Given the polynomial of degree 4, this can be written as:
x^4-100
let
x^2=a
thus the expression can be written as:
a^2-100
this is a polynomial of degree 2 also known as quadratic equation.
Hence the answer is:
<span>A) Quadratic formula</span>
The original price would be 260 I think. Because if they paid 25% that should be 1/4 so add 65 three more times.
Answer: B. -(x-2)^2 + 3
The vertex of the parabola is (2,3) so we can plug in those values into the equation for vertex form. And the parabola is facing down, so we know the function is multiplied by -1.
Therefore the equation is -(x-2)^2 + 3
Look at the attached image to see what vertex form is
Your answer is c, 638.54 − 159.50 + x ≥ 500; x ≥ $20.96
Knowns:
C = mx + b
m = 367
b = 1500
C = 367x + 1500
Cost (c) = 16,600
16600 = 367x + 1500
subtract 1500 from both sides
15,100 = 367x
Divide both sides by 367
x = 41.14
