If P(x) = -2(1 - x)2 +5, what is the value of
P(-3)?

Answers

Answer:

P(-3) = -1

Step-by-step explanation:

So just substitute the value of x in the equation:

Value of x is (-3)

So:

P(x) = -2(1 - x)2 +5

P(-3) = -2(1-(-3)) 2 + 5

P(-3) = -2(4) 2 + 5

P(-3) = -8 + 2 + 5

P(-3) = -6 + 5

P(-3) = -1

My restaurant budget should not go over $100. If I bought main dish for $50 and $12 for each pizza, how many pizza's can I buy?

inequality :
50 + 12x ≤ 100

How many pizza's can I buy?

Answers

Answer:

x = 25

Step-by-step explanation:

50 + 12x <_ 100

12x <_ 100 - 50

12x <_ 50

x <_ 50 / 12

x <_ 25

You can buy about 4 pizzas.

I didn't use the way that I probably should have but you can subtract 50 from 100 and then divide the 50 by 12 and you will get 4.1666667.

Use the following picture to find the measure of angles 3 and 4. (picture)

Answers

The measure of angle 3 is 180-110=70 because of supplementary angles. Angle 2 would be 180-80=100, again because of supplementary angles. Finally, angle 4 is equal to 180-angle 2 which is 180-100 which is 80 (Supplementary angles again). So the answer would be the second option.
3=70, 4=80

Answer:

The mode is 78, for it keeps repeating.

A construction company produces two products (doors and windows) that require two plants (A and B). Management wants to determine how many units of each product should be produced to maximize profit. For each unit of Product 1 (i.E. Door), 2 workers are required in Plant A and 4 workers are required in Plant B. For each unit of Product 2 (i.E. Window), 3 workers are required in Plant A and 4 workers are required in plant B. The company has 40 workers in Plant A and 60 workers in Plant B. Each unit of Product 1 gives a profit of $100. Each unit of Product 2, up to 10 units, gives a profit of $80. Any excess over 10 units of Product 2 brings no profit; so, such excess has to be ruled out.

Z max = 1500

x₁ = 15

x₂ = 0

Step-by-step explanation:

From problem statement:

Plant A Plant B Profit $/each

Product 1 (Doors ) x₁ 2 4 100

Product 2 (windows ) x₂ 3 4 80

Product 2 (windows ) x₂ above 10 is scrap

Objective function to maximize

z = 100*x₁ + 80*x₂

Subject to:

Plant A capacity

2*x₁ + 3*x₂ ≤ 40

Plant B capacity

4*x₁ + 4*x₂ ≤ 60

Windows condition:

0*x₁ + x₂ ≤ 10

Model:

Max z = 100*x₁ + 80*x₂

Subject to:

2*x₁ + 3*x₂ ≤ 40

4*x₁ + 4*x₂ ≤ 60

x₂ ≤ 10

Jenna borrowed $5,000 for 3 years and had to pay $1,350

simple interest at the end of that time. What rate of interest

did she pay?

Answers

Answer:

0.09 or 9%

Step-by-step explanation:

Formula:

I = Prt

r = I/(Pt)

Given:

I = 1350

P = 5000

t = 3

Finding r:

r = I/(Pt)

r = 1350/(5000 x 3)

r = 1350/15000

r = 0.09

0.09 or 9%

Answer:

A. Reduction

B. 2

Step-by-step explanation:

A: A reduction is when the image is getting smaller. The apostrophes show the new, or second, image. It is called "prime." Because the prime is smaller than the original, it is a reduction.

B: Scale factor is when you divide, which number changes it. In other words, the image moved from 4 to 2, from 2 to 1, etc, which means we are DIVIDING by 2.
