Answers

Answer:

x^2 -1 - 5(x-1)

Step-by-step explanation:

p(x) = x^2 - 1 and q(x) = 5(x - 1)

p(x) - q(x) = x^2 - 1 - ( 5(x-1))

               Distribute

Find the volume of the cylinder. Find the volume of a cylinder with the same radius and double the height.

The volume of the cylinder is ?

The volume of a cylinder with the same radius and double the height is ?

Answers

Answer:

Step-by-step explanation:

The volume of the original cylinder = pi * r^2 * h

Givens

r = 6 in

h = 3 in

pi = 3.14

Solution

V = pi * r^2 * h

V = 3.14 * 6^2* 3

V = 3.14 * 36 * 3

V = 339. 12

Part 2

If you double the height, you will double the volume

V = 3.14 * 36 * 6

V = 678.24

What is the perimeter of a rectangle?

The perimeter of a rectangle of length l and width w is given by:

What is the slope of a line that is perpendicular to the
graph of y=1/6x+8 ?
Select one:
-6

6

1/6

-1/6

Answers

Answer:

A. -6

Step-by-step explanation:

The slope of the line that is perpendicular to the graph y = ⅙x + 8, is a negative reciprocal of the slope of the graph, y = ⅙x + 8.

What this means is that, if you multiply the slope of y = ⅙x + 8, and the slope of the line perpendicular to it, you would have -1. That is [tex] m_1 * m_2 = -1 [/tex].

Where,

[tex] m_1 [/tex] = slope of y = ⅙x + 8.

[tex] m_2 [/tex] = slope of the line perdendicular to y = ⅙x + 8.

The slope of y = ⅙x + 8 is ⅙.

Substitute [tex] m_1 [/tex] = ⅙ into [tex] m_1 * m_2 = -1 [/tex], to find the slope [tex] (m_2) [/tex] of the line that is perpendicular to the graph of y = ⅙x + 8.

[tex] \frac{1}{6} * m_2 = -1 [/tex]

Multiply both sides by 6

[tex] \frac{1}{6} * m_2 * 6 = -1*6 [/tex]

[tex] 1*m_2 = -6 [/tex]

[tex] m_2 = -6 [/tex]

The slope of the line that is perpendicular to the graph of y = ⅙x + 8 is -6.

Statins are used to keep cholesterol in check and are a top-selling drug in the U.S. The equation: S − 1.9 x = 4.9 gives the amount of sales ( S ) of statin in billions of dollars x years after 1998. According to this equation, how much will/did people in the U.S. Spend on statins in the year 2005? Answer: People in the U.S. Will spend billion dollars on statins in 2005.

Answers

Answer:

People in the U.S. Will spend 18.2 billion dollars on statins in 2005.

Step-by-step explanation:

Given:

S − 1.9x = 4.9

Where,

S = sales of statin in billions of dollars

x = years after 1998

how much will/did people in the U.S. Spend on statins in the year 2005?

2005 is a year after 1998

Number of years = 2005 - 1998

= 7

x = 7 years

S − 1.9x = 4.9

S - 1.9(7) = 4.9

S - 13.3 = 4.9

Add 13.3 to both sides

S = 4.9 + 13.3

= 18.2

People in the U.S. Will spend 18.2 billion dollars on statins in 2005.

Sally works in a cell phone store. She is paid a weekly salary of $80 plus $5.25 for each cell phone she sells. Which equation can be used to find Sally's total weekly income?


F- y = 5.25x + 80

G- y = 80x +5.25

H- y = 85.25x

J- Not here

Answers

First, let's define some variables.

x = # of cell phones sold.

y = total weekly income.

y = $5.25x + $80

F is the correct answer choice.

If $80 is her standard income per week, then there is no variation in how much shes earning for that chunk of money. The phones however are $5.25 per phone shes sold, and that exact number could vary, so we’d represent that with “x.” the correct equation to solve this would be y(total weekly income)= $5.25x + 80

On factorization of the equation x² − x − 6 = 0. Then the values of x are −2 and 3.

What is a factorization?

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The equation is given below.

x² − x − 6 = 0

On factorization, we have

 x² − 3x + 2x − 6 = 0

x(x − 3) + 2(x − 3) = 0

       (x − 3)(x + 2) = 0

Step-by-step explanation:

Before finding the area of the circle, first, let us find the radius.

d = 2r

14 = 2r

Divide both sides by 2.

7 in = r

And now let us find the area of the circle.

Area = π r²

        = 3.14 × 7 × 7

        =  21.98 × 7
