Answers

A bowling ball moving at 11 meters per second will have approximately 537.64 joules of energy, rounded to the nearest hundredth.

The kinetic energy (E) of a moving object varies directly with the square of its velocity (v). To write the equation relating E to v, we can use the formula: E = k * v^2, where k is a constant of proportionality. Given a bowling ball traveling at 15 meters per second with 1000 joules of energy, we can find the value of k:

1000 = k * (15^2)
1000 = k * 225
k ≈ 4.44

So, the equation relating the kinetic energy and velocity is: E ≈ 4.44 * v^2.

Now, we want to find the energy of the bowling ball when it's moving at 11 meters per second. Using the derived equation:

E ≈ 4.44 * (11^2)
E ≈ 4.44 * 121
E ≈ 537.64

Therefore, a bowling ball moving at 11 meters per second will have approximately 537.64 joules of energy, rounded to the nearest hundredth.

This gives us the reduction formula:

[tex]I_n = ∫cot^n x dx = cot^(n-1) x ln |sin x| - (n-1) I_(n-2).[/tex]

Using this formula, we can find I_4 as follows:

Consider the following. sin u = 3/5 π/2 (a) Determine the quadrant in which u/2 lies. O Quadrant 1 O Quadrant II O Quadrant III O Quadrant IV (b) Find the exact values of sin(u/2), cos(u/2), and tan(u/2 sin(u/2) cos(u/2) = tan(u/2) =

Answers

(a) The quadrant in which u/2 lies is either Quadrant I or Quadrant II.

(b) The exact values of sin(u/2), cos(u/2), and tan(u/2) are:
sin(u/2) = √10/5
cos(u/2) = 3√10/10
tan(u/2) = 2/3

(a) To determine the quadrant in which u/2 lies, we need to look at the value of sin u. Since sin u is positive (3/5 is positive and π/2 is in Quadrant I), we know that u is in either Quadrant I or Quadrant II.

To find u/2, we divide u by 2, which means u/2 will be in either Quadrant I or Quadrant II as well. Therefore, the answer is either Quadrant I or Quadrant II.

(b) We can use the half-angle formulas to find the values of sin(u/2), cos(u/2), and tan(u/2):

sin(u/2) = ±√[(1 - cos u)/2]
cos(u/2) = ±√[(1 + cos u)/2]
tan(u/2) = sin(u/2)/cos(u/2)

Since sin u = 3/5, we can find cos u using the identity sin^2 u + cos^2 u = 1:

cos u = ±√[(1 - sin^2 u)] = ±√[(1 - 9/25)] = ±4/5

Since u/2 is in either Quadrant I or Quadrant II, we know that sin(u/2) and cos(u/2) are positive. Therefore, we can choose the positive square roots for sin(u/2) and cos(u/2):

sin(u/2) = √[(1 - cos u)/2] = √[(1 - 4/5)/2] = √[1/10] = √10/10 = √10/5
cos(u/2) = √[(1 + cos u)/2] = √[(1 + 4/5)/2] = √[9/10] = 3/√10 = 3√10/10

Finally, we can use these values to find tan(u/2):

tan(u/2) = sin(u/2)/cos(u/2) = (√10/5)/(3√10/10) = 2/3

On a certain plaats moon the acceleration due to gravity is 2.9 m/sec^2 if a rock dropped into a chivaste, how fast it will be going just before it hits the bottom 31 secs later?

Answers

the rock will be going 89.9 m/s just before it hits the bottom of the chaste on a certain plaats moon.

To answer your question, we need to use the formula for the acceleration due to gravity, which is:

a = g

where a is the acceleration, and g is the gravitational constant. In this case, we know that the acceleration due to gravity on the moon is 2.9 m/sec^2, so we can substitute that into the formula:

a = 2.9 m/sec^2

Now we need to use the formula for calculating the speed of an object that is falling under the influence of gravity, which is:

v = gt

where v is the speed, g is the gravitational constant, and t is the time. We know that the rock takes 31 seconds to hit the bottom of the chivaste, so we can substitute that into the formula:

t = 31 s

Now we can calculate the speed of the rock just before it hits the bottom:

v = gt
v = 2.9 m/sec^2 x 31 s
v = 89.9 m/s

So the rock will be going 89.9 m/s just before it hits the bottom of the chivaste on the certain plaats moon.

Answers

Therefore, the measure of line segment XC is 3.75 cm.

What is perpendicular?

In geometry, two lines or planes are said to be perpendicular if they intersect each other at a right angle (90 degrees). The term "perpendicular" is also commonly used to describe the relationship between a line and a surface, where the line is at a right angle to the surface at the point of intersection. In general, the concept of perpendicularity is fundamental to many mathematical and scientific fields, such as trigonometry, physics, and engineering. It is also a commonly used term in everyday language to describe objects or structures that intersect at right angles, such as the corners of a square or the legs of a chair.

Here,

In the given diagram, let O be the center of the circle and let XC = a.

Since AB is perpendicular to XY at C, we have AC = BC = 8 m (using Pythagoras theorem). Also, since AB is a radius of the circle, we have AB = r, where r is the radius of the circle.

By the power of a point theorem, we have:

AC × XC = BC × XY

Substituting the given values, we get:

8 m × a = 8 m × 30 cm

Simplifying and converting units, we get:

a = 3.75 cm

If c(t) = 53.2te^{- 0.26} measures the concentration, in ng/ml of a drug in a person's system thours after the drug is administered. a) What is the peak concentration of the drug? b) When does the drug reach peak concentration?

Answers

(a) To find the peak concentration of the drug, we need to find the maximum value of c(t). Since c(t) is an exponential function, its maximum value occurs at its maximum point, which is where its derivative is equal to zero. We can find this point by taking the derivative of c(t) and setting it equal to zero:c'(t) = 53.2e^{-0.26} - 13.832te^{-0.26} = 0Solving for t, we get t = 3.870 hours. Therefore, the peak concentration of the drug is c(3.870) = 109.2 ng/ml.(b) To find when the drug reaches peak concentration, we have already found that it occurs at t = 3.870 hours.

The peak concentration of the drug is approximately 42.83 ng/ml, and it occurs around 3.85 hours after the drug is administered.

To find the peak concentration of the drug and when it reaches that peak, we'll need to consider the given function c(t) = 53.2te^(-0.26t), where t is the time in hours.

a) To find the peak concentration, we need to determine the maximum value of c(t). We can do this by taking the first derivative of c(t) with respect to t and setting it equal to 0.

c'(t) = 53.2(-0.26)e^(-0.26t) + 53.2e^(-0.26t) = 0

Now, solve for t:

t ≈ 3.85 hours

b) Plug the value of t back into the c(t) function to find the peak concentration:

c(3.85) = 53.2(3.85)e^(-0.26(3.85)) ≈ 42.83 ng/ml

So, the peak concentration of the drug is approximately 42.83 ng/ml, and it occurs around 3.85 hours after the drug is administered.

Answers

The answer is B) - (11x² - 6x)ln(3) + 2ln(3) - 6ln(x) + C, where C is the constant of integration.

To solve this problem, we are given a function h(x) and asked to find its antiderivative or indefinite integral, which is denoted by H(x) and is defined as the function whose derivative is h(x). We are also given a specific value of H(x) at x = 6 and asked to use it to find the constant of integration, denoted by C.

The given function is h(x) = 22x - 3x² - 6/x, and we want to find H(x), which is the antiderivative of h(x). Using the power rule of integration, we can integrate each term of h(x) separately:

∫ (22x - 3x² - 6/x) dx = ∫ 22x dx - ∫ 3x² dx - ∫ 6/x dx= 11x² - x³ - 6ln|x| + C

where C is the constant of integration. Note that we need to include an absolute value sign around x in the natural logarithm term because the function is not defined for x = 0.

Next, we are given that H(6) = 31, which means that when x = 6, the value of H(x) is 31. Substituting x = 6 and H(x) = 31 into the above equation, we get:

31 = 11(6)² - (6)³ - 6ln|6| + C

Simplifying, we get:

31 = 132 - 216 - 6ln(6) + CC = 221/3 - 6ln(6)

Therefore, the antiderivative of h(x) is:

H(x) = 11x² - x³ - 6ln|x| + 221/3 - 6ln(6)

We can simplify the expression by using the identity ln|a/b| = ln|a| - ln|b|:

H(x) = 11x² - x³ - 6ln(3) - 6ln(x) + 2ln(3) + C

where C is the constant of integration. Thus, the final answer is:

B) - (11x² - 6x)ln(3) + 2ln(3) - 6ln(x) + C, where C is the constant of integration.

The expedition team decides to have another practice run. Two team members head due north at a pace of 4 km/h. The second pair decide to head 60° west of north travelling at the same pace. How far from the first pair is the second pair after 2 h?

Answers

After the duration of 2 hours the distance between the first pair and the second pair is 3.07 km, under the condition that the second pair decide to head 60° west of north travelling at the same pace.

In order to evaluate the distance between two points with given coordinates, we can apply the distance formula. The distance formula is

d = √ [ (x₂ − x₁)² + (y₂ − y₁)² ]

Here,

(x₁, y₁) and (x₂, y₂) = coordinates of the two points.

For the given case, we can consider that the first pair of team members start at the origin (0, 0) and cover the distance towards  north for 2 hours at a pace of 4 km/h.

Hence, their final position is (0, 8).

The second pair of team members take  the origin (0, 0) and travel 60° west of north for 2 hours at a pace of 4 km/h.

Now to evaluate their final position, we have  to find their coordinates. Let us consider their final position (x, y).

We can apply trigonometry to find x and y.

The angle between their direction of travel and the y-axis is 60°.

sin(60°) = y / d

cos(60°) = x / d

Here,

d = distance travelled by the second pair of team members.

It is given that they travelled for 2 hours at a pace of 4 km/h.

d = 2 hours × 4 km/h

= 8 km

Staging this value into the above equations

y = d × sin(60°) = 8 km × sin(60°)

≈ 6.93 km

x = d × cos(60°) = 8 km × cos(60°)

≈ 4 km

Hence, the final position regarding the second pair of team members is approximately (4 km, 6.93 km).

Now we can apply the distance formula to evaluate the distance between the two pairs of team members

d = √ [ (x₂ − x₁)² + (y₂ − y₁)² ]

d = √ [ (4 − 0)² + (6.93 − 8)² ]

Answers

The area of the parallelogram is 8 units², which is option (b).

To find the area of a parallelogram, we need to use the formula A = bh, where A is the area, b is the base, and h is the height. In this case, we can use the distance formula to find the base and height.

Base = distance between points P and Q
= √[(5-3)² + (3-3)²]
= √4
= 2 units

Height = distance between point P and the line containing points R and S. We can find the equation of this line by first finding its slope:

slope = (y2 - y1)/(x2 - x1)
= (7 - 7)/(9 - 7)
= 0

Since the slope is 0, the line is horizontal and has an equation of y = 7. Therefore, the height is the distance between point P and this line, which is:

Height = distance from point P to line y = 7
= |3 - 7|
= 4 units

Now we can plug in the values of b and h into the formula A = bh:

A = 2 x 4
= 8 units²

if ф is an angle in quadrant iv, what is the value of tan(ф)?

Answers

The value of tan(ф) when cos(ф) = 8/9 in quadrant IV is - √17/8

To solve for the value of tan(ф), we need to use the trigonometric identity: tan(ф) = sin(ф)/cos(ф).

Since ф is in quadrant IV, we know that the cosine value is positive (due to cosine being positive in the adjacent side of quadrant IV) and the sine value is negative (due to sine being negative in the opposite side of quadrant IV).

We are given the value of the cosine, which is cos(ф) = 8/9. To find the sine, we can use the Pythagorean identity: sin²(ф) + cos²(ф) = 1.

Plugging in the given value of the cosine, we get: sin²(ф) + (8/9)² = 1. Solving for sin(ф), we get sin(ф) = - √(1 - (64/81)) = - √(17/81) = - √17/9.

Now that we have the values of sin(ф) and cos(ф), we can substitute them into the tan(ф) equation: tan(ф) = sin(ф)/cos(ф) = (- √17/9)/(8/9) = - √17/8.

Therefore, the value of tan(ф) when cos(ф) = 8/9 in quadrant IV is - √17/8.

If a polygon contains at least one more segment, it is a hexagon. It is a simple rectangle in shape. Anything like this can only be distinguished from a standard triangle form by edges A and B. Even if the edges are perfectly collinear, Euclidean geometry only creates a portion of the cube. A triangle is made up of a quadrilateral and three angles.

Here,

The lengths of all three sides must be added up in order to determine the jewellery's perimeter.

=> c²= a² + b²

where a and b are the lengths of the other two sides, and c is the length of the hypotenuse.

=> A = 3mm, and B = 4mm.

Therefore, we can determine the length of the hypotenuse using the Pythagorean theorem:

=> c² = a²+ b²

=> c² = 3² + 4²

=> c² = 9 + 16

=> c² = 25

=> c = √25)

=> c = 5 mm

As a result, the hypotenuse is 5 mm long.

We total the lengths of all three sides to determine the jewellery's perimeter:

=> perimeter = 4mm, 3mm, and 5mm.

=> 12 mm is the diameter.

Therefore, the jewellery's circumference is 12 mm.

The solution of the trigonometric equation

cos(2x) = cos(x) + 2

is x = 180°

How to solve the trigonometric equation?

Here we want to solve the equation:

cos(2x) = cos(x) + 2

First, we know that:

cos(2x) = 2cos(x)²  - 1

Then we can rewrite:

2cos(x)²  - 1 = cos(x) + 2

We can define:

cos(x)= y

2y² - 1 = y + 2

Then we need to solve the quadratic:

2y² - 1 - y - 2  =0

2y² - y - 3 = 0

Using the quadratic formula we will get:

[tex]y = \frac{1 \pm \sqrt{(-1)^2 - 4*2*2*-3} }{2*2} \\\\y = \frac{1 \pm 5}{4}[/tex]

so the solutions are:

y = (1 + 5)/4 = 6/4

y = (1-  5)/4 = -1

And remember that y = cos(x), then y =  6/4 can be discarded.

Then the solution comes from:

cos(x) = -1

then x = pi = 180°

Q4. A. A triangle has vertices (-2, 3), (1, 1) and (-1,-2).
a. Find the length of the sides. (3mks)
b. Name this triangle. (Imks)​

Answers

The length of the sides AB, BC and AC are √13, √13 and √26, hence the triangle is a isosceles triangle.

a. Points (-2, 3), (1, 1), (-1, 2) in the triangle are vertex. The distance formula for any two points is,

AB = √[(d-b)²+(c-a)²]

= √[(1 - (-2))² + (1 - 3)²]

= √[3² + (-2)²]

= √13

BC = √[(d-b)²+(c-a)²]

= √[(-1-1)²+(-2-1)²]

= √[(-2)² + (-3)²]

= √13

AC = √[(d-b)²+(c-a)²]

= √[(-1 - (-2))² + (-2 - 3)²]

= √[1² + (-5)²]

= √26

b. The triangle is an isosceles triangle because AB = BC.

What is an equation of the line that passes through the points ( 8 , 6 ) and ( − 3 , 6 )

Answers

The equation of line passing through the points (8, 6) and (-3, 6) is y = 6. Since the y-coordinate is the same for both points, the line is a horizontal line at y = 6.

To find the equation of the line passing through the points (8, 6) and (-3, 6), we can use the slope-intercept form of a linear equation:

y = mx + b

where m is the slope of the line and b is the y-intercept.

First, we need to find the slope, which is given by

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (8, 6) and (x2, y2) = (-3, 6)

m = (6 - 6) / (-3 - 8)

m = 0 / -11

m = 0

Since the slope is zero, the line is a horizontal line. We can see from the given points that the line passes through y = 6. Therefore, the equation of the line is

y = 6

2. If y is the time in years write an equation for the numbers of costumers c as a function of the numbers of years y after the introduction of the ordering system. ​

Answers

1. The growth factor for the number of customers over a year is approximately 1.4266.

2. the growth factor in customers over a decade period is approximately 5.927.

Factors that affect how many consumers there are in a year are

c(12)/c(0) = (400 x (1.03)¹²) / (400 x (1.03)⁰)

= (1.03)¹²

= 1.4266....

Therefore, the growth factor for the number of customers over a year is approximately 1.4266.

2. To write an equation for the number of customers c as a function of the number of years y, we can substitute m = 12y into the original equation

[tex]c(y) = 400 x (1.03)^{12y}[/tex]

one decade = 10 years

= 120 months

We must calculate the value of the equation at m=120 and divide it by the equation's value at m=0.

c(120) / c(0) = [400 x (1.03)¹²⁰] / [400 x (1.03)⁰]

= (1.03)¹²⁰

= 5.927...

Therefore, the growth factor in customers over a ten-year period is approximately 5.927.

Consider the following function f(x)=x^2+5


part a write a function in vertex form that shifts f(x) right 3 units


part b write a function in vertex form that shifts f(x) left 10 unites

Answers

Part a: f(x) = (x-3)^2 + 5

Part b: f(x) = (x+10)^2 + 5

Part a: To shift the function f(x) = x^2 + 5 right 3 units, we need to subtract 3 from the x-coordinate of the vertex. The vertex form of a quadratic function is given by f(x) = a(x-h)^2 + k, where (h,k) is the vertex. Thus, the function in vertex form that shifts f(x) right 3 units is:

f(x) = (x-3)^2 + 5

Part b: To shift the function f(x) = x^2 + 5 left 10 units, we need to add 10 to the x-coordinate of the vertex. Using the same vertex form as before, the function in vertex form that shifts f(x) left 10 units is:

f(x) = (x+10)^2 + 5

Answers

The probability of drawing a diamond or a spade card from a standard deck of cards and rolling a 2 on a six-sided die is 8.33%

To calculate the probability of drawing a diamond or a spade card from a standard deck of cards, we need to find the total number of diamond and spade cards in the deck. There are 13 cards in each suit, so there are 26 diamond and spade cards in total. The deck has 52 cards in total, so the probability of drawing a diamond or a spade card is:

P(diamond or spade) = 26/52 = 1/2 = 50%

To calculate the probability of rolling a 2 on a six-sided die, we need to find the total number of possible outcomes, which is 6 (since there are 6 sides on the die), and the number of favorable outcomes, which is 1 (since there is only one face with a 2 on it). Therefore, the probability of rolling a 2 on a six-sided die is:

P(rolling a 2) = 1/6 = 16.67%

To find the probability of both events happening together (drawing a diamond or a spade card and rolling a 2 on a six-sided die), we multiply the probabilities of each event:

P(diamond or spade AND rolling a 2) = P(diamond or spade) * P(rolling a 2)
= 50% * 16.67%
= 8.33%
