Find the midpoint of the segment with the following endpoints. (3, 2) and (9, 6)
myrzilka [38]

Answer:

The answer is

<h2>( 6 , 4 )</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 the points are

(3, 2) and (9, 6)

The midpoint is

M = ( \frac{3 + 9}{2}  \:  , \:  \frac{2 + 6}{2} ) \\  = ( \frac{12}{2}  \: , \:  \frac{8}{2} )

We have the final answer as

<h3>( 6 , 4 )</h3>

Hope this helps you

A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm,
Svetradugi [14.3K]

Answer:

The quadratic equation that best models the volume of the box (in terms of W) is:

70W-5W^2

Step-by-step explanation:

The perimeter of the rectangular base = 28cm

Perimeter of a rectangle = 2(L+W)

2(L+W)=28

L+W=14

L=14-W

Volume of the Box= LWH

Since L=14-W and Height Of the Box= 5cm

Volume of the Box= (14-W)W X 5

=5(14W-W^2)\\                             =70W-5W^2
