We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.
This gives
f'(x) = 7
Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.
Answer:
3
Step-by-step explanation:
if $35 is per hour plus 20=
35+20=55
55+35=90
90+35=125
So that would mean you would have water skied for 3 hours
Similar triangles have side lengths that are proportional.
We setup a proportion using the given information.
AB/LM = BC/MN
8/12 = 14/MN
8(MN) = 12 * 14
8(MN) = 168
MN = 168/8
MN = 21
Answer:
