Answer:
Option C and D that is y= tan x and y= cot x
Step-by-step explanation:
The range is the values of y means the values that y can take in a function:
So, range of tan x and cot x are all real numbers.
Period of tan x is 
Period of cot x is 
Option A and B that is secx and csc x are discarded
30 / 4.5 = 6.7...so the most 4 1/2 foot sections is 6
Answer:
C.) percent= 20%, Amount=unknown, Base =50
Step-by-step explanation:
The percent is the percent, so 20% is the percent.
The number you take the percent of is the base. The base is 50.
Once you calculate the percent of the base, you get the amount.
We are given the percent, 20%, the base, 50, but not the amount.
Answer:
k= 1 mile per minute
Step-by-step explanation:
There is a proportional relationship between the time (in minutes) Dave spends riding the train, x, and the distance he travels (in miles), y.
The table representing this information is given below:

The equation of proportionality is given as: y=kx
When x=8, y=8
Substituting we have:
8=8k
Divide both sides by 8
k=1
Therefore, the constant of proportionality, k= 1 mile per minute
