<h2 /><h2> Answer:</h2>

\large\color{green}{ \tt{2w³ +3w² −w}}

<h3>Step by Step Solution: </h3>

  • <u>Use the distributive property to multiply – w by – 2x – 3w + 1</u><u>.</u>

\large\color{green}{ \tt{−2(−w)w² −3(−w)w−}}

  • <u>Multiply −2 and −1 to get 2.</u>

\large\color{green}{ \tt{2ww² − 3(− w)w − w}}

  • <u>To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.</u>

\large\color{green}{ \tt{2w³ − 3(−w)w − w}}

  • <u>Multiply −3 and −1 to get 3.</u>

\large\color{green}{ \tt{2w³ + 3ww − w}}

  • <u>Multiply w and w to get w².</u>

\large\color{green}{ \tt{2w³ + 3w² - w}}

Hope It's Help

Find the length of the hypotenuse of a right triangle with legs of 8 and 6.
makvit [3.9K]
Answer: 10
Explanation:
formula for hypotenuse : a^2+b^2=c^2
8^2+6^2=c^2
64+36=c^2
100=c^2
so we find the square root of 100 and its is:
c=10

What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)?
salantis [7]

Answer:

tg (-60°) = -√3

Step-by-step explanation:

We can solve this, using a calculator, but I would like you to understand this problem without the use of that.

This is trigonometry, so first we need to know the value of pi in trigonometry.

The value of π is equals to 3.14 but in this case, we need to take the value of π in degrees. This value is 180°.

Now, the following step is replace this value into the expression:

tg (-180/3) = tg (-60°)

So the actual value we are looking for is tangent of 60°. Tangent can be calculated using the expression with the sin and cosine so:

tg = sin/cos

so to get the value of tg 60°:

tg 60° = sin 60° / cos 60°

The value of sin 60° = √3/2, while the value of cos 60° = 1/2, so replacing both values above, we can get the value of tg 60°:

tg 60° = (√3/2) / (1/2)   both 2 gets cancel out so:

tg 60° = √3 / 1

tg 60° = √3

As we want tg(-60) the real value would be:

tg (-60°) = -√3

So the answer would be option 1.

1) Is this graph a linear function? Explain.....2) Is this graph a linear function? Explain....
Sav [38]

9514 1404 393

Answer:

  1. no
  2. no

Step-by-step explanation:

If the graph is not a straight line, it is not a linear function. Neither graph 1 nor graph 2 is a straight line, so neither is a linear function.

__

Graph 2 is made of parts of two straight lines. It is not one straight line, so not a linear function. It is called "piecewise linear," which is different.

-5f-2+8-3k use f=7 and k=8
gulaghasi [49]
The answer to this equation is -53. This is because 7 times -5 equals -35. -35-2 equals -37. -3 times 8 equals -24. -24 plus 8 equals -16. -37+(-16)= -53

A newborn kitten weighs 3 ounces at birth. After four weeks, it weighs 13 ounces. Which of the following is true?
Dafna11 [192]

Answer:

Step-by-step explanation:

By this age you can give your kitten 1/3 to 1 cup of kitten food per feeding three times a day. If giving wet food, you can give 2/3 of a 3-ounce can for every pound of body weight on a daily basis. Give ½ of a 3-ounce can of kitten food for every pound of body weight per day.
