How do you write an area?

Mathematics
1 answer:
murzikaleks [220]1 year ago
5 0

To write an area, you need to know the shape and the measurements of the sides.

For example, if you have a square, you can calculate its area with the formula A = s², where A is the area and s is the length of a side.

If the side is 10 cm, then the area would be written as A = 10² = 100 cm².

1. Identify the shape of the area you are trying to calculate.

2. Calculate the measurements of the sides.

3. Use the appropriate formula to calculate the area. For example, for a square, use the formula A = s², where A is the area and s is the length of a side.

4. Plug in the measurements and calculate the area.

5. Write the area using the correct unit of measurement. For example, if the side was 10 cm, the area would be written as A = 10² = 100 cm².

Suppose the population of a town is 2,700 and is growing 4% each year. A. Write an equation to model the population growth. B. P
miss Akunina [59]

Answer:

Third option i.e. A. 2700(1.04)^x and B. About 4,323 people

Step-by-step explanation:

We are given that,

Initial population of the town = 2,700

The rate of growth = 4% = 0.04

Part A: Since, the equation for the growth is given by,

Population growth = P(1+r)^x, where P is the initial population, r is the rate of growth and x is the time period of growth.

We have, according to the question,

Population growth = 2700(1+0.04)^x

i.e. Population growth = 2700(1.04)^x

Thus, the equation for the population growth is 2700(1.04)^x.

Part B: Now, it is required to find the population after 12 years i.e. x= 12.

So, we have,

Population = 2700(1.04)^x

i.e. Population = 2700(1.04)^{12}

i.e. Population = 2700\times 1.601032

i.e. Population = 4,323

Hence, the population after 12 years is 4,323 people.

Thus, the third option is correct.

Which product of prime polynomials is equivalent to 3x4 – 81x?
aleksley [76]

Answer:

3x(x – 3)(x2 + 3x + 9)

Step-by-step explanation:

Because 3x4 – 81x=3x4-3x3

and the formula is

a3-b3=(a-b)(a2+ab+b2)

but since here it is 3x4 we put 3x before the formula.
