Pete corporation produces bags of peanuts. It's fixed cost is $18,900. Each bag sells for $2.17 with a unit cost of $1.27. What

pentagon [3]

Answer:

in units: 18,900

in dollars: $ 41,013

Step-by-step explanation:

The break even point is the sales dollar amount or sales in unit at whichthe operating income of the firm equals to zero: $\frac{Fixed\:Cost}{Contribution \:Margin} = Break\: Even\: Point_{units }$

Where:

$\frac{Contribution \: Margin}{Sales \: Revenue} = Contribution \: Margin \: Ratio$

Contribution margin:

2.17 - 1.27 = 1 dollar per unit

Break even:

$18,900 fixed cost / $1 per unit = 18,900 units

Then, in sales:

18,900 x $2.17 each = 41.013‬

break even point:

Which of the following shows that polynomials are closed under subtraction when polynomial x + 5 is subtracted from 3x2 + 2x − 6

Art [367]

For this case we have the following polynomials:
$P = 3x ^ 2 + 2x - 6

Q = x + 5$
By subtracting both polynomials we have:
$P - Q = (3x ^ 2 + 2x - 6) - (x + 5)
$
What we must do is subtract terms of the same degree.
We have then:
$P - Q = 3x ^ 2 + (2x - x) + (-6 - 5)

P - Q = 3x ^ 2 + x - 11$
Answer:
$3x ^ 2 + x - 11$ will be a polynomial

The graph of an exponential function passes through the point (0,15) and (1,10). What is the equation of the exponential functio

Vilka [71]

Answer:

$y=15(\frac{2}{3})^x$

Step-by-step explanation:

we know that

The equation of a exponential function is of the form

$y=a(b^x)$

where

a is the initial value or y-intercept

b is the base of the exponential function

In this problem we have

$a=15$ ----> the y-intercept is given

substitute

$y=15(b^x)$

we have the other ordered pair (1,10)

substitute the value of x and the value of y and solve for b

$10=15(b^1)\\10=15b$

$b=\frac{10}{15}=\frac{2}{3}$

substitute

$y=15(\frac{2}{3})^x$

see the attached figure to better understand the problem

2) A circle has a radius of 8 cm. What is its circumference? 8 cm

egoroff_w [7]

Answer

16π cm ≈ 50.2655 cm

Step-by-step explanation

To find the circumference of a circle, we can use the equation C = 2πr.

C stands for the circumference while r stands for the radius. We can see that there is a proportional positive linear relationship between radius and circumference for all circles, and that to find circumference when we have a radius value, we multiply the radius value by 2π.

The value of π, also called pi, is a constant and is the ratio of a circle's circumference to its diameter (the diameter is twice the radius, hence the 2 in the equation). Note that π is a constant and applies to all circles because all circles are similar.

Since we know the value of r, or the radius, given as 8 cm in the question, we can plug this value into the equation C = 2πr from earlier.

C = 2πr (plug in 8 cm for the radius)

C = 2π * 8

C = 16π cm

Since the radius is in units of cm (centimeters), the circumference is also in units of cm (centimeters).

16π cm is the exact value of the circumference. However, if we want this circumference in decimal form, we would multiply 16 by the decimal form of π which is approximately 3.1416. Note that π actually has an infinite amount of decimals and that this 3.1416 is actually a rounded π value

C = 16π

C ≈ 16 * 3.1416

C ≈ 50.2655 cm rounded to four decimal places
