Timmy is helping his grandpa on his chicken farm. Timmy has to pack 66 eggs into cartons, minimizing the packing cost. He can use 12-egg cartons and 6-egg cartons. Two 12-egg cartons cost as much as three 6-egg cartons.

Answers

The way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.

Since Timmy is helping his grandpa on his chicken farm, and he has to pack 66 eggs into cartons, minimizing the packing cost, and he can use 12-egg cartons and 6-egg cartons, and two 12-egg cartons cost as much as three 6-egg cartons, to determine how many cartons of each should be used, the following calculation must be performed:

2 x 12 = 3 x 6 24 = 18 Thus, assuming as an example that a total of 2 cartons of 12 eggs and 3 cartons of 6 eggs cost $ 3, the value of each carton would be the following: 3/3 = 1 3/2 = 1.5  66/12 = 5.5 5 x 1.5 + 1 x 1 = X 7.5 + 1 = X 8.5 = X

In this way, the way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.

Show that f(x)=12x^3-32x^2+17 has a zero between 2 and 3.

Answers

Answer:

Step-by-step explanation:

You could graph it. I'll do that at the bottom. What you need is a value that is - on either 2 or 3 and a plus on the other one.

y=12*2^3 - 32x^2 + 17

y = 12 * 8 - 32*2^2 + 17

y = 96 - 128 + 17

y = -15

Now when x = 3 should give you something above the x axis

y = 12*3^3 - 32*9 + 17

y = 324 - 288 + 17

y = 53

What this indicates is that somewhere between 2 and 3 the graph crosses the x axis. The graph should indication that.

Answers

Answer:

Angle B is 52 degrees

Step-by-step explanation:

The outer angle 112 adds up with the inner angle to make 180. So angle C is 68. All the angles should add up to 180, so add them all together.

68+4y+3y+7 = 180

75+7y = 180

7y = 105

y = 15

To double-check this, plug 15 into y and add up all the angles, it should add up to 180.

3(15)+7 = 52

4(15) = 60

68+60+52 = 180

Answer:

  (A) -4 and -2

Step-by-step explanation:

The constant in the function tells you f(0) = 5.

You know that the positive leading coefficient means the value of f(x) will be negative for x-values smaller than some number. The offered answer choices indicate the value x = -4 is a lower bound on the value of c. So, -4 < c < 0, for sure.

To further refine the interval, you would need to know f(-2) and/or f(-1).

  f(-2) = (-2)³ -2(-2) +5 = -8 +4 +5 = 1

Then -4 < c < -2.

If g(x)=3x-2, find g(3)-g(-8)

Answers

Answer:

33

Step-by-step explanation:

1. Let's solve for g(3)

Step 1: Plug in the value of x.

[tex]g(3)=3(3)-2[/tex]

Step 2: Simplify.

[tex]g(3)=9-2[/tex] [tex]g(3)=7[/tex]

2. Let's solve for g(-8)

Step 1: Plug in the value of x.

[tex]g(-8) = 3(-8)-2[/tex]

Step 2: Simplify.

[tex]g(-8) = -24 - 2[/tex] [tex]g(-8)=-26[/tex]

3. Now, let's subtract g(-8) from g(3).

[tex]g(3)-g(-8)[/tex] [tex](7)-(-26)[/tex] [tex]7+26[/tex] [tex]33[/tex]

Therefore, the answer is 33.

Answer:

33

Step-by-step explanation:

g(x) = 3x - 2

g(3) = when x of g(x) function is 3.

g(3) = 3(3) - 2

g(3) = 9 - 2

g(3) = 7

g(-8) = 3(-8) - 2

g(-8) = -24 - 2

g(-8) = -26

g(3) - g(-8)
