What are the leading coefficient and degree of the polynomial? 20-w^9+2w^3+12w

Ilya [14]

I assume you want the leading coefficient because there is only 1.

The leading coefficient is always in front of the term with the greatest exponent.

Leading coefficient = -1.

The degree of this function is 9. It is a ninth degree polynomial function. Why 9? It is a 9th degree polynomial because 9 is the greatest power.

Seven times the difference of x and 4 is -10

4vir4ik [10]

Answer:

In this equation x = 2

Step-by-step explanation:

First, it is easiest to convert these words to numbers. That would make it

4 - x · 7 = -10

First subtract 4 from both sides.

4 - x · 7 - 4 = - 10 - 4

Then you simplify.

-x · 7 = -14

Divide both sides by 7.

$\frac{-x(7)}{-7} = \frac{-14}{-7}$

Then you simplify that fraction to 2 and thats how you get your answer.

HELP 30 POINTS!!!!!

Tamiku [17]

by pythagorean formula, the last side is √(61)

by cos rule

cos A

$= \frac{ {6}^{2} + 61 - {5}^{2} }{2 \times 6 \times \sqrt{61} } \\ = \frac{72}{12 \sqrt{61} } \\ = \frac{6}{ \sqrt{61} }$

A = 39.81
