Step-by-step explanation:

use FOIL (first, outside, inside, last)

(2x-1)(-x+2)

2x(-x)=-2x^2

2x(2)=4x

-1(-x)=x

-1(2)=-2

What is the volume of a cylinder, in cubic ft, with a height of 9ft and a base diameter

aev [14]

Answer:

Volume of cylinder is: Volume=1808.64 ft³

Step-by-step explanation:

Height of cylinder = 9 ft

Base diameter of cylinder = 16 ft

We need to find volume of cylinder .

The formula used is: $Volume=\pi r^2h$

We need radius:

The radius = diameter/2 = 16/2 = 8 ft

Putting values and finding volume of cylinder

$Volume=\pi r^2h$

$Volume=3.14\times (8)^2\times (9) \\Volume=3.14\times 64\times (9) \\Volume=1808.64 \: ft^3$

So, Volume of cylinder is: Volume=1808.64 ft³

What is a solution for both equations y=x+3 and -2x+y=1

Soloha48 [4]

Answer:

(2, 5)

Step-by-step explanation:

Given the 2 equations

y = x + 3 → (1)

- 2x + y = 1 → (2)

Substitute y = x + 3 into (2)

- 2x + x + 3 = 1

- x + 3 = 1 ( subtract 3 from both sides )

- x = - 2 ( multiply both sides by - 1 )

x = 2

Substitute x = 2 into (1) for corresponding value of y

y = 2 + 3 = 5

Solution is (2, 5)

6. Parker, Inc. used Excel to run a least-squares regression analysis, which resulted in the following output: Regression Statis

aleksley [76]

Answer:

"34,814" is the correct solution.

Step-by-step explanation:

The given values are:

Intercept coefficient,

$\beta_0 = 23,859$

Production coefficient,

$\beta_1 = 3.13$

Units sold,

x = 3,500

Now,

The total cost will be:

⇒ $\bar{y}=\beta_0+\beta_1 x$

On substituting the estimated values, we get

⇒ $=23,859+3.13\times 3,500$

⇒ $=23,859+10,955$

⇒ $=34,814$
