3. Rewrite the expression as simply as you can:
3x + 11y - 2x - 4y

Answers

Answer:

x+7y

Step-by-step explanation:

First off, lets split the question into both x and y.

3x - 2x for the x

11y - 4y for the y

You can solve both of them to get x + 7y

3x - 2x = x

11y - 4y = 7y

Then, add them back up and get x + 7y

Answer:

x+7y

Step-by-step explanation:

3x + 11y -2x - 4y

(3x) + (11y) + (-2x) + (-4y)

(3x) + (-2x) = x

(11y) + (-4y) = 7y

3x + 11y -2x - 4y = x + 7y

The fox population in a certain region has a continuous growth rate of 6 percent per year. It is estimated that the population in the year 2000 was 19100.
(a) Find a function that models the population t years after 2000(t=0 for 2000).
Hint: Use an exponential function with base e.
Your answer is P(t)=

(b) Use the function from part (a) to estimate the fox population in the year 2008.
Your answer is (the answer must be an integer)

Answers

Answer

[tex] P(t) = 19100. e^{0.06t} [/tex]

b) P(8) =30866

Step-by-step explanation

Use formula:

[tex] P(t) = P. e^{rt} [/tex]

Here, P = 19100

r = 6% = 0.06

[tex] P(t) = 19100. e^{0.06t} [/tex]

b) t = 2008 - 2000 = 8

[tex] P(8) = 19100. e^{0.06\times 8} [/tex]

[tex] P(8) = 19100. e^{0.48} [/tex]

[tex] P(8) = 19100\times 1.616\\\\

P(8) = 30,865.6\\\\P(8) \approx 30,866[/tex]

4.) Are imperfect square roots rational or irrational?

Answers

Answer:

Irrational

Step-by-step explanation:

Answer:

Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).

Answers

Answer:

B. 13

Step-by-step explanation:

5 + 4 × 2 = 13

The correct option is (B).

What is PEMDAS rule?

PEMDAS: Order of Operations

P: Solve the calculation or equation which are present in the parentheses or brackets like small brackets( ), curly brackets{ } or big brackets[ ]. Priority is given to brackets first.

E: Exponential expressions should be calculated first before the operations of multiplication, division, addition and subtraction.

MD: Then perform multiplication or division from left to right, whichever comes first in the equation.

AS: At last, perform addition or subtraction whichever comes first while moving from left to right.

Given expression,

5 + 4 × 2

According to order of operations:

Solving multiplication operation:

5 + 8

Now solving addition operation

= 13

Hence, after applying order of operations, the value of expression is 13.
