SA = ?
<span>r = 2x - 1 </span>
<span>h = 3x </span>

<span>Then, </span>

<span>SA = 2π(2x - 1)² + 2π(2x - 1)(3x) </span>
<span>==> 2π(4x² - 4x + 1) + 6πx(2x - 1) </span>
<span>==> 8πx² - 8πx + 2π + 12πx² - 6πx </span>
<span>==> 20πx² - 14πx + 2π units² </span>

X2 + y2 - 14x + 10y + 65 = 0 <br><br> will lie ENTIRELY in Quadrant

Afina-wow [57]

Rearranging to standard form
= (x - 7)^2 + (y + 5)^2 = -65 + 49 + 25
(x-7)^2 + (y+5)^2 = 9
so the centre is at (7,-5) and the radius is 3

so the circle will be entirely in Quadrant 4.

John had 80 filers to post around town. Last week, he posted 1/4 of them. This week, he posted 3/5 of the remaining filers. How

Reil [10]

Answer: 24 fliers

Step-by-step explanation:

he had 80 to begin with so last week if he posted 1/4 of them he would have 3/4 left and

3/4 * 80 = 60

and then if he posts 3/5 of the 60 remaining fliers he would have 2/5 left over and

2/5 * 60 = 24

so your answer is 24 fliers

Given the line below.

geniusboy [140]

Answer:

The equation of the line in point slope form is equal to

$y+2=(x+2)$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,-2) and (2,2)

substitute the values

$m=\frac{2+2}{2+2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(x1,y1)=(-2,-2)$

substitute the values in the formula

$y-(-2)=(1)(x-(-2))$

$y+2=(x+2)$
