describe how to use special product patterns to find 21^2

Answers

Answer 1

Answer:

21 x 21 = 441

Step-by-step explanation:

Whenever there is an exponent that is the many times you multiply the base by itself to.

Answer 2

Power is the result of multiplying two numbers together. The value of 21^2 is 441.

What is power?

Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

Given that 21 has a power of 2, therefore, 21 to the power 2 means that 2 should be multiplied by itself twice.

21^2

= 21²

= 21 × 21

= 441

Hence, the value of 21^2 is 441.

Connor has five nickels in one hand and some dimes in his other hand. He has more than two times as many dimes as nickels. He has fewer than three times as many dimes as nickels.

Answers

Complete question :

How many dimes might he have?

How many coins would he have altogether?

Answer:

11, 12, 13, 14 ;

16, 17, 18, 19

Step-by-step explanation:

Let :

Nickel = n

Dimes = d

Total number of nickels = 5

He has more than 2 times as many dimes as nickels ;

d > 2n

d > 2*5 ; d > 10

He has fewer than 3 times as many dimes as nickels;

d < 3n

d < 3*5 ; d < 15

Meaning he has more than 10 dimes but less than 15.

10 < d < 15

So, d could be ;

11, 12, 13, 14

Number of coins altogether :

11 + 5 = 16

12 + 5 = 17

13 + 5 = 18

14 + 5 = 19

the number of squirrels in a park at the end of the month

Answers

Using the given recursive function, we have that:

a) There will be 132 squirrels in the park at the end of August.

b) As time goes by, the number of squirrels in the park will increase.

What is the recursive function for this problem?


The recursive function for this problem models the number of squirrels in the park at the end of month n+1, considering the amount present at the end of month n, as follows:

[tex]S_{n+1} = 1.6S_n - 30[/tex]

For this problem, we have that at the amount at the end of May is of 70, hence:

[tex]S_{5} = 70[/tex]

Hence, we find the amounts at the end of June, July and August, as follows:

[tex]S_6 = 1.6(70) - 30 = 82[/tex].[tex]S_7 = 1.6(82) - 30 = 101[/tex].[tex]S_8 = 1.6(101) - 30 = 132[/tex].

Hence:

a) There will be 132 squirrels in the park at the end of August.

b) As time goes by, the number of squirrels in the park will increase.

Find the slope of the line through the points (-3,1) and (-1,5).

Answers

Answer:

The slope is 2

Step-by-step explanation:

(-3,1)

+2 ——> (-1,5) <—— +4

m = y/x —> 4/2 —> 2

m = 2

Answer:

[tex]\boxed {\boxed {\sf m=2}}[/tex]

Step-by-step explanation:

The formula for slope is:

[tex]m= \frac {y_2-y_1}{x_2-x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are the points on the line.

We are given the points (-3,1) and (-1,5). Therefore,

[tex]x_1= -3 \\y_1= 1 \\x_2= -1 \\y_2=5[/tex]

Substitute the values into the formula.

[tex]m= \frac {5-1}{-1--3}[/tex]

Solve the numerator.

[tex]m= \frac{4}{-1--3}[/tex]

Solve the denominator.

-1 --3= -1+3 =2

[tex]m=\frac{4}{2} \\[/tex]

Divide.

[tex]m=2[/tex]

The slope of the line is 2.
