Answer:
0.5 < t < 2
Step-by-step explanation:
The function reaches its maximum height at ...
t = -b/(2a) = -16/(2(-16)) = 1/2 . . . . . . where a=-16, b=16, c=32 are the coefficients of f(t)
The function can be factored to find the zeros.
f(t) = -16(t^2 -1 -2) = -16(t -2)(t +1)
The factors are zero for ...
x = -1 and x = +2
The ball is falling from its maximum height during the period (0.5, 2), so that is a reasonable domain if you're only interested in the period when the ball is falling.

<u>Answer:</u>
<u>Solution:</u>
Given: x=30
To solve:
On substituting the value of x,
On dividing 30 and 5 we get,
So, the option is 15.
This is a working backwards question.
Since the golf ball was 45g, and the bag was 1.8kg,we need to make them the same units.
45g= 0.45kg
1.8kg= 1.8kg
Now that the units are the same, we put it in a calculator.
1.8÷0.45= 4
Therefore, there are 4 golf balls in the bags.
We can check this by doing 4×0.45= 1.8
Hope this helped!
