Waistline 100cm is the circle circumference->calculate radius
100cm=1m=2*r*π
0.5=r*π
0.5/π=r
area of a circle: A=r²π=(0.5/π)²π=0.25/π m²
circlearea*height=cylinder volume
1.8*0.25/π=0.45/π m³~0.143239 m³
so the second option is the correct one
Answer:
A
Step-by-step explanation:
We are given two functions:
And we want to find:
Thus:
We can factor the denominator of the first term:
In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:
Multiply:
Combine:
Simplify:
We can expand the denominator:
Therefore, our answer is A.
Answer:
t₁ = 2,75 sec
Step-by-step explanation:
The ball will get h maximum when dh/dt ( its vertical component of the speed is equal to 0. At this moment the ball has flown half of the total flight time
Then
h(t) = - 4t * ( 4*t - 11 )
h(t) = - 16*t² + 44*t
Taking derivatives on both sides of the equation we get:
dh/dt = - 32*t + 44
dh/dt = 0 ⇒ -32*t + 44 = 0
t = 44/32 ⇒ t = 1,375 s
So twice this time
2*t = 2 * 1.375
Total time t₁ = 2,75 sec
The height of the cone would be 10 being that fact that if multiplied by 2 you get 20x 5 equals 100
