Step-by-step explanation:
Answer:
It’s incomplete
Step-by-step explanation:
The volume of a cylinder can be calculated by the product of the area of the base times the height of the shape. It is expressed as follows:
V = πr²h
We calculate as follows:
320π in³= π (r²) (5 in)
64 in² = r²
r = 8 in
Hope this answers the question. Have a nice day.
Answer: 2 distinct complex solutions (ie non real solutions).
Work Shown:
The given equation is in the form ax^2+bx+c = 0, so
a = 1, b = 3, c = 8
Plug those into the formula below to find the discriminant
D = b^2 - 4ac
D = 3^2 - 4(1)(8)
D = -23
The discriminant is negative, so we get two nonreal solutions. The two solutions are complex numbers in the form a+bi, where a & b are real numbers and
. The two solutions are different from one another.
