Find, to the nearest tenth, the area of the region that is inside the square and outside the circle. the diameter of the circle

Doss [256]

Answer:

Option $42.1\ in^{2}$

Step-by-step explanation:

we know that

The area of the region that is inside the square and outside the circle is equal to the area of the square minus the area of the circle

see the attached figure to better understand the problem

Step 1

Find the area of the square

Remember that

The area of the square is

$A=b^{2}$

where

b is the length side of the square

we have

$b=14\ in$

substitute

$A=14^{2}=196\ in^{2}$

Step 2

Find the area of the circle

Remember that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=14/2=7\ in$

substitute

$A=\pi(7^{2})=153.9\ in^{2}$

Step 3

Find the area of the region

$196\ in^{2}-153.9\ in^{2}=42.1\ in^{2}$

Which of the following functions I which of the following functions are one to one? Select all that apply there are 3 answers

ivann1987 [24]

Answer:

The function $f(x)=\frac{x-1}{3x+3}$ is one-to-one function ⇒ 1st

The function $f(x)=\sqrt{5x+9}$ is one-to-one function ⇒ 2nd

The function $f(x)=\frac{1}{2}x^{3}$ is one-to-one function ⇒ 4th

Step-by-step explanation:

* Lets explain how to solve this problem

- One to one function is the function that has no reputation in the value

of the y-coordinates for every corresponding x-coordinates

- That means when you draw a horizontal line at any value of y, then

the horizontal line intersects the graph of the function at one point

only

- So to solve the problem look to the attached figures
