Answers

I'll do the first 6 rows to get you started.

===========================================

In row 1, we have the number [tex]2^3[/tex] which is the same as writing 2^3

The base is 2 and the exponent is 3. Think of "base" as in "basement" to remember that the base is under the exponent. The exponent tells us how many copies of the base to multiply out. In this case, we have three copies of the base "2" multiplied to get 2*2*2 = 8

============================================

In row 2, we have the number 3^2. The base is 3 and the exponent is 2.

We can say 3^2 = 3*3 = 9. We have two copies of the base multiplied. Think of a 3 inch by 3 inch square that has area of 9 square inches.

============================================

Row 3:

The number 5^4 means 5^4 = 5*5*5*5 = (5*5)*(5*5) = 25*25 = 625

The base is 5 and the exponent 4 tells us how many copies of the base to multiply.

============================================

Row 4:

We aren't given the number like in the earlier rows. But we can see that the base is 6 and the exponent is 2. So the number to fill in that first blank is 6^2

The expanded notation would be 6*6 because the exponent tells us how many copies of the base to multiply out.

The standard notation is 36 because 6*6 = 36.

============================================

Row 5:

This time we don't have an exponent, but we have the base and we have the expanded notation.

The expanded notation of 8*8*8 means the base is 8 and the exponent is 3

So 8^3 = 8*8*8 = 512

We'll have 8^3 to fill in the first blank of row five, 3 fill in the next blank, and finally 512 fill in the last blank.

============================================

Row 6:

We have six copies of '9' multiplied together

This tells us we have the number 9^6. The base is 9 and the exponent is 6

Use your calculator to determine that 9^6 = 9*9*9*9*9*9 = 531441

============================================

I'll let you do the rest of the remaining rows.

Tyler has $125.00 to spend on books and CDs. He buys one book for $30.00. He wants to spend the rest on CDs that are on sale for $9.00 each. Which of these statements is true?
a.He can't buy any CDs.

b.He can buy 11 CDs.

c.He can buy more than 11 CDs.

d.He can buy 10 CDs.

Answers

Answer:

d. He can buy 10 CDs

Step-by-step explanation:

The reason he can only buy 10 is because if the CDs are $9.00 each then you would multiply:

                     10 x 9 = $90.00

If you add the $30.00 of books:

                     $90.00 + $30.00 = $120.00

This means he does not have enough money to buy another CD. He has $5.00 left over.

Michael has a points card for a movie theater. He receives 70 rewards points just for signing up. He earns 8.5 points for each visit to the movie theater. He needs at least 165 points for a free movie ticket. What is the least number of visits he needs to make in order to earn a free movie ticket?

Answers

Answer

The true least number of visits is the lowest whole number above 11.176470..., which is 12.

Step-by-step explanation:

points per visit, # of visits + sign-up points ≥ free tickets points

8.5 (points per visit)  

70 (# of visits)

165 (free ticket points)

8.5v ≥ 70 + 165

70 + 8.5v ≥ 165

8.5v ≥ 165 -70

8.5v/8.5v ≥ 95/8.5

v ≥ 11.1764705882

The true least number of visits is the lowest whole number above 11.176470..., which is 12.

Step-by-step explanation:

The end behavior of a function f ” describes the behavior of the graph of the function at the “ends” if the x-axis.

In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞) and to the left end of the x-axis (as x approaches -∞).

WHAT ARE THE PRINCIPALS PLEASE HELP ME!

You have 2 different savings accounts. For Account​ A, the simple interest earned after
6 months is ​$4.63. For Account​ B, the simple interest earned after 21 months is ​$16.80. If the interest rate is ​3.7% for Account A and ​2.4% for Account​ B, how much is the principal in each​ account? Which account earned you the most interest the first​ month? Explain your answer.

Answers

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount of money invested.

R represents interest rate

T represents time

Considering the investment on account A,

I = $6.94

R = 3.7%

T = 9 months = 9/12 = 0.75 years

6.94 = (P × 3.7 × 0.75)/100 = 0.02775P

P = 6.94/0.02775 = $250

Considering the investment on account B,

I = $13.80

R = 2.3%

T = 18 months = 18/12 = 1.5 years

13.8 = (P × 2.3 × 1.5)/100 = 0.0345P

P = 13.8/0.0345 = $400

To determine the account that earned more interest in the first month,

250/9 = $27.8

400/18 = $22.2

Account A earned you the most interest the first​ month because $27.8 is higher than $22.2

5. Solve the equation - 4(x - 1) + 6x = 2(17 -- x) for x.

Answers

Answer:

x = 15/2 or 7.5

Step-by-step explanation:

-4 (x - 1) + 6x = 2(17 - x)

First, distribute the -4 and 2, and remember that multiplying two negatives make a positive.

-4x + 4 + 6x = 34 - 2x

Combine like terms

2x + 4 = 34 - 2x

Subtract 4 from both sides

2x = 30 - 2x

Add 2x to both sides

4x = 30

Finally, divide both sides by 4

x = 15/2 or 7.5
