Add 5 to both sides. Then 45/v is greater than or equal to -8.

Mult. both sides by v to obtain "45 is greater than or equal to -8v."

Solving for v: v is smaller than or equal to -45/8, or smaller than or equal to -5 5/8. Does -3 satisfy this criterion? NO. Eliminate -3.
Does -9 satisfy this criterion? YES. And so on.

Answer:

60 degrees

Step-by-step explanation:

First find angle I by using the sum of the angles in a triangle is 180 degrees

59+61+I = 180

120 + I = 180

I = 180-120

I =60

<I = <x since they are corresponding angles

<x = 60 degrees

Given the polynomial 2x3 + 18x2 − 18x − 162, what is the value of the coefficient 'k' in the factored form?2x3 + 18x2 − 18x − 16

s344n2d4d5 [400]

Answer:

$k=3$

Step-by-step explanation:

Let

$f(x)=2x^3+18x^2-18x-162$

We factor 2 to obtain;

$f(x)=2(x^3+9x^2-9x-81)$

We factor the polynomial within the parenthesis by grouping.

$f(x)=2(x^2(x+9)-9(x+9)$

$f(x)=2(x^2-9)(x+9)$

$f(x)=2(x^2-3^2)(x+9)$

We apply difference of two squares on the second factor: $x^2-3^2=(x-3)(x+3)$

$f(x)=2(x+3)(x-3)(x+9)$

We now compare to;

$f(x)=2(x+k)(x-k)(x+9)$

It is now obvious that $k=3$

Tanya [424]

Series = {2, 5 ,6, 7, 15, 16, 17}

Here, Median = 7

Then Q3 = {15, 16, 17}
Median of Q3 = 16

In short, Your Answer would be: 16
