ANSWER
Frequency=2
Midline =3
Amplitude =5
Period =π
EXPLANATION
We have:

The given function is of the form;

where
a=|5| =5 is the amplitude
and b=2 is the frequency.
and 2π/b=2π/2=π
The range of the given function is
8≤y≤-2
The midline is

Answer:
A) increases
Step-by-step explanation:
5/x + 5
suppose x = 5; then 5/5 + 5 = 1 + 5 = 6
x = 2; then 5/2 + 5 = 2.5 + 5 = 7.5
x = 1 ;then 5/1 + 5 = 5 + 5 = 10
So when x value decreases from a large positive number to a small positive number, 5/x + 5 increases
The history museum is less that 9 4/5 miles. 9/10 means that the 9 3/4 mile is broken up into 10 equal parts and the distance to the museum is only 9 of those parts. 9 3/4 (9.8) divided by 10 equals 98/100 (.98)
98/100 x 9 = 882/100 or 8.82
Justin's house is 8.82 miles from the museum.
