Answer:
C. -5/2
Step-by-step explanation:
To find the slope you can use the slope formula:
We can pick 2 points from the table, I am going to use (3,5) and (1,10).
Plug these into the equation:
Therefore, the answer to the question is C. -5/2.

Answer:
A. $307,172.72
Step-by-step explanation:
Inez has to pay 4 percent in closing costs and 16 percent for the down payment on a purchase of $225,500 with an ARM.
4% + 16% = 20%
lnez has to pay 20% of $225,500
= 225,500*20/100
= 225,500*0.2
= $45100
lnez has to pay $45100.
Over the life of the loan, lnez will pay $262,072.72
Now we have to add down payment, closing cost and the payment over the life of the loan.
$45100 + $262,072.72
= $307,172.72
Answer: A. $307,172.72
Thank you.
Part A. You have the correct first and second derivative.
---------------------------------------------------------------------
Part B. You'll need to be more specific. What I would do is show how the quantity (-2x+1)^4 is always nonnegative. This is because x^4 = (x^2)^2 is always nonnegative. So (-2x+1)^4 >= 0. The coefficient -10a is either positive or negative depending on the value of 'a'. If a > 0, then -10a is negative. Making h ' (x) negative. So in this case, h(x) is monotonically decreasing always. On the flip side, if a < 0, then h ' (x) is monotonically increasing as h ' (x) is positive.
-------------------------------------------------------------
Part C. What this is saying is basically "if we change 'a' and/or 'b', then the extrema will NOT change". So is that the case? Let's find out
To find the relative extrema, aka local extrema, we plug in h ' (x) = 0
h ' (x) = -10a(-2x+1)^4
0 = -10a(-2x+1)^4
so either
-10a = 0 or (-2x+1)^4 = 0
The first part is all we care about. Solving for 'a' gets us a = 0.
But there's a problem. It's clearly stated that 'a' is nonzero. So in any other case, the value of 'a' doesn't lead to altering the path in terms of finding the extrema. We'll focus on solving (-2x+1)^4 = 0 for x. Also, the parameter b is nowhere to be found in h ' (x) so that's out as well.
