Answer:

P(x) =x³-4x²-31x+70

Step-by-step explanation:

The function is expressed as:

P(x) = (x+5)(x-2)(x-7)

P(x) =(x²-2x+5x-10)(x-7)

P(x) = (x²+3x-10)(x-7)

P(x) = x³-7x²+3x²-21x-10x+70

P(x) =x³-4x²-31x+70

Hence the polynomial is P(x) =x³-4x²-31x+70

<span>A new kind of temporary pavilion support for a square roof uses just two poles set at the diagonal corners of a square. The allowable distance between the poles is 18 feet. Find the area of the roof. The sides will have lengths of 18/sqrt(2). Since they are perpendicular, the area of the square will be (18^2)/2 = 81*4/2 = 162 square feet.

A right circular cylinder has a height of 19 3/4 ft and a diameter 1 2/5 times its height. What is the volume of the cyl

SVETLANKA909090 [29]

Answer:

$V=16,594.15 ft^{3}$

Step-by-step explanation:

The volume of a cylinder is defined as

$V= \pi r^{2} h$

So, by given we know that the diameter of the circular base is $1 \frac{2}{5}$ times its height which is $19 \frac{3}{4}ft$ , if we transform each mixed number into a fraction, it would ne
