Answer:
see explanation
Step-by-step explanation:

The cosine function in standard form is
y = acos(bx + c)
where a is the amplitude, period = 
and
phase shift = - 
here b = 2 and c = 
, thus
phase shift = - 
= - 
2
the amplitude = | a |
which has a maximum of a and a minimum of - a
y = 4cosx ← has a maximum value of 4
the answer would be -8<x<2
Use distributive method
5r - 50 = -51
Add 50
5r = -1
Divide by 5
r = -1/5
Answer:
The first option, the mayor will lose by a large percentage.
Step-by-step explanation:
If you look at the numbers, You can see that the two best answers which are excellent and satisfactory are low, and in total equal 28.
Being compared to the lower ratings which are needs improvement and unsatisfactory are high, and in total equal 52.
Seeing this, this shows that the mayor will lose the election the with more than half of the people voting for someone else.
All the other options excluding the first one, say that he will win by a close call, a big percent, or a close call again.
which just leaves the first option saying that he will lose by large percent, which is true.
