Answer:
V= 64 ft^3
Step-by-step explanation:
The volume of a pyramide is given by the formula
V = 1/3 l*w*h
Given the l = 8 w = 4 and h = 6
V = 1/3 ( 8*4*6)
V = 1/3 ( 192)
V= 64 ft^3
Answer:
123.94
Step-by-step explanation:
We will use the substitution:
t = x² ;
t² + 21 x - 100 = 0
t² + 25 t - 4 t - 100 = 0
t ( t + 25 ) - 4 ( t + 25 ) = 0
( t + 25 ) ( t - 4 ) = 0
t 1 = - 25, t 2 = 4
x = √t
Answer:
The roots are:
x 1 = 5 i
x 2 = - 5 i
x 3 = - 2
x 4 = 2
Answer:
