Iam having a hard time figuring this out can some one ! 1
as a scientist, you study 200 grams of radioactive material for several months and you have obtained the following data:

month, weight

0, 500
2, 329
4, 216.1
6, 142
8, 93
10, 61.29
12, 40.3
express the weight as the function of months.

What is the value of x in the equation 1.5x+4-3=4.5(x-2)?

Consider an example of a deck of 52 cards: example set of 52 playing cards: 13 of each suit clubs, diamonds, hearts, and spades ace 2 3 4 5 6 7 8 9 10 jack queen king clubs diamonds hearts spades what is the probability of drawing three queens from a standard deck of cards, given that the first card drawn was a queen? assume that the cards are not replaced.

Which equation represents a direct linear variationa. y=x2b. y=2/5xc. y=1/xd. y=x+3
