We are given the following information:
the sum of the first number cubed and the second number is 500
their product is a maximum
We are looking for the 2 missing numbers.
To answer this, let's represent the two numbers as x and w.
From the given, we can form the following equation:
We can then express y as:
We can express their product as:
To find the maximum value of x, let's solve for the derivative of -x^4 + 500 x.
Then we solve for the value of x where f'(x) = 0.
Then we use x = 5 to solve for the second number, w.
Therefore, the two numbers are 5 and 375.
Answer:
D. y = -(x-5)(2x+1)(x+3)
Step-by-step explanation:
"r" is a zero of the polynomial when (x -r) is a factor.
The three given zeros mean that (x -5), (x -(-1/2)), and (x -(-3)) will be factors of the equation. The product of the constants in these binomials (and any vertical scale factor) must be equal to the y-intercept.
For some scale factor "a", we want ...
(a)(-5)(1/2)(3) = 15
a = 15/(-7.5) = -2
and the desired polynomial function is ...
y = -2(x -5)(x +1/2)(x +3 = -(x -5)(2x +1)(x +3) . . . . matches choice D
