Multiply the polynomials: (x + 3)(x2 – 5x + 12)
LekaFEV [45]

Answer:

x³ - 2x² - 3x + 36

Step-by-step explanation:

(x + 3)(x² - 5x + 12)

Each term in the second factor is multiplied by each term in the first factor , that is

x(x² - 5x + 12) + 3(x² - 5x + 12) ← distribute parenthesis

= x³ - 5x² + 12x + 3x² - 15x + 36 ← collect like terms

= x³ - 2x² - 3x + 36

Cylinders A and B are similar solids. The base of cylinder A has a circumference of 4pi units. The base of cylinder B has an
Wittaler [7]

Answer:

d) 9/4

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given circumference of cylinder A = π r² = 4π units

Given circumference of cylinder B = π r² = 9π units

The  dimensions of cylinder A are multiplied by \frac{9}{4}

   circumference of cylinder A = π r² = 4π(\frac{9}{4}) units     = 9 π units  

circumference cylinder A= 4π(\frac{9}{4}) units = 9 π units = circumference of cylinder B

<u><em>Final answer</em></u>:-

<em>The dimensions of cylinder A are multiplied by 9/4  produce the corresponding dimensions of cylinder B</em>

What degree slope is a 16' ramp with a 35" rise
masha68 [24]

Answer:

10.5 Degree.

Step-by-step explanation:

The inclined length of the ramp is 16' i.e. 16 feet i.e. (16 × 12) = 192 inches.

And the rise of the ramp is 35" i.e. 35 inches.

We have to calculate the degree of slope from the above information.

If we consider the ramp as the hypotenuse of a right triangle, then the perpendicular height is 35 inches.

Then angle of slope is given by  

\sin \theta = \frac{Perpendicular}{Hypotenuse} = \frac{35}{192} = 0.182

⇒ \theta =\sin^{-1} (0.182)=10.5 degree. (Answer)
