Answer:

8x^3+28x^2-16x

Step-by-step explanation:

Volume of rectangular prism: l*b*h (l = length, b = breadth, h = height.)

Volume of rectangular prism:

(x+4)*(2x-1)*4x

4x\left(x+4\right)\left(2x-1\right)

Expand the two brackets using FOIL:

4x(x* \:2x+x\left(-1\right)+4* \:2x+4\left(-1\right))

4x\left(2x^2+7x-4\right)

Expand:

4x* \:2x^2+4x* \:7x+4x\left(-4\right)

8x^3+28x^2-16x

HURRICANES A category 3 hurricane reaches speeds up to 20.88 kilometers per hour. The distance from Cuba to Key West is 145 kilo
White raven [17]
Let us assume that the time taken by the category 3 hurricane to travel from Cuba to Key West = X minutes
Speed of the category 3 hurricane is given as 20.88 km/hr
So the category 3 hurricane can travel 20.88 km in 1 hour.
The distance between Cuba and Key West = 145 km
Then
20.88 km is travelled by the category 3 hurricane in = 60 minutes
145 km from Cuba to Key west is travelled by the category 3 hurricane in = X minutes
So,
X = [(145 * 60)/20.88] minutes
   = 416.66 minutes
   = 17 hours and 36 minutes
Time taken by the category 3 hurricane to reach Key West from Cuba is 17 hours and 36 minutes.

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

In general (x, y, z) = (p ·cos s ·sin t, p· sin s· sin t, p · cos t) where p is radius

x(s, t)= 3 ·cos s ·sin t

y(s, t)= 3· sin s· sin t

z(s, t) = 3· cos t

Where, radius is 3, s ∈ [0,2π), and t ∈ [0, π]
