Answer:Set \displaystyle f\left(x\right)=0f(x)=0.

Step-by-step explanation:

Set \displaystyle f\left(x\right)=0f(x)=0.

If the polynomial function is not given in factored form:

Factor out any common monomial factors.

Factor any factorable binomials or trinomials.

Set each factor equal to zero and solve to find the \displaystyle x\text{-}x- intercepts.

In a game if you roll 1 on a 6 sided number cube you lose a turn. Answer for a b and c and explain each answer show your work.
Drupady [299]
(A) The probability that you roll a 1 would be 1/6 because there are six sides of a dice and only one is a 1.

(B) The probability that you either roll a 1 or don't roll a 1 is 1/6 and 5/6, since the probability that you do roll a 1 is 1/6 and the probability that you don't is 5/6 since the other 5 sides of the dice are not ones.

(C) As stated above, the probability of not rolling a 1 is 5/6 since there are 6 sides of the dice and 5 are NOT ones.

Hope that helped!

Two cylinders are shown below. Find the volume of each cylinder. Use 3.14 for pie. Enter your answers rounded to the nearest hun
Alchen [17]

Given:

For cylinder P: radius = 4.25 in. and height = 14 in.

For cylinder Q: radius = 7 in. and height = 8.5 in.

To find:

The volume of each cylinder.

Solution:

Volume of a cylinder is

V=\pi r^2h

where, r is radius and h is height. Use 3.14 for \pi.

Using the above formula, the volume of cylinder P is

V_P=(3.14)(4.25)^2(14)

V_P=794.0275

V_P\approx 794.03

Using the above formula, the volume of cylinder Q is

V_Q=(3.14)(7)^2(8.5)

V_Q=1307.81

Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.
