To get this answer you need to keep counting 24 seconds until it gets to exactly a minute, no seconds over or under, so 24x5=120 which is 2 minutes so it will be 2 minute. In other words to solve this you need to find a common factor 1 minute equals 60sec so 60x2=120 which is 2 min. So in 2 minutes the gears will be aligned again.

given
small=r=3 and h=5
V=(1/3)5pi3^2
V=5pi3
V=15pi

large, r=5, h=12
V=(1/3)5pi12^2
V=5pi48
V=240pi

F(x)=2x^3+ax^2-37x-60<br><br> The binomial x-4 is a factor of f(x). Find the value of a.
jekas [21]

Given:

The function is

f(x)=2x^3+ax^2-37x-60

The binomial x-4 is a factor of f(x).

To find:

The value of a.

Solution:

If x-c is a factor of f(x), then f(c)=0.

It is given that, x-4 is a factor of f(x), then f(4)=0.

We have,

f(x)=2x^3+ax^2-37x-60

Substituting x=4, we get

f(4)=2(4)^3+a(4)^2-37(4)-60

f(4)=2(64)+a(16)-148-60

f(4)=128+16a-208

f(4)=16a-80

Now,

f(4)=0

16a-80=0

16a=80

a=\dfrac{80}{16}

a=5

Therefore, the value of a is 5.
