If (x+2) is a factor of x^3-6x^2+kx+10, k=
tensa zangetsu [6.8K]
If a polynomial is divisible by x-a, then a is a root of this polynomial.
Here (x-a) is equal to x+2:

x-a=x+2 \\
-a=2 \\
a=-2

So -2 is a root of the polynomial. That means <span>x³-6x²+kx+10</span>=0 for x=-2. Now substitute -2 for x in the equation and solve for k:

(-2)^3-6 \times (-2)^2+ k \times (-2)+10=0 \\&#10;-8-6 \times 4-2k+10=0 \\&#10;-8-24-2k+10=0 \\&#10;-2k-22=0 \\&#10;-2k=22 \\&#10;\boxed{k=-11}

Factor completely 2x5 + 10x4 − 22x3.
Luba_88 [7]

Given equation is :

2x^{5}+10x^{4}-22x^{3}=0

Taking out 2x^{3} common we get,

x^{2}+5x-11=0

Now solving this we get,

As 11 is not factor-able, we will solve it using the formula,

x=\frac{-b+\sqrt{b^{2}-4ac}}{2a}

a=1 b=5 and c=-11

we get,

x=\frac{-5+\sqrt{69} }{2} and x=\frac{-5-\sqrt{69} }{2}

A plane descends to sea level from 36 comma 400 feet after being airborne for 1 and one half hours. The entire flight time is 3
andrew-mc [135]

Answer:

350 feet per minute

Step-by-step explanation:

The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.

This means it took 104 minutes for the plane to descend 36,400 feet.

Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.
