Aradio station has a broadcast area in the shape of a circle with equation
x^2+y^2=5,625, where the constant represents square miles.

1. find the intercepts of the graph. (there are 4)
2. state the radius in miles.
3. what is the area of the region in which the broadcast from the station can be picked up?

1)

2)

3)

Step-by-step explanation:

The general equation of a circle has the form:

Where r is the radius of the circumference.

In this problem we have the circle with equation

1) The intercepts with the x-axis we find them doing y = 0 and solving for x:

The intercepts with the y-axis we find them doing x = 0 and solving for y:

The 4 interceptions are:

2) The radius is:

3) The area of a circumference is:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
