Definitely multiply out the given factors:
f(x) = 10 + 2x - 5x - x^2, or f(x) = -x^2 - 3x + 10
Find the derivative: f '(x) = -2x - 3
Set the deriv. = to 0 and solve for x: -2x = 3, and x = -3/2
This x = -3/2 is the x-coordinate of the max value. The y-coord. is
f(-3/2) = (-3/2)^2 - 3(-3/2) + 10 = 21.25
I realize that this result does not agree with any of the four possible answers. Please ensure that y ou have copied down this problem completely and correctly.
Answer:
<h2>n= -3</h2>
Step-by-step explanation:
Parameterize the line segments (call them 
and 
, respectively, by
both with 
. Then
The process here is finding out the smallest number's % towards the largest number.
Divide 20 by 52:
20/52 = 0.38 (estimated) | This is the % in decimal form, which is 38%.
Conclusion: 20 is 38% of 52.

Finding the Smallest Number:
What number is 25% of 60?
Multiply 60 by the decimal form of 25%.
60 * 0.25 = 15 | 15 is 25% of 60.
Finding the Percentage. (Like what we already did.)
30 is what percent of 150?
Divide 30 by 150.
30/150 = 0.2 | 30 is 20% of 150.
Finding the Largest Number.
12 is 30% of what number?
Divide 12 by the decimal form of 30%.
12/0.3 = 40 | 12 is 30% of 40.
I hope this helps, have a great rest of your day! ^ ^
