Brianna tossed a basketball in the air. The height of the ball, h(t), in terms of the elapsed time since the ball was tossed, t, can be represented by the function below. h(t) = –16t2 + 16t + 6
What are a reasonable domain and range for the problem situation?

1.Domain: 0 ≤ t ≤ 10
Range: 0 ≤ h(t) ≤ 1.3

2.Domain: t ∈
Range: h(t) ≤ 10

3. Domain: –0.29 ≤ t ≤ 1.3
Range: 0 ≤ h(t) ≤ 10

4. Domain: 0 ≤ t ≤ 1.3
Range: 0 ≤ h(t) ≤ 10

Julia chooses a card at random from her set of cards. what is the probability that the card is labeled cat or hamster?

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
