Answer: No, 2^7 is not equal to 2x7.
2^7 means 2 raised to the power of 7, which is 2 multiplied by itself 7 times:
2^7 = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
On the other hand, 2x7 means 2 multiplied by 7:
2x7 = 2 x 7 = 14
So 2^7 is not equal to 2x7.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
See, 2 ^ 7 is 2 TO THE POWER OF 7, which is repeated multiplication.
2 x 7 is 2 MULTIPLIED BY 7
2 ^ 7 written out completely is:
2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
See the repeated multiplication above?
2 x 7 is just 14.
See the difference!
14 is NOT equal to 128

Which ordered pair is a solution of y = x + 12?
A.( 24, 12)
B. (–12, –24)
C.( 9, 21)
D. (0, –12)
(9,21) is a solution of y=x+12
Step-by-step explanation:When is an ordered pair a solution?
To find if an ordered pair (x,y) is a solution to an equation, substitute the x-value and y-value from the ordered pair into the equation, evaluate both sides of the equation individually, and see if the equation is true.
If the two sides are equal, the ordered pair is a solution.If the two sides are not equal, the ordered pair is not a solution.Warning: A common mistake is to use the first coordinate (the x-coordinate, on the left of the ordered pair) as the value on the left side of the equation, and the second coordinate (the y-coordinate, on the right of the ordered pair), as the value for the right side of the equation. Make sure to substitute the x-value for the "x" in the equation, and the y-value for the "y" in the equation.
Going through the choices:
Point A (24,12)
y = x+12
(12) ?? (24) + 12
12 ≠ 36
not equal -- not a solution
Point B (-12,-24)
y = x+12
(-24) ?? (-12) + 12
-24 ≠ 0
not equal -- not a solution
Point C (9,21)
y = x+12
(21) ?? (9) + 12
21 = 21
equal -- (9,21) is a solution
Point D (0,-12)
y = x+12
(-12) ?? (0) + 12
-12 ≠ 12
not equal -- not a solution

Which of the following explains why this inequality is true?
7 3/8 × 4/5 < 7 3/8
Answer:
Step-by-step explanation:
To compare these two values, we first need to convert the mixed number 7 3/8 to an improper fraction. To do so, we multiply the whole number (7) by the denominator of the fraction (8), then add the numerator (3), and put the result over the denominator:
7 3/8 = (7 x 8 + 3) / 8 = 59/8
Now we can rewrite the inequality as:
(59/8) × (4/5) < 59/8
To simplify the left-hand side of the inequality, we multiply the numerators and denominators:
(59/8) × (4/5) = (59 × 4) / (8 × 5) = 236/40 = 59/10
So the inequality becomes:
59/10 < 59/8
To compare these fractions, we need to find a common denominator. The least common multiple of 8 and 10 is 40, so we can convert both fractions to have a denominator of 40:
59/10 = (59 x 4) / (10 x 4) = 236/40
59/8 = (59 x 5) / (8 x 5) = 295/40
Now we can see that 236/40 < 295/40, which means that:
59/10 < 59/8
Therefore, the inequality 7 3/8 × 4/5 < 7 3/8 is true.

Answer: 108
Step-by-step explanation:
If you turn the shape, where the pointy side of the ramp is facing you and you flipped it open and laid out the sides, that's the "net" image on right
A = 5 the long side of that triangle is also the short side of that rectangle
B = 3 it's the short side of the triangle
C = 8 long part of the rectangle
D = 4 long side of triangle
To find surface area. Find the area of each of the shapes and add it all up
Top Rectangle:
A=Lw=C*A = 5*8 = 40
Middle Rectangle:
A=Lw = B*C = 3*8 = 24
Bottom Rectangle:
A=LW = 4*C = 4*8=32
Triangles are same
A=1/2 bh = 1/2 D*B = 1/2 * 4* 3 =6
But there are 2 of them so A=12
Now add all the shapes together
A(total)=40+24+32+12=108

Answer:
circle graph titled New York City visitor's transportation, with five sections labeled walk 40 percent, bicycle 8 percent, car service 15 percent, bus 10 percent, and subway 27 percent.
Step-by-step explanation:
To find the correct percentages, we need to calculate the percentage of visitors who used each mode of transportation out of the total number of visitors, which is the sum of all the numbers in the table:
Total number of visitors = 120 + 24 + 45 + 30 + 81 = 300
Percentage of visitors who walked = (120 / 300) x 100% = 40%
Percentage of visitors who used a bicycle = (24 / 300) x 100% = 8%
Percentage of visitors who used a car service = (45 / 300) x 100% = 15%
Percentage of visitors who used a bus = (30 / 300) x 100% = 10%
Percentage of visitors who used the subway = (81 / 300) x 100% = 27%
Therefore, the circle graph that correctly represents the data in the table is:

The best-fit linear regression equation gives us the equation y = 0.0804x + 1.1794, where the slope is 0.0804 and the y-intercept is 1.1794.
The trendline equation will give us the equation for the linear regression line, which can be written in the form of y = mx + b, where m is the slope and b is the y-intercept.
Once we have the trendline equation, we can use it to make predictions about future enrollment percentages based on the number of years after 1820.
The slope of the line tells us the rate at which the enrollment percentage is increasing or decreasing over time, and the y-intercept tells us the enrollment percentage when x is equal to zero (i.e., in 1820).
Here we have find that the best-fit linear regression equation gives us the equation

Brent starts with 16 identical white socks in his sock drawer. Imagine he receives 2 identical black socks as a gift and mixes them in with his 16 white socks. If he draws one sock without looking to put on his left foot, then draws a second sock without looking to put on his right foot, what is the probability that he draws mismatched socks?
The probability that Brent draws mismatched socks is approximately 31/153.
After adding 2 identical black socks, Brent has a total of 18 socks in his drawer. The probability of drawing a white sock on the first draw is 16/18 (since there are 16 white socks out of 18 total socks).
After drawing a white sock on the first draw, there are 15 white socks and 2 black socks left in the drawer. The probability of drawing a black sock on the second draw is 2/17 (since there are 2 black socks out of 17 total socks left). So the probability of drawing a white sock followed by a black sock is;
(16/18) × (2/17) = 32/306
Similarly, the probability of drawing a black sock followed by a white sock is;
(2/18) × (15/17) = 30/306
However, the probability of drawing mismatched socks is;
32/306 + 30/306 = 62/306
= 31/153
Therefore, the probability will be 31/153.

write a situation that matches this inequality 8x+14<100
Suppose you are a small business owner who sells handmade crafts. You have a budget of $100 to purchase materials for your next batch of products. You know that each craft requires some amount of materials, which costs $8 per unit. Additionally, you will need to pay a fixed cost of $14 for other expenses related to production and shipping.
How the situation matches inequality 8x+14<100 ?To make a profit, you must ensure that the cost of materials and fixed expenses does not exceed the $100 budget. Therefore, you can write an inequality to represent this situation:
8x + 14 < 100
Here, x represents the number of units of materials needed for each craft. The inequality states that the total cost of materials (8x) plus fixed expenses ($14) must be less than $100.
To solve this inequality, you can subtract 14 from both sides:
8x < 86
Finally, you can divide both sides by 8:
x < 10.75
This means that for each craft, you can use no more than 10.75 units of materials in order to stay within budget and make a profit.

Ina Crespo rowed 16 miles down the Habashabee River in 2 hours, but the return trip took her 4 hours. Find the rate Ina rows in still water and the rate of the current. Let x represent the rate Ina can row in still water and let y represent the rate of the current.
Ina rows at a rate of 6 mph in still water, and the current flows at a rate of 2 mph.
What is distance?Distance is the overall length of a journey that a person, item, or vehicle takes to get from one place to another. Due to its scalar nature, it has simply magnitude and no direction. Typically, distance is expressed in terms of metres, kilometres, miles, or feet. It is distinct from displacement, which describes the shift in an object's location from its starting point to its ending point while also taking the movement's direction into consideration.
According to given information:We can start by using the formula:
distance = rate × time
Let's first consider the trip downstream. In this case, Ina's speed relative to the river current adds up to the distance traveled per unit of time. So we have:
16 = (x + y) × 2
Simplifying and solving for x + y, we get:
x + y = 8
Now let's consider the trip upstream. In this case, Ina's speed relative to the river current subtracts from the distance traveled per unit of time. So we have:
16 = (x - y) × 4
Simplifying and solving for x - y, we get:
x - y = 4
We now have two equations with two variables, so we can solve for x and y using either substitution or elimination. Let's use elimination:
(x + y) + (x - y) = 8 + 4
2x = 12
x = 6
Now we can substitute x = 6 into either of the original equations to solve for y. Let's use the first equation:
x + y = 8
6 + y = 8
y = 2
Therefore, Ina rows at a rate of 6 mph in still water, and the current flows at a rate of 2 mph.

The solutions to f(x) = 0 on the interval [0, 2pi) are x = 0 and x = pi.
Understanding Trigonometric Function(a) For f(x) = 0
We set the function equal to zero and solve for x:
f(0) = sec²x - 1 = 0
sec² x = 1
Taking the square root of both sides, we get:
sec x = ±1
Recall that sec x = 1/cos x = cos⁻¹ x
Therefore
x = cos⁻¹ (1) = 0 (using calculator or table)
x = cos⁻¹(-1) = pi
Therefore, the solutions to f(x) = 0 on the interval [0, 2pi) are x = 0 and x = pi.
(b) For f(x) > 0
To get the positive values of x, we can start by factoring f(x):
f(x) = sec²x - 1 = (sec x + 1)(sec x - 1)
Since the square of the secant function is always positive, we have:
f(x) > 0 if and only if (sec x + 1)(sec x - 1) > 0
There are two cases to consider:
sec x + 1 > 0 and sec x - 1 > 0
sec x + 1 < 0 and sec x - 1 < 0
For case 1, we have:
sec x > -1 and sec x > 1
Since secant is always positive, we have sec x > 1.
For case 2, we have:
sec x < -1 and sec x < 1 (This is not possible)
(c) For f(x) < 0
By using the factored form of f(x) from part (b), we can find the values of x where f(x) is negative.
f(x) < 0 if and only if (sec x + 1)(sec x - 1) < 0
There are two cases to consider:
sec x + 1 > 0 and sec x - 1 < 0
sec x + 1 < 0 and sec x - 1 > 0
For case 1, we have:
sec x > 1 and sec x < -1 (not possible)
For case 2, we have:
sec x < -1 and sec x > 1
Since secant is always positive, this case is not possible either.
Therefore, there are no solutions to f(x) < 0 over the interval [0, 2pi).

Find the perimeter of each figure
The hexagon with sides of length 5 inches, 4 inches, 4 inches, 5 inches, 3 inches, and 3 inches has a perimeter of 24 inches.
What is a hexagon?A hexagon is a regular polygon, meaning all sides and angles are equal in size. It is a symmetrical shape, which means it can be divided into two equal halves.
To calculate the perimeter of this hexagon, we must first identify the length of each side.
All sides of the hexagon have a length of either 5 inches, 4 inches, or 3 inches, as there are two sides of each length.
The perimeter of the hexagon is the sum of the length of all its sides. Adding the length of all the sides, we get
5 + 4 + 4 + 5 + 3 + 3 = 24.
Thus, the perimeter of the hexagon is 24 inches.
Hence, the sum of the length of the sides of a hexagon is always greater than the length of any one of its sides.

The total cost for the first 25 units is given as follows:
$140.
How to obtain the total cost?The marginal cost function is defined as follows:
[tex]c(x) = \frac{14}{\sqrt{x}} = 14x^{-\frac{1}{2}}[/tex]
The total cost function is the integral of the marginal cost function, hence it is given as follows:
[tex]t(x) = \int c(x) dx[/tex]
[tex]t(x) = 28\sqrt{x}[/tex]
Applying the Fundamental Theorem of Calculus, the total cost from x = 0 to x = 25 is given as follows:
t(25) - t(0).
Thus:
t(25) = 28 x 5 = 140.t(0) = 28 x 0 = 0.Hence:
140 - 0 = $140.
(Applying the Fundamental Theorem of Calculus, we subtract the numeric values at each endpoint of the integral).

A function whose graph is the graph of y = √x, but is shifted to the left 9 units is [tex]y=\sqrt{x+9}[/tex].
What is a translation?In Mathematics and Geometry, the translation of a geometric figure or graph to the left means subtracting a digit from the value on the x-coordinate of the pre-image;
g(x) = f(x + N)
Conversely, the translation a geometric figure upward means adding a digit to the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) + N.
Based on the information provided, the transformed function should be written as follows:
y = √x
g(x) = (√x + 9)
[tex]y=\sqrt{x+9}[/tex]

Michael purchased stereo equipment for $2500. His wife claims that was not a smart investment because stereo equipment decreases in value at a rate of 9% per year. How much will his stereo equipment be be worth after 8 years?
Based on an exponential decay factor, Michael's stereo equipment will be worth $2,116 after 8 years, given the decreasing rate of 9% per year.
What is an exponential decay factor?The decay factor is represented by (1 - r), where r is the constant periodic decreasing rate.
The decay factor is used in exponential decay functions to determine the depreciated value of an asset.
Current price of stereo equipment = $2,500
Annual decreasing rate = 9%
Decrease factor = 0.91 (100% - 9%)
The number of years = 8 years
Value of the equipment after 8 years = ($2,500 x 0.91^8)
= $2,116.125 ($2,500 x 0.47025)
