Write the equation of the line perpendicular to 2x-3y=12 which passes through the point (16,-7).

Elanso [62]

Y= mx+b

(16, -7) = (x,y)

2(16) - 3y = 12
32 - 3y = 12
32 - 12 = 3y
20/3 = y
6.6 = y

2x-3(-7) = 12
2x+21 = 12
2x = 12 - 21
x = -9/2

Insert the values into y = mx + b
solve for m and then solve for b

Find the diagonal of the rectangular prism to the nearest tenth.<br> 4 in<br> 3 in<br> 10 in

hoa [83]

Given:

Consider the dimensions of a rectangular prism are 4 in by 3 in by 10 in.

To find:

The length of the diagonal.

Solution:

Length of diagonal of a rectangular prism is:

$d=\sqrt{l^2+b^2+h^2}$

Where l is length, b is breadth and h is height.

The dimensions of a rectangular prism are 4 in by 3 in by 10 in. So, the length of diagonal of the rectangular prism is:

$d=\sqrt{(4)^2+(3)^2+(10)^2}$

$d=\sqrt{16+9+100}$

$d=\sqrt{125}$

$d=5\sqrt{5}$

Approximate the value to the nearest tenth.

$d\approx 11.2$

Therefore, the length of diagonal of the rectangular prism is 11.2 in.
