What's the surface area for this?​

Answers

Answer:

382

Step-by-step explanation:

Surface area = 2(7 × 8) + 2(7 × 9) + 2(8 × 9)

                      = 382

Answer:

SA=382

Steps:

SA=2(7×8)+2(7×9)+2(8×9)

SA=2×56+2×63+2×72

SA=112+126+144

SA=382

The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x. The price p in dollars that the company can charge for the product is given by p(x) = x + 5. Use the formula Revenue = price × demand to find the revenue function for the product.


R(x) = ________ + ________ x – _______ x^2

Answers

Answer:

-2x²+490x+2500

Step-by-step explanation:

Given that,

Demand, D(x) = 500-2x

The price for the product, P(x) = x+5

We need to find the revenue for the product. The formula for the revenue is given by :

Revenue = price × demand

Substitute all the values,

R = (x+5)(500-2x)

= 500x -2x² + 2500 -10x

= -2x²+490x+2500

So, the expression for the revenue function is "-2x²+490x+2500".

divide 405 in the ratio 4:11​

Step-by-step explanation:

Answer is in the photo

Hope it helllps

Good luck

The division of the number 405 in the ratio 4:11 is 297 and 108 respectively.

What are ratios and proportions?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that the ratio is 4:11. the number is 405 which has to be divided by the ratio.

Let the common ratio between the numbers is x. Form an equation and solve for x.

4x + 11x = 405

15x = 405

x = 405 / 15

x = 27

The numbers are,

4x = ( 4 x 27 ) = 108

11x = ( 11 x 27 ) = 297

Therefore, the division of the number 405 in the ratio 4:11 is 297 and 108 respectively.

Which function is equivalent to g(x) = x2 + 15x – 54?
g(x) = (x + 9)(x – 6)

g(x) = (x – 9)(x + 6)

g(x) = (x – 18)(x + 3)

g(x) = (x + 18)(x – 3)

Answers

Answer:

g(x)=(x+18)+(x-3)

Step-by-step explanation:

The function i.e. g(x)=(x+18)(x-3) equivalent to the given equation.

Given that,

The equation is [tex]g(x) = x^2 + 15x - 54[/tex].We need to solve it.

Based on the above information, the calculation is as follows:
