Answer:

f(-2) = 13

g(4)  = -9

Explanation:

Whenever a question is asking you to find something like, in this example, f(-2) or g(4), you have to substitute whatever number is in the parentheses for every x in the function with that letter.

Let's try to find f(-2). We have to substitute -2 for every x in the function f and simplify:

f(-2) = -2 (-2)^{3} -3\\f(-2)  = -2(-8)-3\\f(-2) = 16 - 3 \\f(-2)  = 13

Therefore, f(-2) = 13.

Next, let's try to find g(4). We have to substitute 4 for every x in the function g and simplify:

g (4) = -2(4) - 1\\g(4) = -8-1\\g(4) = -9

Therefore, g (4) = -9.

How many positive integers less than 2018 are divisible by at least 3, 11, or 61?
Schach [20]
To find all the positive integers less than 2018 that are divisible by 3, 11, and 61, you will use what you know about factors.

3, 11, and 61 are all answers.  So are 33, 183, 671, and 2013.

If you put these in factors, the product will be divisible by them!

3 x 11 = 33
3 x 61 = 183
11 x 61 = 671
3 x 11 x 61 = 2013

Take each number and square it, cube it, etc...
9, 27, 81, 243, 729
121, 1331

9 x 11 = 99
27 x 11 = 297
81 x 11 = 891

121 x 9 =1089
121 x 3 =  363

61 x 9 = 549
61 x 27 = 1647

Medal award ceremonies are held after each event. The following three flags are used to represent the gold, silver, and bronze m
LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Having the information on how many events there are and how many people in each event there would help me personally solve this

what i can tell you is its a probability thing a tree diagram is starting with something, like flipping a coin, and creating a branch for heads and tails, 0.5 for each branch. like the attachment I have on here. there's only 2 probable results from a coin, but if I have 5 events with 50 competitors I've created a lot more probable outcomes, it also depends on the events, if one of my competitors in 6'9" and ones 5'2" and the event is a dunk contest it would be slightly unfair and the probability of the person who is 5'2" changing your tree diagram :)
