Answer:
1) If the function is
, 
2) If the function is
, 
3) If the function is
, 
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
f(6) means that you must substitute x=6 into the function above.
1. If the given the function
, you obtain:

2. If the function is 
Then:

3. If the function is 
Then:

I cant help you but i have a great app that can its called photo math. its very good. if you dont agree its fine
I = Adt; where p = $290 is the Amount of the loan, d = 16% = 0.16 is the discount rate and t = 90days = 90/365 = 18/73 is the period.
I = 290 x 0.16 x 18/73 = 11.44
Interest = $11.44
Proceed = Amount - Interest = 290 - 11.44 = $278.56
Height=4 ft
angle=33 degrees
My tip first is to draw it out. Draw an acute angle opening up to a building forming a triangle. Inside of the vertex of the acute angle is the degree 33 and the height of the building is 4 ft. So, use trig! Do you have a calculator? Opposite over hypotenuse is Sine. (SOH CAH TOA). (4)/(sin(33)). which equals 7.34 ft as your height! Hope this helped!
