A store uses the expression –2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere from $9 to $15. Which price gives the store the maximum amount of revenue, and what is the maximum revenue? (Revenue = price x number of backpacks.)

A. $9.00 per backpack gives the maximum revenue; the maximum revenue is $32.00.
B. $12.00 per backpack gives the maximum revenue; the maximum revenue is $312.00.
C. $12.50 per backpack gives the maximum revenue; the maximum revenue is $312.50.
D. $15.00 per backpack gives the maximum revenue; the maximum revenue is $20.00.

Answers

Letter C has the highest revenue so we will just have to check if it is correct.

-2(12.50)+50 = 25
Revenue = price x number of backpacks
Revenue = 25 x $12.50
Revenue = $312.50

So, letter C is the correct answer.

Answer:

$12.50 per backpack gives the maximum revenue; the maximum revenue is $312.50.

Which is the best definition of the radius of a circle? A. The distance around the outside of the circle
B. The distance across the middle of the circle
C. The Point at the center of the circle
D. The distance from the center to any point on the circle

Answers

The best definition of the radius of a circle is option D: "The distance from the center to any point on the circle."

The radius is a fundamental geometric concept that is integral to understanding and describing circles. It is a straight line segment that extends from the center of the circle to its outer edge.

This single measurement defines the size of the circle and is consistent from the center to any point on the circumference. It is crucial in various mathematical and geometric calculations, including calculating the circle's area, circumference, and relationships with other elements in geometry. Option D succinctly encapsulates the essence of the radius and its geometric significance in a clear and concise manner.

A surveyor find that the cross section of the bottom of a circular pound has the shape of a parabola. The pond is 24 feet in diameter. The middle of the pond is the deepest part at 8 feet deep. At a point 2 feet from shore the water is 3 feet deep. How deep is the pond at a point 6 feet from shore?

Answers

Answer:

2.32 feet

Step-by-step explanation:

Given;

The cross section of the bottom of a circular pound has the shape of a parabola

Now,

For the circular parabola, the equation is given as:

y² = 4ax

here,

y is the depth

x is the horizontal distance from the center

a is the constant

also,

at diameter of the pond = 24 feet

and,

at x = 0 ; y = 8 feet

now,

the point 2 feet from the shore with respect to the center of the pond = radius of the pond - The distance from the shore

= $\frac{\textup{24}}{\textup{2}}$ - 2 = 10 feet

thus,

at x = 10 feet ; y = 3 feet

thus,

we have

the equation as:

3² = 4a × 10

0.9 = 4a

a = 0.225

therefore,

we get the equation as;

y² = ( 4 × 0.225 ) × x

and, for point 6 feet away from the shore, i.e $\frac{\textup{24}}{\textup{2}}$ - 6 = 6 feet away from the center

we have

y² = ( 4 × 0.225 ) × 6

y² = 5.4

y = 2.32 feet (negative value is neglected as the depth cannot be negative)

Simplify 1/4(8m - 4n) + 1/3(6m + 3n)

Answers

Answer:

The simplified of $(1)/(4)(8m-4n)+ (1)/(3)(6m+3n)$ is 4m .

Step-by-step explanation:

As given

$= (1)/(4)(8m-4n)+ (1)/(3)(6m+3n)$

L.C.M of (4,3) = 12

$= (3* (8m-4n)+4* (6m+3n))/(12)$

$= (3* 8m-3* 4n+4* 6m+4* 3n))/(12)$

$= (24m-12n+24m+12n)/(12)$

$= (24m+24m)/(12)$

$= (48m)/(12)$

= 4m

Therefore the simplified of $(1)/(4)(8m-4n)+ (1)/(3)(6m+3n)$ is 4m .

1/4(8m - 4n) + 1/3(6m + 3n)=

Distribute the fractions through the parentheses

2m - n + 2m + n =

Combine like terms

2m + 2m - n + n = 4m

Simplified Answer is 4m

Explain how the position of the decimal point changes in a quotient as you divide by increasing powers of ten.

Answers

When you divide by increasing powers of ten, the decimal moves one digit to the left.

Example:
1/10=0.1
1/100=0.01
1/1000=0.001

As the powers of ten increases, the decimal moves to the left.

each time you times a number with a decimal point by 10 the point will move to right one space
