The formula is:
V = π(r^2)h/3
Since this problem gives you the diameter and not the radius, I would take half of the diameter because a radius is half of a diameter. 
The half of 8 is 4, so the radius is 4
V = π(4^2)(9/3)
V = π(4^2)(3)
V = π(16)(3)
V is about 150.8

At what points on the graph of f(x)=2x^3-6x^2-27x is the slope of the tangent line -9?
Dmitriy789 [7]

Answer:

(-1, 19) and (3, -81)

Step-by-step explanation:

f(x) = 2x³ − 6x² − 27x

f'(x) = 6x² − 12x − 27

-9 = 6x² − 12x − 27

0 = 6x² − 12x − 18

0 = x² − 2x − 3

0 = (x + 1) (x − 3)

x = -1 or 3

f(-1) = 19

f(3) = -81

The points are (-1, 19) and (3, -81).

Camryn practices the trumpet every 11th day and the flute every 3rd day. Camryn practiced both the trumpet and the flute today.
QveST [7]

Answer: 33 days.


Step-by-step explanation:

Given :- Camryn practices the trumpet every 11th day and the flute every 3rd day.

Camryn practiced both the trumpet and the flute today.  

To find the number of days until Camryn practices the trumpet and flute again in the same day, we need to find the least common multiple (L.C.M.) of 11 and 3.

As they both are co-prime numbers thus its L.C.M.= 11×3=33

Therefore, Camryn practices the trumpet and flute again in the same day after 33 days.

A.) Find the product (-1.15) x 3.2 b.) Explain in words HOW you determined the sign of your answer.
Deffense [45]

(A)

we are given

(-1.15) x 3.2

Since, sign of 1.15 is negative

and sign of 3.2 is positive

so, we put negative sign in front

(-1.15)*(3.2)=-(1.15*3.2)

now, we can multiply them

and we get

(-1.15)*(3.2)=-3.68.............Answer

(B)

Suppose, we are given product of two numbers 'a' and 'b'

so, we use this property

case-1: When both positive , then we put positive in front

a*b=+(a*b)

case-2: When both negative  , then we put positive in front

-a*-b=+(a*b)

case-3: When first is  negative and second is positive   , then we put negative  in front

-a*b=-(a*b)


case-4: When first is  positive and second is negative    , then we put negative  in front

a*-b=-(a*b)
