The pyramid shown has a square base that is 18 inches on each side. It has a surface area of 864 square inches. What is the slan
disa [49]
The first step is to find the relationship between the square base and the surface area.

Surface area (SA) = area of the square (SS) + area of triangles.4(AT) 

Thus we can conclude area of triangles 4(AT) = SA - SS = 864 - (18*18)

4(AT) = 864 - 324 = 540

Each triangle = 540/4 = 135 square in.

An area of one triangle (AT)= (base* slant height)/2

The base = 18 in.

<span>slant height = 2(AT)/base = 2(135)/18 = 15</span>

Answer:

(24,4,84)

Step-by-step explanation:

Since they restricted our domains to certain x values, we can find the range by plugging in the x values to find it y value or output.

f( - 2) = 5( { - 2}^{2} ) + 4

5(4) + 4 = 24

f(0) =  - 5( {0}^{2} ) + 4 = 4

5(4) {}^{2}  + 4 = 84

So our range is (24,4,84)
