The answer is D 6.32
S= the slant Height
Then we need to get the apothem of the lower and upper base
S^2 = (apothem of the lower base - apothem of the upper base)^2 + (height)^2 
and they would be like this:
apothem of the lower base = 8 / 2*tan(90/2) = 4 
apothem of the upper base = 4 / 2*tan(90/2) = 2 
S^2 = (4 - 2)^2 + (6)^2 
S^2 = 2^2 + 6^2 
S^2 = 4 + 36 
S^2 = 40 
<span>S = 6.32 </span>

PLS HELP ASAP calculate the distance between the two points. (18, -24) &amp; (87, 100)
GarryVolchara [31]

Answer:

<h3>The answer is 141.90 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

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

From the question the points are

(18, -24) & (87, 100)

The distance between them is

d =  \sqrt{ ({18 - 87})^{2} +  ({ - 24 - 100})^{2}  }  \\  =  \sqrt{ ( { - 69})^{2}  + ( { - 124})^{2} }  \\  =  \sqrt{4761 + 15376}  \\  = \sqrt{20137}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  = 141.90489773...

We have the final answer as

<h3>141.90 units</h3>

Hope this helps you

14,000 acres of a 40,000 acre forest burned in a forest fire. what percentage of the forest was damaged?
Oksanka [162]
% damaged =   (14 000/40000) * 100%
 
                    =  14/40 * 100%
                    
                    = 0.35*100%
 
                    = 35%

What is the equation of the line that passes through the point (-6, -7) and has a slope of 0 <br>​
Natali [406]

Answer:

x = - 6

Step-by-step explanation:

A line with a slope of zero is a horizontal line parallel to the x- axis with equation

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, - 7 ) with x- coordinate - 6 , then

x = - 6 ← equation of line

Solve : cos X + sin X = 0 <br> Pls all answers in radians<br> thanks
Alisiya [41]
<span>cos (X) + sin (X) = 0

Subtract cos(x) from each side:

sin(x) = -cos(x)

Divide each side by cos(x) :

sin(x) / cos(x) = -1

But sin/cos = tangent

<em>tan(x) = -1</em>

x = 135° and 315°

x = 3/4 pi radians  and  7/4 pi radians
