131.818182% and can round to 131.82
Answer:
Step-by-step explanation:
Ok so to find constant of proportionality, you need to find K.
X would be gallons and y is cost.
To find k you need to do k=y/x
k=17.50/5
k=3.5
That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.
k=35/10
k=3.5
k=52.50/15
k=3.5
For all of those 3.5 was constant.
Because they are constant, that means the data in the graph is a proportion.
An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.
k=52.50/16
k=3.28
That be different from the other 3.5's meaning its not proportional. But that's just an example.
If you need extra help reach out to me and I'll help you best I can. I hope this helps though. <3
Answer:
Answer is 9/8
Step-by-step explanation:
18/8-9/8=9/8
The critical values of the function are x = 0 and x = 64
The critical values of a function f(x) are the values of x for which f'(x) = 0.
Given,
f(x) = 
The derivative is found as follows, applying the quotient rule:
f'(x) = ![\frac{[5(x^{4} )(x-8)^{2}-5x^{4} [(x-8)^{2} ]' }{[5(x-8)^{2} ]^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5B5%28x%5E%7B4%7D%20%29%28x-8%29%5E%7B2%7D-5x%5E%7B4%7D%20%5B%28x-8%29%5E%7B2%7D%20%5D%27%20%7D%7B%5B5%28x-8%29%5E%7B2%7D%20%5D%5E%7B2%7D%20%20%7D)
= 
The zeros of the function are the zeros of the numerator, thus:
x - 64 = 0------------->x = 64
The critical values are x = 0 and x = 64
