Angles of Elevation and Depression are used in measuring heights and distances in trigonometric applications using right triangles. These angles are made when we look up or down to view objects. Devices are available to measure angles of elevation and depression. These measured angles can be used in measuring heights and distance which are either tedious or impractical to measure, by modelling the situation into right triangles
The inverse of the function is f(x) =
+ 8
In order to find the inverse of any function, start by switching the f(x) and x. Then solve for the new f(x). The result will be the inverse function. The work is below for you.
f(x) =
----> Switch f(x) and x
x =
----> Cube both sides
= f(x) - 8 ----> Add 8 to both sides
f(x) =
+ 8
When factoring find 2 numbers that when added together equal the middle value and when multiplied equal the last value.
min this problem the middle value is 7 and the last value is 10
5 + 2 = 7 and 5 x 2 = 10
The answer is: (x+2)(x+5)
Simple...
you have:
![\frac{n}{3} =12 ](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%7D%7B3%7D%20%3D12%0A)
and
![\frac{n}{3} =-12](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%7D%7B3%7D%20%3D-12)
To solve for....
![\frac{n}{3} =12](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%7D%7B3%7D%20%3D12)
Multiply to remove the denominator-->>
![3* \frac{n}{3} =12*3](https://tex.z-dn.net/?f=3%2A%20%20%5Cfrac%7Bn%7D%7B3%7D%20%3D12%2A3)
n=12*3
n=36
Then-->>>
![\frac{n}{3} =-12](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%7D%7B3%7D%20%3D-12)
Do the same thing-->>
![3* \frac{n}{3} =-12*3](https://tex.z-dn.net/?f=3%2A%20%5Cfrac%7Bn%7D%7B3%7D%20%3D-12%2A3)
n=-12*3
n=-36
Thus, your answer.
