In this situation you would use cos 
which is adjacent over hypotenuse 
so I take the cos50 and have it equal to 17 / x
 cos(50)= 17/x 
which is the same as ...
17 divided by cos(50) =x 
x=26.44730506
which rounds to 26.45 
So your answer would be A)

I hope everything makes sense, enjoy! <span />

The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $
ValentinkaMS [17]

Answer:

Future Value = $ 12528.15

Step-by-step explanation:

The depreciation is applied to the car annually. The value of the car after depreciation in "n" no. of years can be given by the following formula:

Future\ Value = (Present\ Value)(1-depreciation\ rate)^n\\

where,

Future Value = ?

Present Value = $ 24000

Depreciation Rate = 15% = 0.15

n = no. of years = 4

Therefore,

Future\ Value = (\$ 24000)(1-0.15)^4

<u>Future Value = $ 12528.15</u>

(h(1) = 96<br> (h(n) = h(n − 1) - 1<br> Find an explicit formula for h(n).
Lubov Fominskaja [6]

Answer:

a_n=97-n

Step-by-step explanation:

Given:

h(1)=96\\ \\h(n)=h(n-1)-1

Find first terms:

h(1)=96\\ \\h(2)=h(2-1)-1=h(1)-1=96-1=95\\ \\h(3)=h(3-1)-1=h(2)-1=95-1=94\\ \\h(4)=h(4-1)-1=h(3)-1=94-1=93\\ \\....

In this arithmatic sequence, each next term is 1 less than the previous term.

The general explicit formula is

a_n=a_1+(n-1)d

In your case,

a_1=96\ \text{   First term}\\ \\d=-1\ \text{   Common difference}

Then

a_n=96+(n-1)\cdot (-1)\\ \\a_n=96-(n-1)\\ \\a_n=96-n+1\\ \\a_n=97-n
