Answer:

The quality control facility operates for 10 hours each day.

Step-by-step explanation:

The given function models the number of cars that are put through a quality control test each hour at a car production factory.

The given function is

We need to find the number of hours does the quality control facility operate each day.

Rewrite the given function it factored form.

Taking out the common factors from each parenthesis.

The factored form of given function is c(t)=-(t-10)(t+2).

Equate the function equal to 0 to find the x-intercept.

Number of hours cannot be negative. So from t=0 to t=10 quality control facility operate the cars.

11x + 2y = 68 & 5x + y = 13
matrenka [14]

Answer:

i hope its correct

Step-by-step explanation:

11x + 2y=68 ------------1

5x+y=13 ------------2

y= 13-5x. ------------3

put 3 into 1

11x +2(13-5x) =68

11x +26 -10x =68

x=42

put x =42 into 2

5(42) +y =13

210+y=13

y=13-210

y=197

Part A: A graph passes through the points (0, 2), (2,6), and (3. 12). Does this graph represent a linear
allsm [11]

Answer:

The function given is non-linear.

Step-by-step explanation:

The slope between (0, 2) and (2,6):

\frac{6-2}{2-0}=\frac{4}{2}=\boxed{2}

The slope between (2,6), and (3, 12):

\frac{12-6}{3-2}=\frac{6}{1}=\boxed{6}

Since the slopes are not equal to each other, the function is non-linear. A linear function's slope must stay consistent.

Hope this helps.

How do you rewrite p(x)=-5x2+120x-315 in vertex form
True [87]

Answer:

p(x)=-5(x-12)^2+405

Step-by-step explanation:

Hi there!

Vertex form: f(x)=a(x-h)^2+k

p(x)=-5x^2+120x-315

Factor out -5 from the first two terms

p(x)=-5(x^2-24x)-315

Complete the square by adding (\frac{24}{2} )^2 (the square of half of the x-coefficient)

p(x)=-5(x^2-24x+(\frac{24}{2} )^2)-315-(-5)(\frac{24}{2} )^2

We're subtracting (-5)(\frac{24}{2} )^2 because we need to keep the equation balanced and we can't just add new values.

Complete the square

p(x)=-5(x-(\frac{24}{2} ))^2-315-(-5)(\frac{24}{2} )^2

Simplify

p(x)=-5(x-12)^2-315+720\\p(x)=-5(x-12)^2+405

Summary:

  1. Complete the square
  2. Simplify

I hope this helps!
