<h3>Answer: Approximately 25.12 meters</h3>

This value is approximate because pi = 3.14 is approximate

===========================================================

Work Shown:

r = 4 = radius

pi = 3.14 approximately

C = circumference

C = 2*pi*r

C = 2*3.14*4

C = 25.12

The circumference is approximately 25.12 meters.

Side note: The circumference is the same as the perimeter of a circle.

Find the output, g, when the input, r, is 3.<br> g = -5r+13<br> g=_____

bija089 [108]

Answer:

g = -2

Step-by-step explanation:

g = -5r + 13

r = 3

You substitute three for r in the equation.

--------------------------------------------------------------

g = -5(3) + 13

--------------------------------------------------------------

Distribute -5 to 3

--------------------------------------------------------------

g = -15 + 13

--------------------------------------------------------------

Solve

-------------------------------------------------------------

g = -15 + 13

-15 + 13 = -2

g = -2

The graph of y=1/x is shown below. Draw the graph of its inverse.

lord [1]

Y=1/x solve for x

x=1/y now reverse lables...

y=1/x

Yes that is the same equation you started with. What that means is the the inverse function in this case produces the same exact graph :)
