Answer:
D. 
Step-by-step explanation:
Any parabola is modelled by a second-order polynomial, whose standard form is:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
, 
, 
- Coefficients, dimensionless.
In addition, a system of three linear equations is constructed by using all known inputs:
(-2, 0)
(Eq. 1)
(4, 0)
(Eq. 2)
(0,-16)
(Eq. 3)
Then,
(Eq. 4)
(Eq. 5)
(Eq. 3 in Eqs. 1 - 2)
By Eq. 4 (Eq. 4b)
Then,
(Eq. 4b in Eq. 5)
The remaining coeffcient is:
The function that represents a parabola with zeroes at x = -2 and x = 4 and y-intercept (0,16) is . Thus, the right answer is D.

=75-12(12.50)
=75-150
=-75
She will have negative $75 so she will be below zero.

Answer:8^4 + 14^36 is the perimeter because they are for sides in a rectangle so you have to double the amount.
<u>ANSWER</u>
<u>EXPLANATION</u>
The Cartesian equation is
We substitute
and
This implies that
Let us evaluate the exponents to get:
Factor the RHS to get:
Divide through by r²
Apply the double angle identity
The polar equation then becomes:
