long. How long was it at first?

Answers

It was originally 50 inches long.

Let’s call the original length L
L - 10 = 40
Add 10 to both sides of the equation
L = 50

Step-by-step explanation:

1.Assume that 20 squirrels are put in an enclosed wildlife ranch and the squirrel population grows for the next 5 years, as shown in the table.

Year

Rabbit Population

0

20

1

80

2

320

3

1280

4

5120

5

20,480
Write a function that represents this.

2.A second group of 20 squirrels of a different breed is placed on a different ranch. The population of squirrels triples each year. Write an equation to model this situation.

3.Had the second group started with 40 squirrels instead of 20, which population will be bigger by year 3 and by how much?

Answers

Answer:

For the first group we have the pairs:

year population

0 20

1 80

2 320

3 1,280

4 5,120

5 20,480

Here we can see that the population quadruples each year

(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)

then the population equation is:

P(0) = 20

P(1) = 20*4

P(2) = (20*4)*4 = 20*4^2

We already can see the pattern, then we can write this relationship as:

P(t) = A*(4)^(t)

Where:

t represents time in years, and A is the initial population, that we know it is 20, then:

P(t) = 20*(4)^t

This is the function that represents the table.

B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:

Q(t) = 20*(3)^t

C) Now, if the initial population of the second group is 40, the equation becomes:

Q(t) = 40*(3)^t

The population by year 3 is given by replacing t by 3, then:

Q(3) = 40*(3)^3 = 1080

And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:

1,280 - 1,080 = 200

So the first group is larger by 200 squirrels.

A teacher wrote the following set of numbers on
the board:
20 b = 2.5
Explain why a +b is irrational, but b + c is rational.
a= V20
C= 225

Answers

Answer:

Did you copy this down correctly?

Step-by-step explanation:

b = .125 which is rational

a is irrational because the square root of a prime number is irrational.

If c = 225....

then adding 2 rational numbers = rational sum

But adding (or multiplying) an irrational number to a rational number = irrational number.

The a +b is irrational because the sum of rational and irrational number is 'a' irrational number and b + c is rational because adding two rational number is rational, as c is the rational number.

What is an irrational number?

It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words the irrational number cannot be expressed in the form of p/q form.

A rational number is a sort of real number that has the form p/q and does not equal zero.

We have:

20b = 2.5

b = 0.125

a = √20

c = 225

= a + b

= √20 + 0.125

Here 'a' is irrational because the square root of a prime number is irrational.

And b is the rational number

The sum of rational and irrational number is 'a' irrational number.

= b + c

= 0.125 + 225

b = 0.125 which is rational

Adding to rational number is rational, as c is the rational number.

Thus, the a +b is irrational because the sum of rational and irrational number is 'a' irrational number and b + c is rational because adding two rational number is rational, as c is the rational number.
