Answer:

Step-by-step explanation:

22/25

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.

Answer:

25 degrees

Step-by-step explanation:

The computation is shown below:

24°59'60" = 24°+59'+60"

Now

As we know that

1'=60"

i.e. (1 minute = 60 seconds)

so,

24°+59'+60" = 24°+59'+1'

=24°+60'

Also,

1°=60'(1 degree=60 seconds)

= 24°+1°

=25°

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

                              =    408,074.4 cm³       < -----------------   Final Answer

Answer:

1.  d = 2t

2. d = 2 (13)     d = 26 meters

3. I added the graph in a file

Answer:

the second and first steps. in the second part, x, should be substracted by x

so no xz should remain in the second part of the equation.

the second step would be:

6x - 5 = 7

Answer:

-64a^13 :)

I hope this helped you a bit!

Step-by-step explanation:

Apply the product rule to 4a^3.

-4^3 (a^3)

Raise -4 to the power of 3.

-64 (a^3)^3*a^4

Multiply the exponents in (a^3)^3.

Apply the power rule and multiply exponents

-64a^3*3*a^4

Multiply 3 by 3.

-64a^9*a^4

Multiply

a^9

by a^4

by adding the exponents.

Move a^4

-64 (a^4 a^9)

Use the power rule to combine exponents

-64a^4+9

Add 4 and 9.

-64a^13

Answer:

LCM: 1,800

GCF: 150

Step-by-step explanation:

150:600 = 150 / 600 = 0.25 (that's pretty much what a ratio is, just a fraction or part of a whole.)

150 is the greatest common number that will factor into all three, and the least/smallest number they all multiply into is 1,800

[tex] \huge \boxed{ \boxed{ {(x - 2)}^{2} }}[/tex]

Step-by-step explanation:

and

we are done

Answer:

D) b/a

From the given figure, O = (0, 0) and A = (a, b)

Slope of OA = (y2 - y1) / (x2 - x1)

Here x1 = 0, y1 = 0, x2 = a and y2 = b.

Slope of OA = (b - 0)/(a - 0)

Slope of OA = b/a

Answer: D) b/a

The converted units is 120 pounds = 54.5 kilogram

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

Answer:

a. 10%

b. 37.57

c. What the coin was worth 3 years prior to 2000

Step-by-step explanation:

a. The equation for exponential growth is v(t) = P(1+r)^t. Where v(t) is the total amount, P is the principal, r is the rate of growth, and t is time in years. For part a, you need to find r, the rate. In this situation, r is equal to .1, which is equal to 10%.

b. To find part b simply solve the equation for when t equals -3. So the equation should look like [tex]v(t)=50(1.1)^{-3}[/tex]. When this is plugged into a calculator or solved by hand the total equals $37.57.

c. In this, t equals the time in years since 2000. Since -3 is negative, this must take place 3 years before 2000. Therefore, v(-3) must represent the value of the coin in 1997.

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

Answer:

-1/2

Step-by-step explanation:

Answer:

y = -1/2x + 1

Step-by-step explanation:

(0,1) and (2,0)

Slope:

m=(y2-y1)/(x2-x1)

m=(0-1)/(2-0)

m=(-1)/2

m= -1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 1 = -1/2(x - 0)

y - 1 = -1/2x

y = -1/2x + 1
