Answer:
9 ft
Step-by-step explanation:
Let's begin with the formula for the volume of a square pyramid. If s is the base length, then the area of the base is s^2. The volume of the pyramid is then V = (1/3)(base area)(height). We know the volume and the base length (s), and want to find the height. Solving V = (1/3)(base area)(height)
for height, we get:
3V = (base area)(height), or
3V
---------------- = height
base area
Substituting 75 ft^3 for V and (5 ft)^2 for base area, we get:
3(75 ft^3) 9 ft
height = ------------------ = ----------------- = 9 ft
25 ft^2 1
The fraction in its simplest form is 27/100 .
Standard form is ax+by=c wher a and b and c ar integers
another
y-y1=m(x-x1)
that is the equation of a line that has a slope of m and passes through (x1,y1)
find slope
slope between the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-3,5) and (-2,-6)
slope=(-6-5)/(-2-(-3))=(-11)/(-2+3)=-11/1=-11
a point is (-2,-6)
y+6=-11(x+2)
distribute
y+6=-11x-22
add 11x both sides
11x+y+6=-22
minus 6 both sides
11x+y=-28
