greatest spread.
(b) The middle 50% of the training times of Adam had the least spread.
(c) The answers to Parts (a) and (b) tell us that Adam's training performance may be more stable within that middle 50%, while Miguel's performance is more variable.
(a) Adam's training times had the greatest spread.
To determine this, we can calculate the range of the data sets. For Adam, the range is 106-92 = 14 seconds, while for Miguel, the range is 105-85 = 20 seconds. However, a better measure of spread is the interquartile range (IQR), which focuses on the middle 50% of the data. For Adam, the IQR is 101-97 = 4 seconds, while for Miguel, the IQR is 96-89 = 7 seconds. In both cases, Miguel's data has a greater spread.
(b) Adam's training times had the least spread for the middle 50% of the data. This is demonstrated by the IQR, as mentioned above. For Adam, the IQR is 4 seconds, while for Miguel, it is 7 seconds.
(c) The answers to Parts 2(a) and 2(b) tell us that while Miguel's overall training times have a greater spread, the middle 50% of Adam's training times are more consistent, with less variation. This suggests that Adam's training performance may be more stable within that middle 50%, while Miguel's performance is more variable.

On a coordinate plane, a line segment has endpoints P(6,2) and Q(3. 8). 9. Point M lies on PQ and divides the segment so that the ratio of PM-MQ is 2-3. What are the coordinates of point M?
The coordinates of point M are:
Coordinates of M = (4.5 + sqrt(34)/5, 5)
Coordinates of M = (5.86, 5)
To find the coordinates of point M, we first need to find the coordinates of the midpoint of segment PQ.
The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is ((x1 + x2)/2, (y1 + y2)/2).
Using this formula, we can find the midpoint of PQ as follows:
Midpoint = ((6 + 3)/2, (2 + 8)/2)
Midpoint = (4.5, 5)
Now we can use the fact that PM/MQ = 2/3 to find the coordinates of point M.
Let's start by finding the distance between P and the midpoint:
Distance between P and midpoint = sqrt((4.5 - 6)^2 + (5 - 2)^2)
Distance between P and midpoint = sqrt(4.25)
Since PM/MQ = 2/3, we know that PM is 2/5 of the total distance between P and Q, and MQ is 3/5 of the total distance.
Let's call the total distance between P and Q "d". Then we have:
PM = (2/5)d
MQ = (3/5)d
We can use these expressions to find the distance between M and the midpoint:
Distance between M and midpoint = PM - MQ
Distance between M and midpoint = (2/5)d - (3/5)d
Distance between M and midpoint = -(1/5)d
Finally, we can use the distance formula to find the coordinates of point M:
Coordinates of M = (4.5, 5) + (Distance between M and midpoint in the x direction, Distance between M and midpoint in the y direction)
In other words, the x-coordinate of M is 4.5 plus the distance between M and the midpoint in the x direction, and the y-coordinate of M is 5 plus the distance between M and the midpoint in the y direction.
We already know that the distance between M and the midpoint in the y direction is 0 (since M lies on the same horizontal line as the midpoint), so we only need to find the distance between M and the midpoint in the x direction:
Distance between M and midpoint in the x direction = sqrt((1/5)d^2)
Since d is just the distance between P and Q, we can find it using the distance formula:
d = sqrt((6 - 3)^2 + (2 - 8)^2)
d = sqrt(34)
So we have:
Distance between M and midpoint in the x direction = sqrt((1/5)(sqrt(34))^2)
Distance between M and midpoint in the x direction = sqrt(34)/5

Ignacio chooses a plant at random that does not have a white bloom. What is the probability of the complement of the event? Express your answer as a fraction in simplest form
The probability of the complement of the event of Ignacio chooses a plant at random that does not have a white bloom is 0.7692.
The probability of an occurrence is a figure that represents how likely it is that the event will take place. In terms of percentage notation, it is stated as a number between 0 and 1, or between 0% and 100%. The higher the likelihood, the more probable it is that the event will take place.
Probability is a way to gauge how likely something is to happen. Several things are difficult to forecast with absolute confidence. With it, we can only make predictions about the likelihood of an event happening, or how likely it is.
The probability that Ignacio chooses the plant which have white bloom in it is,
P = number of white bloom / total number of flowers
P = 21 / 91
So the probability that the chosen flower is not white is,
1 - P = 1 - 21/91 = 70/91 = 0.7692.
Therefore, the probability of not choosing white is 0.7692.

1_.the quadratic should have an exponent of which: 1,2 , or 3?
2_.the parabola ending its life going down should have a leading coefficient sign of positive or negative?
3._which would be the correct equation: y=x^2 or y=-x^2?
A quadratic function should have an exponent of 2, a parabola ending its life by going down should have a leading coefficient sign of negative, and either y = x^2 or y = -x^2 can be a valid equation for a quadratic function, with the choice depending on the direction of the desired parabola.
1. The quadratic should have an exponent of 2, as a quadratic is a polynomial of degree 2.
2. A parabola ending its life by going down should have a leading coefficient sign of negative, as this indicates that the quadratic term has a negative coefficient and the parabola opens downwards.
3. Both equations, y = x^2 and y = -x^2, are valid equations for a quadratic function. The main difference between them is the direction in which the parabola opens. The equation y = x^2 represents a parabola that opens upwards, while y = -x^2 represents a parabola that opens downwards. The choice of which equation to use depends on the specific context and the direction of the desired parabola.

1. A curve C in R3 is given by x = {3 – 1, y = -3t2 + 2, z = 8t – 2. Find parametric equations for the tangent line to C at P = (0, -1,6).
The parametric equations for the tangent line to curve C at point P are: x = -t y = 6t - 1 z = 8t + 6
To find the parametric equations for the tangent line to curve C at point P, we need to first find the derivative of the curve at P.
Taking the derivative of each component of the curve, we get:
dx/dt = -1
dy/dt = -6t
dz/dt = 8
At point P = (0, -1, 6), t = -1.
Plugging this into the derivative, we get:
dx/dt = -1
dy/dt = 6
dz/dt = 8
So, the tangent vector to curve C at point P is < -1, 6, 8 >.
To get the parametric equations for the tangent line, we can use the point-slope form: r(t) = P + t< -1, 6, 8 > Plugging in the coordinates of point P, we get: r(t) = <0, -1, 6> + t< -1, 6, 8 > Expanding this out, we get: r(t) = <-t, 6t - 1, 8t + 6>
