HELP ASAP! GIVING BRAINLIEST!!

Mumz [18]

Answer:

AB is A

BC is B

AC is D

Step-by-step explanation:

To find the length of each side, use the formula for the distance between coordinate pairs.

We can find the distance using the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

AB

We then substitute (-3,6) as $(x_1,y_1)$ and (2,1) as $(x_2,y_2)$ .

$d=\sqrt{(2--3)^2+(1-6)^2} \\d=\sqrt{(2+3)^2+(-5)^2} \\d=\sqrt{25+25}\\d=\sqrt{50}$

BC

We then substitute (2,1) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9-2)^2+(5-1)^2} \\d=\sqrt{(-7)^2+(4)^2} \\d=\sqrt{49+16}\\d=\sqrt{65}$

AC

We then substitute (-3,6) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9--3)^2+(5-6)^2} \\d=\sqrt{(12)^2+(-1)^2} \\d=\sqrt{144+1}\\d=\sqrt{145}$

You want to find the area of the front of a house, whose shape is a triangle on top of a rectangle with a width of 12. The trian

AlladinOne [14]

There are two shapes

rectangle and triangle

Rectangle area = Length × breadth

Triangle area = ( 1 / 2 ) × height × base

L = 12

W = 5

Area = 60

Height = 14

base = width of rectangle

base = 12

( 1 / 2 ) ( 12 ) ( 14 )

( 14 ) ( 6 )

Total area = 60 + 84

= 144

Hope helps!

Determine, to one decimal place, the length, width & height of the rectangular prism that would have the greatest volume, wi

Leya [2.2K]

Answer:

The length = The width = The height ≈ 5.8 cm

Step-by-step explanation:

The volume of a rectangular pyramid, V = l × w × h

The surface area of the pyramid = 2 × l × h + 2 × w × h + 2 × l × w = 200

∴ l × h + w × h + l × w = 200/2 = 100

We have that the maximum volume is given when the length, width, and height are equal and one length is not a fraction of the other. Therefore, we get;

At maximum volume, l = w = h

∴ l × h + w × h + l × w = 3·l² = 100

l² = 100/3

l = 10/√3

Therefore, the volume, v = l³ = (10/√3)³

The length = The width = The height = 10/√3 cm ≈ 5.8 cm
