Answer:

-1/4

Step-by-step explanation:

Take two points on the line

(-4,-1) and (0,-2)

Using the slope formula

m = (y2-y1)/(x2-x1)

   = ( -2 - -1)/( 0 - -4)

    = (-2+1)/ ( 0+4)

    -1/4

The cylinders are similar. The volume of the larger cylinder is 9648 cubic inches. What is the volume of the smaller cylinder?
zalisa [80]
Hey there :)

The volume formula of a cylinder is:
V = \pir²h

The volume of the larger volume is given to be 9648³ and the height is 18 in
We need to find the radius first

9648 = \pir²(18)
\frac{9648}{18} = \pir²
536 = \pir²
\frac{536}{ \pi} = r²
\sqrt{ \frac{536}{ \pi } } = r
r ≈ 13.06

The ratio of the big cylinder to small cylinder is:
18 : 9   (given height)
So the big cylinder is 2 times bigger than the small cylinder
Therefore the radius of the big cylinder is as well 2 times bigger

\frac{13.06}{2} = r
r ≈ 6.53  ( the radius of the small radius )

V (of small cylinder) = \pi(6.53)²(9)
                                  = 1206 in³

What is the midpoint of equation if N(10, −14) and P(−16, −4)?
meriva

Answer:

The answer is

<h2>( - 3 , - 9)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x_1 + x_2}{2} , \:  \frac{y_1 + y_2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question

N(10, −14) and P(−16, −4)

The midpoint is

M = ( \frac{10 - 16}{2}   \: , \:  \frac{ - 14 - 4}{2} ) \\  = (  - \frac{6}{2}  \: , \:  -  \frac{18}{2} )

We have the final answer as

<h3>( - 3 , - 9)</h3>

Hope this helps you

Firlakuza [10]
David Howell was shopping for a leather jacket and found one on the dept. store that costs 395 dollars.
Now, he learned that an inflation rate of 4.5% has occurred since the jacket was originally priced.
=> 395 dollars * .045 = 17.775
=> 395 dollars - 17.775  = 377.23 is the original price of the jacket.
