The flight of one type of flare at the symphony of fire is described by the formula H= -3 (T -1.5)^2+21 where age is the height of the rocket in metres and T is the time in seconds after the rocket was fired. A) What was the max height of the rocket and when did it reach max height?
B) find the height of the ticket at 2.5 secs
C) how many seconds after the rocket was fired did it hit the ground?

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

-3 degrees
