Answer:
f(-10) = 2 times -10 + 1
= -19
f(2) = 2^2
= 4
f(-5) = 2 times -5 + 1
= -9
f(-1) = (-1)^2
= 1
f(8) = 3-8
= -5

Answer:
207.24 in²
Step-by-step explanation:
The "r" in the formula stands for the radius of the cylinder. That is half the diameter, so is 3 in. The "h" in the formula stands for the cylinder height, shown as 8 in. Put these values in the formula and do the arithmetic.
SA = 2πr(r +h) = 2(3.14)(3 in)(3 in + 8 in) = 6.28(33 in²)
SA = 207.24 in²
Answer:
0.185 Step-by-step explanation:
(2.4 x 10^-1) - (5.5 x 10^-2)

Answer:
the perimeter is of 148 m
Step-by-step explanation:
the perimeter is the sum of all sides so an square has all sides equal so we have
and the area is
so we find x
and now the perimeter
