Five Friends completed a triathlon that included a 3-mile run, a 12-mile bike ride, and a mile swim. To compare their running times they created a table that shows the difference
between each person's time and the average time, with negative numbers representing
time less than average time, with negative numbers representing time less than average.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

dont think so

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

i would love   to but there is no graph shown
