The swan family installs an aboveground pool. the circular pool covers about 78.5 square feet of lawn in the backyard. what is the length, in feet, of the edge of the pool.

The length of the edge of the pool is 31.4 feet.

Step-by-step explanation:

Given:

The circular pool covers about 78.5 square feet of lawn

To Find:

The length of the edge of the pool = ?

Solution:

The area of the circular pool = 78.5 square feet

r = 5 feet

Now the the length of the edge is the circumference of the circle

=>

=>

=>

=> 31.4 feet

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
