Answer:
I'll setup the problem and leave the computation to you
Step-by-step explanation:
The equation to calculate fixed payments
P= payments
r = interest rate for the period (which is a quarter )
PV = present value (or the amount borrowed)
n = number of periods
r = .25/4 (4 months = quarter of a year)
n = 4*10
PV = R450550.00

Answer:
The correct choice is C
Step-by-step explanation:
The given function is:
The degree of this function is odd so the function will rise at one end and fall on the other end.
Since the coefficient of the leading term is negative, the graph of the function will rise at the left and fall on the right.
The correct answer is option C.
Answer:
Step-by-step explanation:
This is a third degree polynomial since we have 3 zeros. We find these zeros by factoring the given polynomial. The zeros of a polynomial are where the graph of the function goes through the x-axis (where y = 0). If x = -4, the factor that gives us this value is (x + 4) = 0 and solving that for x, we get x = -4. If x = -2, the factor that gives us that value is (x + 2) = 0 and solving that for x, we get x = -2. Same for the 5. The way we find the polynomial that gave us these zeros is to go backwards from the factors and FOIL them out. That means that we need to find the product of
(x + 4)(x + 2)(x - 5). Do the first 2 terms, then multiply in the third.
, which simplifies to
No we multiply in the final factor of (x - 5):
which simplifies to
If you are aware of the method for factoring higher degree polymomials, which is to use the Rational Root Theorem and synthetic division, you will see that this factors to x = -4, -2, 5. If you know how to use your calculator, you will find the same zeros in your solving polynomials function in your apps.
