Answer:

C. 4

Step-by-step explanation:

<u>Given function:</u>

y = 5x² – 20x + 24

<u>Convert the equation into vertex form:</u>

y = 5x² - 20x + 20 + 4 =
5(x² - 4x + 4) + 4 =
5(x - 2)² + 4

Vertex is (2, 4) at which the minimum y-value is 4

Correct choice is C

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms. Third-degree, with zeros of −3

RSB [31]

Answer:

$\Large \boxed{-\dfrac{5}{4}(x+3)(x+1)(x-2)}$

Step-by-step explanation:

Hello,

Based on the indication, we can write this polynomial as below, k being a real number that we will have to identify (degree = 3 and we have three zeroes -3, -1, and 2).

$\Large \boxed{k(x+3)(x+1)(x-2)}$

We know that the point (1,10) is on the graph of this function, so we can say.

$k(1+3)(1+1)(1-2)=10}\\\\4*2*(-1)*k=10\\\\-8k=10\\\\k=\dfrac{10}{-8}=-\dfrac{5}{4}$

Then the solution is:

$\large \boxed{-\dfrac{5}{4}(x+3)(x+1)(x-2)}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

we do not know how much the price of a commodity is, but it has been reduced by 10% and now costs 20€. What was the starting pri

MrRissso [65]

I got 22 because if u do 20 multiplied by 10% that gives u 2 which u then add onto the 20 to get the starting price. 10% of 22 is 2 and then 22-2 = 20 (if u we’re doing it from the starting price)
