Answer:b
Step-by-step explanation:
While this problem seems confusing, the answer is rather simple.
All you have to do is the reverse of what they are asking.
This is, substract 8 to 60 and then divide by 4:

Answer:
3^4 = 81
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
We have
Here the value of a is always positive because distance is positive
Next, we factor out 7 to get our period
So our period is
Next, our phase shift we set the inner parenthesis equal to 0.
So our phase shift is -3/7
Basically, r=2t
A(r)=pir^2
sub 2t for r
A(2t)=pi(2t)^2
A(2t)=4pit²
A. A=4pit²
B. t=5
A=4pi5²
A=4pi25
A=100pi
A=314 square units
