Answer: A
Step-by-step explanation:
Answer:
20/3
Step-by-step
(base1+base2)/2 * height = area of a trapezoid
64/12=16/3
16/3*2 = 32/3
32/3-4 = 20/3
Answer:
c

Answer:
9
Step-by-step explanation:
LN = LM - MN
= 16 - 7 = 9

So, the function is obviously shifted up by 1 so it rules out A and B, and we also see that the period is 4pi rather than 2pi, and using the fact that:

Now that we know our b value, we see that the correct answer would be C.
