Answer:
Step-by-step explanation:
Answer: r = 4
Step-by-step explanation:
V = pi * r^2 * h
144 * pi = pi * r^2 * 9
Divide by pi
144 = r^2 * 9
Divide by 9
16 = r^2
Take square root of both sides
rad(16) = rad(r^2)
4 = r
r = 4
It`s easy.
Real axis (-4) is the abscissa, the part with i (-8) is the ordinate. That`s why...
Two points are just two points. They have no slope/intercept form. But the line that joins them has.
Answer: z = 0 | Equation is not solvable
Step-by-step explanation:
We have 3 = 7 - 2(3z + 2)
When we distribute the 2, we get: -6z - 4 + 7 = 3
Combine like terms: -6z + 3 = 3
Subtract the left hand side 3 from the right hand side 3: -6z = 0
We can not divide by zero thus the equation is not solvable.
