Hi there!

f(x) = x^3 - 8x^2 + 16x

The multiplicity of a root is the number of times the root appears.

So the answers are

x = 0 and the multiplicity of 1
x = 4 and the multiplicity of 2

I hope this helps!

Good luck!

Find the volume of a cone with a height of 12 yd and a base diameter of 10 yd.
anyanavicka [17]

Answer:

The volume of the cone is 314yd³

Step-by-step explanation:

radius = half of diameter

d = 10yd

r = 10yd / 2 = 5yd

First of all to solve this problem we have to know the formula to calculate the volume of a cone

v = volume

r = radius  = 5yd

h = height  = 12yd

π = 3.14

v = 1/3 * π * r² * h

we replace with the known values

v = 1/3 * 3.14 * (5yd)² * 12yd

v = 1/3 * 3.14 * 25yd² * 12yd

v = 314yd³

The volume of the cone is 314yd³

Two angles of a triangle have equal measures, but the third angle's measure is 82° . Find the measure of each angle of the trian
Nonamiya [84]

Answer:

Step-by-step explanation:

Two angles each  =x because both are equal.

All triangles have angles adding to 180 degrees

The angle that isn't = x is 82 degrees.

x + x + 82 = 180              Subtract 82 from both sides

2x + 82 - 82 = 180 - 82  Combine

2x = 98                            Divide by 2

2x/2 = 98/2

x = 49

angle 1 = 49

angle 2 = 49

angle 3 = 82
