Complete the first table so that f(x) is a function.

netineya [11]

For f(x) to be a function, the value of x should not be repeated. That is no x value can be more then once.

So the required table is

$x \ \ \ \ \ f(x) \\ -1 \ \ \ \ \ \ 2 \\ 2 \ \ \ \ \ -8 \\ 6 \ \ \ \ \ -12$

And for g(x) , not to be a function, we have to repeat x value that is

$x \ \ \ \ \ \ g(x) \\ -1 \ \ \ \ \ \ 2 \\ -1 \ \ \ \ \ \ -8 \\ 6 \ \ \ \ \ \ -2$

Don’t remember how to do this , ?

28. The ratio of games they won to total games played = 12: 14 = 6: 7.

29. Max's pay rate is 9.50 dollars per hour.

30. The value of n is 9.

Step-by-step explanation:

Step 1; Heather's team won 12 games out of 14. To find the ratio of games won to the total number of games we divide the number of games won to the number of games played.

The ratio of games won to games played = 12: 14, dividing both sides by 2 we simplify the ratio. So the simplified ratio is 6: 7.

Step 2; Max earns $380 for working 40 hours. So to find how much he earns an hour we divide the total money earned in n hours divided by n number of hours.

Money earned per hour = $\frac{380}{40}$ = $9.50. So Max's pay rate per hour is $9.50.

Step 3; The given proportion is

$\frac{n}{12}$ = $\frac{18}{24}$ , to solve this we keep n on the left-hand side while we multiply the 12 on to the other side

n = $\frac{18}{24}$ × 12 = $\frac{3}{4}$ × 12 = $\frac{36}{4}$ = 9.

Need help on numbers 1 and 2 ill mark brainliest if they are right

Question author, it's spelled pi not pie, and we use just use the Greek letter π. Students, demand better from your teachers.

1. Rectangular prism, aka a box. Volume is length times width times height.

V = 5×7×9 = 315 cubic feet

That's cubic feet of course, the product of three lengths. We didn't even need to do the problem, just look for the common answer and pick the one with the right units. I just saw that same pattern in a volume problem yesterday.

Answer: 315 cubic feet, first choice

2. Cylinder, volume is base area times height, πr²h. We have a radius of r=14/2=7 yd and h=8 yd. We're using π=3.14.

V = πr²h = 3.14(7²)(8) = 1230.88 cubic yds

Answer: 1230.9 cubic yards, last choice
