Step-by-step explanation:

This is a perimeter question. All you have to do is add up all 4 sides together. In that case, it will be 2(3.5x - 7) + 2(x + 0.4). And we have our final answer!

Numbers 11-14 pls I’m having a lot of trouble
Ksivusya [100]

The term "closed" in math means that if you take two items from a set, do some operation, then you'll always get another value in the same set (sometimes you may get the same value as used before). For example, adding two whole numbers leads to another whole number. We therefore say "the set of whole numbers is closed under addition". This applies to integers as well because integers are positive and negative whole numbers. So we can say that integers are closed under addition.

Integers are not closed under division. Take two integers like 2 an 5 and divide: 2/5 = 0.4 which is not an integer. Integers don't have decimal parts.

The set of whole numbers is {0,1,2,3,...} and we can subtract the two values 1 and 2 to get 1-2 = -1. The order matters here. Subtracting a larger value from a smaller leads to a negative. The value -1 is not in the set of whole numbers. So we can say that whole numbers is not closed under subtraction

Finally, the set of irrational numbers is closed under addition. Adding any two irrational numbers leads to another irrational number. For instance, pi+sqrt(2) = 3.142 + 1.414 = 4.556; I'm using rounded decimals as approximate values. An irrational number is one where we cannot write it as a fraction of integers. Contrast that with a rational number in which we can write it as a fraction of integers. Example: 10 = 10/1 is a rational number.

The value of a company in millions of dollars during its first 10 years increased by 2% each year.The original valuation of the
solong [7]

Answer:

Step-by-step explanation:

The rate at which the value of the company increased is exponential.

We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the value of the company after t years.

t represents the number of years.

P represents the initial value of the company.

r represents rate of growth.

From the information given,

P = 2.1 million

r = 2% = 2/100 = 0.02

t = x years

The function to represent the value of the company, x years after being founded is

A = 2.1 × 106(1 + 0.02)^x

Therefore, the worth of the company in 6 years is

A = 2.1 × 106(1 + 0.02)^16

A = 2.1 × 10^6(1.02)^6

2364941

The worth of the company in 2 years is

A = 2.1 × 10^6(1 + 0.02)^2

A = 2.1 × 10^6(1.02)^2

A = 2184840

The difference in worth of the company after 6 years and after 2 years is

2364941 - 2184840 = $180101
