Answer:
64 i suppose is the answer.....
Step-by-step explanation:
answer : [0,64]
The height of a model rocket in feet, h(t), as a function of time t in seconds is shown in the graph.
Range is the y value that is the height of the model rocket in feet.
From the graph we can see that the maximum height of the graph is 64
It means the maximum height is 64 feet. Height cannot be negative.
So the height of the function is from 0 to 64
Hence the range of the function h(t) is [0, 64]
The probability of getting a 4 is 1/6, because there are 6 sides in one dice.
You have two vectors: 
and 
In order to find the sum 
of vectors 
and 
, you should add corresponding coordinates:
Answer: correct choice is C.
The discriminant of the function would be negative
