Answer:

4.5 cm.

Step-by-step explanation:

The volume of the pyramid = 1/3 * area of the base * height.

Area of the triangle = 1/2 * base * height

= 1/2 *  14 * 8

= 56 cm^2.

So  the volume of the pyramid =

84 =  1/3 * 56 * h

h = 84 / (1/3 * 56)

h = 84 * 3 / 56

= 4.5 cm.

Write the equation of a line that is perpendicular to the given line and that passes through the given point.
Igoryamba

Answer:

y = -1\frac{1}{2}x - 4

Step-by-step explanation:

5 = −1½[−6] + b

9

-4 = b \\ \\ y = -1\frac{1}{2}x - 4

Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so ⅔ becomes −3⁄2 [or −1½].
