Answer:
10x -5 +5h
Step-by-step explanation:
Use the function definition with the given arguments.
![\dfrac{f(x+h)-f(x)}{h}=\dfrac{(5(x+h)^2-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{(5(x^2+2hx+h^2)-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{5x^2+10hx+5h^2-5x-5h-5x^2+5x}{h}=\dfrac{10hx-5h+5h^2}{h}\\\\=\boxed{10x-5+5h}](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D%3D%5Cdfrac%7B%285%28x%2Bh%29%5E2-5%28x%2Bh%29%29-%285x%5E2-5x%29%7D%7Bh%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%285%28x%5E2%2B2hx%2Bh%5E2%29-5%28x%2Bh%29%29-%285x%5E2-5x%29%7D%7Bh%7D%5C%5C%5C%5C%3D%5Cdfrac%7B5x%5E2%2B10hx%2B5h%5E2-5x-5h-5x%5E2%2B5x%7D%7Bh%7D%3D%5Cdfrac%7B10hx-5h%2B5h%5E2%7D%7Bh%7D%5C%5C%5C%5C%3D%5Cboxed%7B10x-5%2B5h%7D)
Answer:
Table F
Step-by-step explanation:
The equation is C = 0.75t. The variable c is for cost and t is for tickets. When we use substitution to solve the equation, we see that table F correctly represents the situation. In simpler terms, the equation is asking us to mutliply the cost PER ticket by the number of tickets.
0.75 * 1 = 0.75
0.75 * 2 = 1.50
0.75 * 3 = 2.25
0.75 * 4 = 3
And so on. As we can see, the only table that shows these values is in fact table F.
Hope this helps!

Answer:
The approximate growth rate of the savings account is 2.5%
Step-by-step explanation:
Given the the function S(x) = 5, 000 * (1.025) ^ (0.7x)
From the function, we can see that part: (1.025). It presents for the growth factor or rate with the formula as:
(1 + r) where r is rate
So we have:
(1 + r) = 1.025
<=> r = 1.025 -1
<=> r = 0.025
In pecentage, we have the rare: 0.025 *100% = 2.5%
So the approximate growth rate of the savings account is 2.5%
