Step-by-step explanation: because you simplify
Differentiate to find time that gradient=0
45-9.8t=0
45=9.8t
t =4.59 secs
put this value into original equation to get 103.31

Answer:
x = 5.5 to the nearest tenth.
Step-by-step explanation:
Here we have a right triangle with one angle (65 degrees) given. Side x is the "side adjacent to the angle" and is to be found. The hypotenuse is 13.
The cosine function makes use of these three knowns: the angle, the hypotenuse and the adjacent side. Thus:
cos 65 degrees = adj / hyp = x / 13, or
x = 13 cos 65
Evaluating this on a calculator, we get x = 5.49, or x = 5.5 to the nearest tenth.
Answer:
Odd
Step-by-step explanation:
The function is odd because cubic functions are always odd.
