Answer:
Step-by-step explanation:
Given that Drake wants to save $750 so that he can take a class on computer analysis for cars.
He wants to save 125 per week for 6 weeks.
.Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470.
If he wants to have 750 after 6 weeks, he has to save 
$ per week
Or alternately he can save same 125 dollars so that he would have 750 $ in
3 weeks.
A: Stay with saving the original amount each week but take the class a week later than originally planned.Option B: Increase the amount of money he saves each week by $15 from his original plan.
Both are right.
c. Both options A and B will allow him to meet his goal.
A right triangle? because it has angle measures or 45, 45, 90.
Harriet works 42 hours a week. She gets paid £9.12 for each hour she works. An estimated amount Harriet gets paid in a week is £378
<h3>How to calculate the percent error?</h3>
Ssuppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
Harriet works 42 hours a week. She gets paid £9.12 for each hour she works.
1 hour = £9.12
Estimated
£9 x 42 hours = 378
Actual
£9.12 x 42 hours = 383.04

To solve this, you have to know that the first derivative of a function is its slope. When an interval is increasing, it has a positive slope. Thus, we are trying to solve for when the first derivative of a function is positive/negative.
f(x)=2x^3+6x^2-18x+2
f'(x)=6x^2+12x-18
f'(x)=6(x^2+2x-3)
f'(x)=6(x+3)(x-1)
So the zeroes of f'(x) are at x=1, x=-3
Because there is no multiplicity, when the function passes a zero, he y value is changing signs.
Since f'(0)=-18, intervals -3<x<1 is decreasing(because -3<0<1)
Thus, every other portion of the graph is increasing.
Therefore, you get:
Increasing: (negative infinite, -3), (1, infinite)
Decreasing:(-3,1)
