Let

x-------> the number of persons in the family

f(x)------> the function represent the cost of living

we know that

The domain of the function would only include positive integers, because the number of persons can not be negative or a fraction

The range of the function would only include positive numbers, because the cost can not be negative

therefore

<u>the answer is the option B</u>

The domain would only include positive integers.

We are asked to <span>represent the costs of living per person in the family. Integers are natural numbers including the positive and negative ones. The costs of living can be expressed in whole numbers or accurately numbers with decimals. Hence, the answer to this problem is C.</span>

What are the coordinates of the endpoints of the mid segment of triangle ABC that is parallel to line AB?

MrMuchimi

Answer:

$(4.5,4)$ and $(4.5,6.5)$

Step-by-step explanation:

we have the coordinates

A(2,7),B(2,2),C(7,6)

we know that

The mid segment of triangle ABC that is parallel to line AB is located between the mid point AC and the mid point BC

The formula to calculate the midpoint between two points is equal to

$(\frac{x1+x2}{2},\frac{y1+y2}{2})$

step 1

Find the mid point AC

we have

A(2,7),C(7,6)

substitute in the formula

$(\frac{2+7}{2},\frac{7+6}{2})$

$(4.5,6.5)$

step 2

Find the mid point BC

we have

B(2,2),C(7,6)

substitute in the formula

$(\frac{2+7}{2},\frac{2+6}{2})$

$(4.5,4)$

therefore

The endpoints of the mid segment of triangle ABC that is parallel to line AB are $(4.5,4)$ and $(4.5,6.5)$

Which simplified fraction is equal to 0.53 with bar?

Oxana [17]

I assume that 0.53 with a bar means the decimal fraction in which 3 is repeating.

24/45, 8/15, and 48/90 all result in the same decimal value. Thus, we are simply looking for the one that is fully simplified.

The correct answer is 8/15.

Hope this helps!
