transformations of function 3(-7(x+2))-4
- vertical stretch
- horizontal compression
- translates left
- translates down
- reflection across y-axis
A typewriter costing $75.00 marked up 40% on cost M = 40 and S = 105
If its volume (Not so sure about surface area?) than its 432 inches^3
We can display the information given as an equation:
2000 *
![r^{19}](https://tex.z-dn.net/?f=%20r%5E%7B19%7D%20)
= 4000; r = increase per annum
Now, we rearrange and solve for r:
![r^{19}](https://tex.z-dn.net/?f=%20r%5E%7B19%7D%20)
= 2
r =
![\sqrt[19]{2}](https://tex.z-dn.net/?f=%20%5Csqrt%5B19%5D%7B2%7D%20)
= 1.037.....
We can now work out the increase for 5 years like so:
2000 *
![r^{5}](https://tex.z-dn.net/?f=%20r%5E%7B5%7D%20)
= 2400.205..... ⇒
$2400
5(3-6x)=4(3x+7)+5x
x= - 13/47
