Answer:
Option C
Step-by-step explanation:
Use the property to convert each expression from exponent form to radical form.
[tex](a)^{\frac{1}{n}}=\sqrt[n]{a}[/tex]
a). [tex](b)^{\frac{4}{5}}=(b^4)^\frac{4}{5}[/tex]
[tex]=\sqrt[5]{b^4}[/tex]
b). [tex](8x)^\frac{2}{3}=[(8x)^2]^\frac{1}{3}[/tex]
[tex]=[64x^2]^\frac{1}{3}[/tex]
[tex]=[(4)^3x^2]^\frac{1}{3}[/tex]
[tex]=(4^3)^\frac{1}{3}(x^2)^\frac{1}{3}[/tex]
[tex]=4(x^2)^\frac{1}{3}[/tex]
[tex]=4\sqrt[3]{x^2}[/tex]
Therefore, Option C will be the answer.

Step-by-step explanation: the way i did it:
first find the radius, 34 divided by 2 = 17π
then multiply the radius by itself 17 x 17 = 289
after, multiply 289 by 27 to get 7,803
then multiply 7803 by 3.14 to get 24,501.42
Hope this is correct!
(p.s.) if you do it on a calculator and use the pi symbol (π) the answer would be 24,513.84

Suppose that the length of a certain rectangle is two centimeters more than three times its width. If the area of the rectangle is 85 square centimeters, find its length and width
Answers
Answer:
width = 5 in
length = 17 in
Step-by-step explanation:
Area of a rectangle = length x width
width = w
length = 2 + 3w
85 = (w) x (2 + 3w)
85 = 2w + 3w³
this can be solved using quadratic equation
3w³ + 2w - 85 = 0
factors of 3w³ x -85 that add up to 2w are : +17 w and -15w
(3w³ - 15w) (17w - 85) = 0
3w(w - 5) 17(w - 5) 0
w = 5
or w = - 17/3
the width cannot be a negative number. the correct width is 5 in
Length = 2 x 3(5) = 17 inches

find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Answers
Answer:
0.2985
Step-by-step explanation:
find cot0 given cos0=2/7 and the terminal side is in quadrant IV
Given
cos theta = 2/7
theta = arccos(2/7)
theta = 73.40 degrees
cot theta = cot73.40
cot73.40 = 1/tan73.40
cot73.40 = 1/3.35
cot73.40 = 0.2985
hence the required answer is 0.2985
easy question for anyone SLIGHTLY smarter than me pls help I don’t know how to do this
Answers
They make it all so complicated with all of the complex lines doing their own thing, though this is somewhat straight forward once you see it.
With the Domain, these are the x values that the line covers.
For this, it would be -5 ≤ x ≤ 4, because all of the x values are between these two values.
With the Range, these are the y values that the line covers.
For this, it would be -4 ≤ x ≤ 5, because all of the y values are between these two values.
With the X-Intercepts, these are the x values the line crosses for when the y value is 0.
For this, it would be -3 and -1.
With the max, it is the highest point within a graph, for where the y value is the greatest.
For this, it would be x = 4 at the coordinate (4, 5).

Find the slope of the line on the graph.
Write your answer as a fraction or a whole
number, not a mixed number or decimal.
Answers
Answer:
The slope is 1
Step-by-step explanation:
Take any two points from the graph and plug it into the equation y1-y/x1-x. I took the point (0,3) and (1,4). Plug these two points in to get 4-3/1-0. Simplify to get 1/1 which is equal to 1. Therefore, the slope is 1.
If this answer helps please mark as brainliest
Answer:
The slope is 1
Step-by-step explanation:
There are multiple ways to find the slope on a graph. You can either take two points from the line and do it the normal way (y1-y2/x1-x2), or you can look at the graph and see how much it "rises and runs" from one point to the next point. Since this is a pretty simple graph that is the method I used. Count how many units the line goes up and to the right from one point to the next, and remember the phrase "rise over run" for organizing the fraction. In this one, it rises one and runs one, so 1/1, and that's 1. I hope I could help.

Sale price:
Answers
Answer:
14.25
Step-by-step explanation:
So, lets go over our information.
We have a price of 15 dollars.
And it is 5% cheaper.
This means that the price is 95% of what it used to be.
We must find 95% of 15.
We know that to put 95% into decimal form, we must divide by 100:
95/100
=
0.95
So we know we must multiply 15 by 0.95:
15x0.95
=
14.25
So our price is now 14.25 dollars
hope this helps! :)

Answers
Answer:
x = 14/5
Step-by-step explanation:
2x-4= -x-6/2
multiply by 2 on both sides to get rid of the fraction
4x-8= -x-6
add both sides by 8 and both sides by x to get the constants on the right and the variables on the left
4x+x=6+8
combine like terms/simplify
5x=14
divide both sides by 5 to isolate the x
x=14/5

Answers
Step-by-step explanation:
It is Graph B. We can do this by checking the points. The equation given is d = 5t^2, where d technically is the y-coordinate and t is the x-coordinate. On Graph B, two obvious points are (1, 5) and (2, 20). We can check these points to see if they fit the equation.
(1,5): d = 5t^2
5 = 5(1)^2
5 = 5*1
5 = 5, so this point is correct.
(2, 20): = d = 5t^2
20 = 5(2)^2
20 = 5*4
20 = 20, so this point is correct.
We know that Graph A is incorrect because it doesn't follow the equation. The line goes through (1, 5), which we already know is correct, (2, 10), (3, 15), and (4, 20). We already figured out that (2, 20) is correct so (2,10) can't be correct. (3, 15) and (4, 20) are also incorrect but in this case, we only need to find one incorrect coordinate to validate our answer. Thus, as Graph A is wrong, Graph B is right.
