Answer:
15
Step-by-step explanation:
just took the test. x=5 and the answer to the equation is 15
It’s the 3rd one hopefully this helps
Answer:
The co-ordinates of the vertex of the function y-9= -6(x-1)^2 is (1, 9)
<u>Solution:</u>
Given, equation is ![y-9=-6(x-1)^{2}](https://tex.z-dn.net/?f=y-9%3D-6%28x-1%29%5E%7B2%7D)
We have to find the vertex of the given equation.
When we observe the equation, it is a parabolic equation,
We know that, general form of a parabolic equation is
Where, h and k are x, y co ordinates of the vertex of the parabola.
![\text { Now, parabola equation is } y-9=-6(x-1)^{2} \rightarrow y=-6(x-1)^{2}+9](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Now%2C%20parabola%20equation%20is%20%7D%20y-9%3D-6%28x-1%29%5E%7B2%7D%20%5Crightarrow%20y%3D-6%28x-1%29%5E%7B2%7D%2B9)
By comparing the above equation with general form of the parabola, we can conclude that,
a = -6, h = 1 and k = 9
Hence, the vertex of the parabola is (1, 9).
1st year 500* 0.03 = 15+500=515
2nd year 515*0.03= 15.45 + 515 = 530.45
3rd year 530.45*0.03= 15.9135 + 530.45 = 546.3635
4th year 546.3635 * 0.03 = 16.390905 + 546.3635 = 562.754405
562.754405
