PLEASE HELPPPPP
The revenue made by a car
company from the sale of y cars is given by 0.003y! +
10y. The cost to produce y cars is given by the polynomial 20y + 1,000,000. Write
a polynomial expression for the profit from making and selling y cars. Find the
profit the company will make if it sells 30,000 cars.

Answers

Answer:

Part A

The polynomial expression for the profit from selling and making 'y' cars is 0.003·y² - 10·y - 1,000,000

Part B

The profit made from selling 30,000 cars is 1,670,000

Step-by-step explanation:

Part A

Taking the revenue, 'R', made by the car company for the sale of 'y' cars as R = 0.003·y² + 10·y

The cost to produce 'y' cars, C = 20·y + 1,000,00

The profit, 'P', from making and selling 'y' cars is given as follows;

P = R - C

∴ 0.003·y² + 10·y - (20·y + 1,000,00) = 0.003·y² - 10·y - 1,000,00

An expression of the polynomial for the profit 'P', from selling and making 'y' cars is therefore presented as follows;

0.003·y² - 10·y - 1,000,000

Part B

The profit made from selling 30,000 cars, (y = 30,000) is given as follows;

= 0.003·y² - 10·y - 1,000,000

[tex]P_{y = 30,000}[/tex] = 0.003 × 30,000,000² - 10×3,000 - 1,000,000 = 1,670,000

The profit made from selling 30,000 cars = 1,670,000.

A highway is going to be built around a city. The highway will be in the shape of a perfect circle, and its total length will be 251.2 kilometers. A nearby bus stop will have a billboard with a map of the bus routes along the highway. The map is drawn to a scale of 1:7,500. Calculate the area that is surrounded by the highway on the billboard map. Round the answer to the nearest hundredth of a square meter.

Answers

Answer:

The area that is surrounded by the highway on the billboard is approximately 89.34 square meters

Step-by-step explanation:

The given parameters are;

The length of the circle shaped highway = 251.2 km

The scale of the map of the bus routes along the highway = 1:7,500

The circumference of a circle, C = 2·π·r = The length of the perimeter of the circle

Therefore, we have;

The circumference of the highway = The length of the circle shaped highway = 251.2 km

The circumference of the highway, C = 251.2 km = 2·π·r

The radius of the circular highway path, r = 251.2 km/(2·π) ≈ 39.994217 km

The area of a circle, A = π·r².

The area of the highway = π·r² = π × (39.994217 km)² ≈ 5,025.09492434 km.²

Given that the scale of the map = 1:7,500. we have;

The scale of the area = (1:7,500)² = (1:56,250,000)

The size of the drawing, 5,025.09492434 km.²/(56,250,000) = 0.00008933502 km² = 89.33502 m.²

Therefore, the area that is surrounded by the highway on the billboard, rounded to the nearest hundredth of a square meter ≈ 89.34 m.²

account with a fixed annual interest rate of
3% compounded continuously. What will
the account balance be after 17 years?

Answers

Answer:

$3828 approx

Step-by-step explanation:

Given data

Principal=$2316

Rate= 3%

Time= 17 years

The compound interest formula is

A=P(1+r)^t

substitute

A=2316(1+0.03)^17

A=2316(1.03)^17

A=2316*1.652847

A=$3827.99

Hence the account balance after 17 years is $3828 approx

Use ​ ≈ 3.14. Do not round your answer.

Answers

Answer:

Step-by-step explanation:

area of a cylinder = (area of a circle) times the (height)

area of a cylinder = π radius² × height

            radius = 57 cm        height = 40 cm

area of a cylinder  =   π 57² cm² × 40 cm

                              =   π (57² × 40) cm³

                              =   π ( 57 × 57 × 40) cm³             57x57 = 399 + 2850 = 3249  

                              =   π (3249 × 40) cm³

                              =    129969π cm³      π = 3.14

                              =    129969 × 3.14  cm³

100:88 = x:600

100/88=x/600

100/88 ×600 = x

Explain how to use the unit-factor method to convert 120 pounds to kilograms.

Hint: 1 kilogram=2.2 pounds

To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.

Answers

The converted units is 120 pounds = 54.5 kilogram

How to convert the units?

As a general rule, we have:

1 kilogram=2.2 pounds

Multiply both sides by 120

120 * 1 kilogram=2.2 pounds * 120

Divide both sides by 2.2

120/2.2 * 1 kilogram=2.2 pounds * 120/2.2

Evaluate the products

54.5 kilogram= 120 pounds

Rewrite as:

120 pounds = 54.5 kilogram

Hence, the converted units is 120 pounds = 54.5 kilogram

A circular plate has circumference 32 inches. What is the area of this​ plate? Use 3.14 for pi. The area of this plate is about nothing square inches.

Answers

Answer: The area of the plate is 81.67 in^2

Step-by-step explanation:

If we have a circle of radius R, the area of this circle can be computed as:

A = pi*R^2

where pi = 3.14

And the circumference is:

C = 2*pi*R

and we know that this is equal to 32 in, then:

32in = 2*pi*R

Now we can isolate R, and we get:

32in/(2*pi) = R

32in/(2*3.14) = R = 5.1 in

Then the area of the plate is:

A = 3.14*(5.1in)^2 = 81.67 in^2
