The correct Option is (D) <span>y = -0.15x + 1.95

Explanation:
The linear (line) equation is:
y = mx + c

Where
m = slope = rise/run = -0.3/2 = -0.15 (negative sign indicates the downward slope)
c = y-intercept = 1.95 (in graph)

Plug in the values in line equation:
y = -0.15x + 1.95 (Option D)</span>

What is the volume of a square pyramid with base edges 24 feet and slant height 37
-Dominant- [34]

Answer: The volume of pyramid is 6720 ft³

Step-by-step explanation:

Given: Base edge of a square pyramid = 24 feet

Slant height = 37 feet

Therefore height of pyramid is given by

h^2=l^2-\dfrac{1}{2} b^2 where h is height, l is slant height and b is base edge of pyramid

So we have

h^2= 37^2-(\dfrac{1}{2} \times 24)^2= 37^2-12^2=1225 \\\\\Rightarrow h= \sqrt{1225} =35

Height of pyramid is 35 feet

Now the volume of a pyramid is given by

V=b^2\dfrac{h}{3} where V is volume , b is base edge and h is height of pyramid

Therefore

V= (24)^2\dfrac{35}{3} = 6720

Hence , the volume of pyramid is 6720 ft³
