HELP!! WHAT IS THE SURFACE AREA OF THIS?

Radius = 14 : 2 = 7 in.

Area = 7 x 7 x 3.14 = 153.86 (in2)

Answer:

153.86 in²

Step-by-step explanation:

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

14 = 2r

Divide both sides by 2.

7 in = r

And now let us find the area of the circle.

        = 3.14 × 7 × 7

        =  21.98 × 7

        =  153.86 in²

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

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

                         x = −2, 3

The values of x are −2 and 3.

f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).

Replace f(x) and g(x) with their given values:

h(x) = -2x + 4x -8

Combine like terms:

h(x) = 2x -8

Answer:

y = 1/4x + 17/4

Step-by-step explanation:

first lets umm find the slope

use points that you can um clearly see ?

(4, 6) and (8, 7)

so use the equation y2 - y1/ x2 - x1

soooo

7 - 6/ 8 - 4

1 / 4

so it looks like:

y = 1/4x + b

so far

now we have to find the y-intercept with a point we did not use yet

but i have a little trouble so ill try my best to estimate a point

(2, 5)

we substitue

5 = 1/4(3) + b

5 = 3/4 + b

b = 5 - 3/4

b = 17/4

i want to check but its hard looking for exact points. i think this is the answer hope this helps!

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.

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.

The [tex]x^{th}[/tex] number in the sequence will be   [tex]F[x]=\dfrac{5}{2} F[x][/tex]

The given function is

[tex]F[x]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1}[/tex]

Now at  [tex]x=x+1[/tex] for the function

[tex]F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x+1-1}[/tex]

[tex]F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x }[/tex]

Now we can write

[tex]F[x+1]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1} \dfrac{5}{2}^1[/tex]

Since     [tex]F[x]=\dfrac{3}{2} \times \dfrac{5}{2}^{x-1}[/tex]

so

[tex]F[x]=\dfrac{5}{2} F[x][/tex]

Thus the [tex]x^{th}[/tex] number in the sequence will be   [tex]F[x]=\dfrac{5}{2} F[x][/tex]

Considering the perimeter of the rectangular table, it is found that 36 ballons are needed.

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

P = 2(l + w).

In this problem, the dimensions of the table are l = 8 ft and w = 4 ft, hence the perimeter is of:

P = 2(l + w) = 2 x 12 = 24 ft.

Ballons will be attached 8 inches = 2/3 feet along the perimeter, hence the number of ballons needed is given by:

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

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.
