Simplify
(8x + 3)(2^2+ 8x +9)

Answers

Answer 1

Answer:

64x²+128x+39

Step-by-step explanation:

(8

Answer 2

Answer:

First distribute (8x + 3) into (2^2+ 8x +9)

16x^3 + 64x^2 + 72x + 6x^2 + 24x +27

Then we'll order the pairs from highest to lowest degree

16x^3 + 64x^2 + 6x^2 + 72x + 24x + 27

Then we'll add up the like terms

16x^3 + 70x^2 + 96x + 27

That should be your final answer simplified.

It is not a function because if you draw a straight line on the graph shown, it will pass more than one point. Basically the graph passes a line from more than one points it is not a function. If it passes only one point than it is a function.

In the year 1984 the average American used to eat 55.7 pounds of chicken. This was 2.8 pounds more than the the year 1982 average. By what percent did chicken consumption increase from the year 1982 to the year 1984?

Answers

To solve this, we need to use the z statistic. The formula for z score is:

z = (x – u) / s

where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2

z = (90 – 90.6) / 17.2

z = -0.035

From the standard distribution tables:

P (z = -0.035) = 0.4860

Therefore there is about 48.60 % chance that it will be less than 90 pounds

Answer:

I think it increased by 0.05.

Step-by-step explanation:

If you subtract 2.8 from 55.7 you'll get 52.9. So I would divide 55.9 by 52.9 and get 1.05. I then would subtract 1.0

trigonometry problem​

Answers

Answer: -3π/2

Step-by-step explanation:

The unit circle is tricky, but here are some things to know:

When measuring angles, you usually move in the counter-clockwise direction. If you are moving clockwise (like shown in your picture), the angle will be negative. The unit circle is typically measured in radians, not degrees

              - To convert from radians to degrees, multiply by 180/π

              - To convert from degrees to radians, multiply by π/180

The whole unit circle measures 2π (360 degrees). This means that the positive x-axis can be referred to as 0 or 2π, the positive y-axis is referred to as π/2, the negative x-axis is referred to as π, and the negative y-axis is referred to as 3π/2.

              -If the angle is negative, switch the signs of the axis above.

The information above is all you need to answer the above question, but if you want/need anything else on the unit circle, just let me know.

Answer:

UT = 8

Step-by-step explanation:

From the picture, we can make the following equation...

5 + 2x - 6 = x + 6

By solving it we get

5 + 2x - 6 = x + 6

2x - 1 = x + 6

2x = x + 7

x = 7

Therefor if UT = 2x - 6, then UT is equal to...

2x - 6 = UT

2(7) - 6 = UT

14 - 6 = UT

8 = UT

2y=8-21

2y=-13

y=-13/2

Answer:

y = -6.5

Step-by-step explanation:

simplify: 7y+21=5y+8

put like-terms together and simplify: 2y=-13

(like-terms: 7y-5y=8-21)

divide both sides by 2: y=-6.5

4. Your job as a carpenter pays $20/hour and you worked 40 hours last week. The taxes
withheld from your wages were $83 federal tax and $19 state tax. Your total check is
a. $698
b. $720
c. $810
d. $912

Answers

Answer:

698.00 (A)

Step-by-step explanation:

20.00x40=800.00

83.00+19.00=102.00

800.00-102.00=698.00

The total amount of the check will be $698. Then the correct option is A.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Your job as a carpenter pays $20/hour and you worked 40 hours last week.

Then the amount that you earn in 40 hours will be

⇒ $20 x 40

⇒ $800

The taxes withheld from your wages were $83 federal tax and $19 state tax. Then the total amount of the check will be

⇒ $800 - $83 - $19

⇒ $800 - $102

⇒ $698

The total amount of the check will be $698. Then the correct option is A.

marble will be blue and the second marble will be red?
A: 3/16 B: 6/25 C: 1/8 D : 12/45
Independent or Dependent:
Final Answer:

Answers

Answer:

A

Step-by-step explanation:

Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.
