I'm currently learning this but what I'm being taught is different, after the question there should be an integer. It should look like this, (f (open circle) g)(any number) Due to the lack of number I'm not sure what to do. If there was a number then you plug that number into g and whatever you get you plug into F.

If the area of a circle is 58 square feet, find the circumference. A. 42.5 ft. B. 4.25 ft. C. 22.35 ft. D. 26.99 ft.

PSYCHO15rus [73]

Answer: OPTION D.

Step-by-step explanation:

The formula for calculate the circumference of a circle is:

$C=2r\pi$

Where <em>r</em> is the radius.

The formula for calculate the area of a circle is:

$A=r^2\pi$

Where <em>r</em> is the radius.

Solve for <em>r</em> from $A=r^2\pi$ to calculate it:

$r=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{58ft^2}{\pi}}\\r=4.296ft$

Subsitute the radius into $C=2r\pi$ . Then:

$C=(2)(4.296ft)\pi=26.99ft$

Step-by-step explanation:

I've posted solutions in the picture. Rather the ways to solve them. Check and find answers on your own.

Also, I've not solved the problem by differential calculus. You can, obviously, if you're interested. Use it for ease and for tougher equations.

What is the rate of change of the function y = − 1/4 x + 1

scoray [572]

Answer:

-1/4

Step-by-step explanation:

Hello!

The rate of change is also known as the slope.

Standard equation of a line: y = mx + b

y: output
m: slope
x: input
b: y-intercept

So, if we match the standard form to the given function:

y = mx + b
y = -1/4x + 1

-1/4 is m, or the rate of change.
