Answer:
(1) . -11
Step-by-step explanation:
f(-2)=-3(-2)^2+
-12+1=-11
The question is asking you to solve for A
to determine the first, fourth and tenth term you simply put those values in for (n)
the first term you then be given by the equation A(1) = 12 + ((1)-1)(3)
A= 12
Same thing for 4th term A(4) = 12 + ((4)-1)(3)
A= 21
10th term: A(10) = 12 + ((10)-1)(3)
A= 39
∴ your answer is C
P = 2(L + W)
L = 4/3W
P = 2(4/3W + W) <=== part 1 is D
when P = 28
28 = 2(4/3W + W)
28/2 = 4/3W + 3/3W
14 = 7/3W
14 / (7/3) = W
14 * 3/7 = W
42/7 = W
6 = W....width is 6 inches
L = 4/3W
L = 4/3(6)
L = 24/3
L = 8....length is 8 inches
A = L * W
A = 8 * 6
A = 48 in^2 <==== part 2
