Answer:
14.2 is the diameter.
Step-by-step explanation:
The radius squared = 52.
What you have given is the general equation of the circle with a center at (2,-3) and a radius of sqrt(52)
You can break the 52 down.
sqrt(52) = sqrt(4 * 13) = 2 sqrt(13). Notice that 4 is a perfect square.
d = 2*radius.
d = 2(2 sqrt(13) )
d = 4 sqrt(13)
That is the diameter. You want it to the nearest 1/10
d = 14.222 but it is to the nearest 1/10
d = 14.2
Answer:
Y=x+8
Step-by-step explanation:
To find the gradient of the line u have to subtract the y intercepts and the x intercepts
10-7/2--1=3/3=1
Y-7/x--1=1
Y-7=x+1
Y=x+1+7
Y=x+8
$105.40 is already rounded to the nearest dime '.'
