Answer:
5 roots (answer C)
Step-by-step explanation:
Any polynomial should have in the Complex Number System, as many roots as the polynomial's degree.
In our case, since we are dealing with a polynomial of order 5 (degree 5), it should have 5 roots in the Complex Number System.

Given:
A prism has a base area of
square units and a volume of
cubic units.
To find:
The volume of the cylinder if the cylinder has the same base area and height.
Solution:
Volume of a prism is:

Where, B is the base area and h is the height of the prism.
The volume of cylinder is:


Where, r is the radius, h is the height of the cylinder and
is the base area.
Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.
Hence the volume of the cylinder is
cubic units.
Answer:
5 minutes
Step-by-step explanation:
We know that 1760 yards are in a mile. We can convert the given info into a proportion. 440/75 = 1760/x, where x is the number of seconds it takes to run a mile. Cross-multiply to get 440x = 75*1760. Divide both sides by 440 to get x = 75*4 = 300 seconds. The problem asks for how many minutes so you have to convert 300 seconds to minutes. To do this, we have to divide 300 by 60 to get 5 minutes.
Answer:

Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(8x - 13)
= 
=
