Answer:

30%

Step-by-step explanation:

<u>Given the following data;</u>

Old value = 200

New value = 260

We will calculate the change using;

Change = new \; number  -  old \; number

Substituting the values, we have;

Change = 260 - 200

Change = 60

Mathematically, percentage change is given by the formula;

Percentage \; change = \frac{increase}{original \; number} * 100

Substituting into the equation, we have;

Percentage \; change = \frac{60}{200} * 100

Percentage \; change = 0.3 * 100

Percent change = 30%

Therefore, the percent change is 30%

Write an exponential growth function to model the situation. A population of 422,000 increases by 12% each year.
Naya [18.7K]
This is just like working with money in a bank account
that's earning 12% interest.

If the population is 422,000 today, and
' n ' is the number of years after today,
then

         Population  =  422,000 (1.12)ⁿ .

20 Points + Brainliest for the answer and Explanation!!!

Answer:

P+Q=5x^2+4

Q-P=-x^2-4x+16

Step-by-step explanation:

We are given

P=3x^2+2x-6

Q=2x^2-2x+10

Calculation of P+Q:

P+Q=3x^2+2x-6+2x^2-2x+10

now, we can combine like terms

P+Q=3x^2+2x^2+2x-2x+10-6

P+Q=5x^2+0+4

P+Q=5x^2+4

Calculation of Q-P:

Q-P=2x^2-2x+10-(3x^2+2x-6)

Firstly, we will distribute negative sign

Q-P=2x^2-2x+10-3x^2-2x+6

now, we can combine like terms

Q-P=2x^2-3x^2-2x-2x+6+10

Q-P=-x^2-4x+16
