1100/80=13.75,the answer is 13.75.So Tyler earn 13.75
Answer:
![y = \frac{1}{4} (4) {}^{x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%20%284%29%20%7B%7D%5E%7Bx%7D%20)
Step-by-step explanation:
An exponetial function is represented by
![y = ab {}^{x}](https://tex.z-dn.net/?f=y%20%3D%20ab%20%7B%7D%5E%7Bx%7D%20)
where a is the vertical stretch or initial rate and b is the factor or base.
Since neither point have a x coordinate of zero. Use this method.
plug in y value into the formula and x value into there as well like this
![16 = ab {}^{3}](https://tex.z-dn.net/?f=16%20%3D%20ab%20%7B%7D%5E%7B3%7D%20)
![4 = {ab}^{2}](https://tex.z-dn.net/?f=4%20%3D%20%20%7Bab%7D%5E%7B2%7D%20)
if you divide the second equation from the first
![\frac{16 = ab {}^{3} }{4 \ = ab {}^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%20%3D%20ab%20%7B%7D%5E%7B3%7D%20%7D%7B4%20%5C%20%3D%20ab%20%7B%7D%5E%7B2%7D%20%7D%20)
![4 = b {}^{}](https://tex.z-dn.net/?f=4%20%3D%20b%20%7B%7D%5E%7B%7D%20)
so our equation now is
![y = a(4) {}^{x}](https://tex.z-dn.net/?f=y%20%3D%20a%284%29%20%7B%7D%5E%7Bx%7D%20)
know let plug one of the point in to find a
Use 3,16
![16 = a(4) {}^{3}](https://tex.z-dn.net/?f=16%20%3D%20a%284%29%20%7B%7D%5E%7B3%7D%20)
![16 = a \times 64](https://tex.z-dn.net/?f=16%20%3D%20a%20%5Ctimes%2064)
![\frac{16}{64} = a](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%7D%7B64%7D%20%20%3D%20a)
![a = \frac{1}{4}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%20)
So our equation is
![y = \frac{1}{4}(4) {}^{x}](https://tex.z-dn.net/?f=%20y%20%3D%20%20%5Cfrac%7B1%7D%7B4%7D%284%29%20%7B%7D%5E%7Bx%7D%20)
26+10i, 26-10i
I'm assuming the 26 is not under the radical
Yes, because 11 2/3 is rounded to 12. and 2 5/6 is rounded to 3. 12 divided by 3 is 4. 4 2/17 is rounded to 4. 4 =4
