A diver launches herself off a springboard. The height of the diver, in metres, above the pool 1 seconds after launch can be modelled by the following function:
h(1) = 51 - 101 + 10,10
a How high is the springboard above the water?
(1 mark)
b Use the model to find the time at which the diver hits the water.
(3 marks)
< Rearrange h(t) into the form A - B(1-C) and give the values of the constants
A, B and C
(3 marks)
Using your answer to parte or otherwise, find the maximum height of the diver, and
the time at which this maximum height is reached.

b. x- 48 =120

step-by-step explanation:

the line of

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
