Answer:

Domain = all real numbers

Step-by-step explanation:

The domain of a function is the set of x-values for which the function is defined.

When we have a graphical representation of a function, we look if the function is continuous for all values of x or not. If it is, the domain is the set of all real numbers. If it is not, we look from what value till what value the function is defined for , x-values basically.

Looking at this function, we see that it stretches forever to the left and forever to the upward direction (also advancing right limitless as well).

We want the domain (x values), which concerns with LEFT and RIGHT. So, we can see that this function is continuous for all values of x (it goes on and on to right and left). So we can say the domain is the set of all real numbers.

Domain = all real numbers

Answers

3(1)/(4)*(-2(3)/(5))= (13)/(4)*(-(13)/(5))=-(13*13)/(4*5)=-(169)/(20)=-8(9)/(20)
3(3)/(4)\cdot(-2(3)/(5))=(3\cdot4+1)/(4)\cdot\left(-(2\cdot5+3)/(5)\right)=(13)/(4)\cdot\left(-(13)/(5)\right)=-(13\cdot13)/(4\cdot5)=-(169)/(20)=-8(9)/(20)\n\n\nAnswer:A

A store makes a profit of $8 on a sweater after a markup of 40%. What is the selling price of the sweater?

Answers

Use ratios: (40)/(100)(8)/(7)

Since 40/8=5, then you do the same on the bottom. 100/5=20, so the sweater was originally $20.

How many blocks with dimensions of 1/3 x 1 x 1 can fit in a unit cube? A. 2 B. 3 C. 6 D. 9

Answers

a block of (1/3) x 1 x 1, has a volume of, just that product, namely 1/3.

a Unit Cube, has all sides of 1 unit, thus called the Unit cube, and has a volume of 1*1*1 = 1³ = 1.

so, how many times does the volume of 1/3 go into 1?

recall there are three thirds in a whole, so 1/3 + 1/3 + 1/3 = 1, 3 times.
