Answer:
radius:5
center (2,-4)
Step-by-step explanation:
the equation of a circle is

where the center is (h,k) and the radius being r
this would mean that for your specific equation,
h=2
k=-4
and r=
= 5
so in order to graph the circle you start at (2,-4) and measure the distance of 5 units on your compass and graph it!
use y=mx+b as an formula m=y2-y1 over x2-x1 or tey this

Answer:
a)
g(3.5), g(26.92)
or
g(3.5)=3.5^2, g(26.92)=26.92^2
Answer:
22 yd
Step-by-step explanation:
Length is four times its width -----> L=4W
area of rectangle is 196 -----> 196=LW
Plug L=4W into 196=LW giving you 196=(4W)W
Simplify a bit 196=4W^2
Divide both sides by 4: 196/4=W^2
Simplify a bit: 49=W^2
Square root both sides: 7 or -7=W
The width is 7 yd
The length is 4(7)=28 yd
Now its final part is for you to find the perimeter of this rectangle. The rectangle is a 7 yd by 4 yd rectangle.
Double both then add.. 14+8=22 yd
