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.

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

a)

[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]

a)

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).

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

Sum = -34

x + (x + 1) + (x + 2) + (x + 3) = -34

x + x + 1 + x + 2 + x + 3 = -34

(x + x + x) + (1 + 2 + 3) = -34

Mason inspects 73.5 phones each day. He must inspect no fewer than 1,470 phones each month. How many days will Mason need to work to reach his goal by the end of the month.

Answers

Answer:

20 days

Step-by-step explanation:

We have 31 days in one month

Mason must have inspected 1470 after 31 days

He inspects 73.5 phones per day. Hence,

73.5 phones =>1 days

1470 phones =>

1470 ÷ 73.5 => 20 days

Hence, Mason will need 20 days to reach his goal.
