Answer:
Step-by-step explanation:
f(3) = 8^3 + 7 = 512 + 7 = 519
Answer:
Step-by-step explanation:
Answer:
A = 121 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi*r
22 pi = 2 * pi *r
Divide each side by 2 pi
22 pi / (2 pi) = 2 pi r / (2pi)
11 = r
Now find the area
A = pi r^2
A = pi (11)^2
A = 121 pi in^2
2 and 4 because they all multiply and add up to 12 and 20
M is the slope.
B is the y-intercept
The constant of proportionality is the ratio between two directly proportional quantities.
