Answer:

This is just the application of Pythagoras theorem

To find how high up the wall the ladder reach

⇒ 13^2 = x^2 + 5^2

therefore x^2 = 13^2 - 5^2

x^2 = 169 -25

x^2 = 144

x = 12

therefore the ladder is 12 foot high up the wall

Answer:

$m=0$

Step-by-step explanation:

Given

See attachment

Required

Determine the slope of the line

From the attachment, we have the following points

$(x_1,y_1) = (-4,1)$

and

$(x_2,y_2) = (3,1)$

The slope m is then calculated using:

$m = \frac{y_2- y_1}{x_2 - x_1}$

Substitute values for the x's and y's

$m = \frac{1-1}{3 - (-4)}$

$m = \frac{1-1}{3 +4}$

$m = \frac{0}{7}$

$m=0$

<em>Hence, the slope is 0</em>

What is the area of the base of a triangular prism if the volume is 210 ft3 and the height is 14 ft?

Oksi-84 [34.3K]

We have the area of the base of a triangular prism= a*b
the volume of triangular prism =a*b*c( where c is the height) so that 210=a*b*14 ==> 210= base area*14==> base area= 210/14
