Write One Polynomial For Each Description

Answers

Answer 1

Answer:

21. 4x^2 - 2 + 5x^3

22. 7a^2 + 9y - 4y^4 + 6

23. b^5 + 5

24. -9a + 3z - 7z^3 + 5

25. 3r^2

Step-by-step explanation:

I don't know if I did it correctly but based on what I understand I think this is how you do this exercise.

Example: 5x^2 - 2x + 1 < This is a Trinomial because it has three terms, but there is more to it.

In 5x^2 - 2x + 1, the highest exponent is 2 (^2 from 5x^2) < therefore this is a 2nd-degree Trinomial.

Another example: 3x^4 + 4x^2 < This is a Binomial (two terms) but there's more to it.

In 3x^4 + 4x^2, there are two different exponents 4 and 2, but we are focusing on the highest exponents which is 4 (^4 from 3x^4) < therefore this a 4th-degree Binomial.  

Hope this can help you in the future!

The following linear equation represents the line of best fit for the following scatter plot

y=0.15x-1.5

Use the equation to answer the following questions. Predict the amount of hits a player would have to do to have 35 home runs.

A) About 4 hits
B) 223 hits
C) About 243 hits
D) 175 hits

Answers

Answer:

C) About 243 hits

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 35

Step 2: Solve for x hits

Substitute [BLF]:                    35 = 0.15x - 1.5Add 1.5 on both sides:          36.5 = 0.15xDivide 0.15 on both sides:    243.333 = xRewrite:                                  x = 243.333

Remember that this is a prediction. According to the best line of fit, we would need approximately ~243 to get 35 home runs.

Answer:

D.) 38 cm²

Step-by-step explanation:

apologies if this isn't correct but I hope it is, anyway have a good day/night!

the area of the figure is 38.28cm².

The area of the shape is the sum of the area of the semicircle, a rectangle, and a right triangle.

Area of a semicircle = [tex]\frac{1}{2}[/tex]πr²

[tex]\frac{1}{2}[/tex]x 3.14 x (4/2)²  = 6.28 cm²

Area of the rectangle = length x width

6 x 4 = 24 cm²

Area of the right triangle =  [tex]\frac{1}{2}[/tex]x base x height

[tex]\frac{1}{2}[/tex]x (10 - 6) x 4 = 8cm²

Sum of the areas = 8 + 24 + 6.28 = 38.28cm²
