Answer:
The answer is:
{(2,2),(4,4),(6,6),(8,8)} is a function
{(0,3),(3,5),(5,6),(8,4)} is a function
{(1,2),(3,3),(4,8),(6,3)} is a function
{(3,4),(5,2),(5,6),(7,3)} is not a function
Step-by-step explanation:
Sorry I don't have an explanation, but I know these are correct because I took the test and got this correct. ;)
1 function {(2,2),(4,4),(6,6),(8,8)} written is a function the other following coordinates are not functions due to it not being a straight line as a 'proper' function should be.
42.06 ft²
2 sides = 2(2.7 ft × 3.2 ft) = 2 × 8.64 ft² = 17.28 ft²
Front + back = 2(2.1 ft × 3.2 ft) = 2 × 6.72 ft² = 13.44 ft²
Top + bottom = 2(2.1 ft × 2.7 ft) = 2 × 5.67 ft² = <u>11.34 ft² </u>
Total area = 42.06 ft²
a - 48
12 cups are divided into 1/4 cup bags.
Converting 12 into a fraction, you get:
12/1 divided by 1/4.
When we divide fractions, we flip the second fraction and change the operation to multiplication.
12/1 * 4/1.
Since 12/1 and 4/1 are now just whole numbers, (12 and 4), we can multiply them together.
12 * 4 = 48.
54.
(self-explanatory.)
64
A square has equal side measurements meaning that each side is 8. To find the area, multiply the length by the width which would be 8 * 8 = 64.
