Answer:
Step-by-step explanation:
(x-5)2+8 = 92
2x-10+8 = 92
2x = 94
x = 47
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
Answer:
Changing value of "d" changes the vertical shift of the cosine graph.
Step-by-step explanation:
Question says to find about how does your cosine graph change when including the d-value.
General equation of cosine function can be given as:

In that formula, value of "d" gives vertical shift.
So changing value of "d" changes the vertical shift of the cosine graph.
First You would divide both numbers by ten to get 15 and 25. Then you realize that both numbers are divisible by 5 so you divide both sides you then end up with 3 to 5 which is your answer.
It should be the second one
