1. The perimeter of the square is f(x) = 4x, where x is the side of the square. Find the domain of the function.
Mkey [24]

If the perimeter of the square is 4x then the domain of the function will be set of rational numbers and the domain of the function y=3x+8(3-x) is set of real numbers.

Given The perimeter of the square is f(x)=4x and the function is y=3x+8(3-x)

We will first solve the first part in which we have been given that the perimeter of the square is 4x and we have to find the domain of the function.

First option is set of rational numbers which is right for the function.

Second option is set of whole numbers which is not right as whole number involves 0 also and the side of the square is not equal to 0.

Third option is set of integers which is not right as integers involve negative number also and side of square cannot be negative.

Hence the domain is set of rational numbers.

Now we will solve the second part of the question

f(x)=3x+8(3-x)

we have not told about the range of the function so we can put any value  in the function and most appropriate option will be set of real numbers as real number involve positive , negative and decimal values also.

11) the difference between the product of 4 and a<br><br> number and the square of the number
marta [7]

Answer:

= 4x-x^2\\\\

Step-by-step explanation:

Let the number be x;

The product of 4 and the number will be;

= 4 * x\\\\= 4x

The the square of the number is given as;

= x^2\\

Taking the difference of both expressions above;

= 4x-x^2\\\\

Factor out the common term:

= x(4-x)\\\\

Hence the difference between the product of 4 and a  number and the square of the number is = 4x-x^2\\\\

Imagine you find a property with a market value of $330,000, and the seller agrees tosell it to you for $275,000. You flip the p
Taya2010 [7]

First let's calculate the profit in the deal, subtracting the market value and the selling value:

330000-275000=55000

So the profit is $55,000.

Now, calculating the fee of 10% of the profit, we have:

10\text{\% of }55000=0.1\cdot55000=5500

So the fee is $5,500, therefore the correct option is the fourth one.
