A company’s profit in dollars is modeled by the equation p(x) = –0.5x2 + 100x, where x represents the number of units sold.
serg [7]

Answers:

a. The company needs to sell 100 units to reach the maxmum profit.

b. The company's maximum profit is $5,000.

Solution:

a. How many unit does the company need to sell to reach the maximum profit?

p(x)=-0.5x^2+100x

This is a quadratic equation, and its graph is a parabola vertical (because the veriable "x" is square). Comparing with the general form:

p(x)=ax^2+bx+c; a=-0.5, b=100, c=0

a=-0.5<0 (negative), then the parabola opens downward, and it has a maximimun value (maximum profit) at its vertex.

We can find the abscissa of the vertex (units that the company needs to sell to reach the maximum profit using the following formula:

x=-b/(2a)

Replacing b by 100 and a by -0.5 in the formula above:

x=-100/[2(-0.5)]

x=-100/(-1)

x=100

The company needs to sell 100 units to reach the maximum profit.


b. What's the company's maximum profit?  

To determine the maximum profit we substitute the value of "x" obrained in part "a" in the quadratic equation:

x=100→p(100)=-0.5(100)^2+100(100)

p(100)=-0.5(10,000)+10,000

p(100)=-5,000+10,000

p(100)=5,000

The company's maximum profit is $5,000.

The interest she would pay is $694.40.

<h3>What is simple interest?</h3>

Simple interest rate is the interest that is paid only on the principal portion of a loan. This means that the debtor does not pays interest on the interest rate already accrued.

<h3>What interest does she pay? </h3>

Simple interest = principal x time x interest rate

$6200 x 4 x 0.028 =  $694.40.

Using this formula l=A 1/2 what is the length of one side of a square with an area of 1,936 square kilometers? (A is the area of
Vera_Pavlovna [14]

<u>c.)44 kilometers</u>

Answer:

Solution given:

let

length =L

and

Area =A

Now

we have

Area [A]=1936 square kilometers

now

As we know that

Area of square :length *length

A=l*l

A=l²

Substituting value of A

1936=l²

doing square root on both side

\sqrt{1936}=\sqrt{l²}

we get

l=\sqrt{2*2*2*2*11*11}

l=2*2*11

l=44 kilometers

So

<u>the length of one side of a </u><u>square</u><u> </u><u>is</u><u> </u><u>4</u><u>4</u><u> </u><u>kilometers</u><u>.</u><u />

The surface area, A, of a cylinder is given by the formula A = 2 Trh + 2nr, where ris the radius and h is the height
lord [1]

Answer:

Area = 87.9646  sq. units  from A = 28*π  sq. units.

However I cannot see this in your answer list, since the numbers look all jumbled.  Choice A. looks close to it, since there is a 28...

Step-by-step explanation:

We have a cylinder with height h = 5

radius = 2

We want the surface area of this cylinder.

A = (circumference)*h  + 2*(pi)*r^2

A = ( 4*π)*5   + 2*π*(2^2)

A = 20π + 8π  =  28 π   square units

A = 87.9646 sq.. units
