The Lotta Chocolate Factory makes CHEWY CHERRY CHOCOLATES. The chocolates are shipped out in cases. Each case contains 9 boxes.

babunello [35]

Answer:

324

Step-by-step explanation:

One case has 9 boxes.

One box has 36 chocolates.

This equation would answer the amount in a case, case = chocolate*boxes

So there would be 36*9 chocolates, and that equals 324 in one case

I turn my dial on my stove 45degrees from the start position if i continue to turn the dial, how many degrees further will i nww

AveGali [126]

Answer:

315 degrees

Step-by-step explanation:

Assume that the dial is a perfect circle and therefore makes a full 360 degree rotation. If the dial is already turned 45 degrees, the rotation angle required to return all the way to the initial position is:

$A = 360 - 45\\A=315\ degrees$

You will need to rotate 315 degrees.

Suppose you have entered 115-mile biathlon that consists of a run and a bicycle race. During your run, your average velocity is

Maksim231197 [3]

Answer:

The distance of the run was 27 miles and the distance of the bicycle race was 88 miles.

Step-by-step explanation:

Since I have entered 115-mile biathlon that consists of a run and a bicycle race, and during my run, my average velocity is 9 miles per hour, and during my bicycle race, my average velocity is 22 miles per hour , and I finish the race in 7 hours, to determine what is the distance of the run and what is the distance of the bicycle race, the following calculations must be performed:

7 x 22 + 0 x 9 = 154

5 x 22 + 2 x 9 = 128

4 x 22 + 3 x 9 = 115

Therefore, the distance of the run was 27 miles and the distance of the bicycle race was 88 miles.

Find a formula for the given polynomial.

levacccp [35]

In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:

$p(x) = -0.5(x^3 - x^2 + 6x)$

------------------------

Equation of a polynomial, according to it's zeros:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

------------------------

Identifying the zeros:

Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:

$x_1 = -2, x_2 = 0, x_3 = 3$

Thus

$p(x) = a(x - x_{1})(x - x_{2})(x-x_3)$

$p(x) = a(x - (-2))(x - 0)(x-3)$

$p(x) = ax(x+2)(x-3)$

$p(x) = ax(x^2 - x + 6)$

$p(x) = a(x^3 - x^2 + 6x)$

------------------------

Leading coefficient:

Passes through point (2,-8), that is, when $x = 2, y = -8$ , which is used to find a. So

$p(x) = a(x^3 - x^2 + 6x)$

$-8 = a(2^3 - 2^2 + 6*2)$

$16a = -8$

$a = -\frac{8}{16} = -0.5$

------------------------

Considering the zeros and the leading coefficient, the formula is:

$p(x) = -0.5(x^3 - x^2 + 6x)$
