Answer:
about 5.613 seconds
Step-by-step explanation:
Using the quadratic formula to find the value of t when h = 0, we have ...
at² +bt +c = 0
t = (-b±√(b²-4ac))/(2a)
t = (-72±√(72² -4(-16)(100)))/(2(-16))
t = (-72±√11584)/-32 = (9±√181)/4
Only the positive value of t is of interest.
The coin will hit the stream after (9+√181)/4 seconds ≈ 5.613 seconds.
Answer:Multiply the denominator on the bottom of the fraction by the whole number you are dividing by.
To divide a fraction by a whole number, multiply the bottom of the fraction by this whole number.
The denominator on the bottom of the fraction is 7.
We will multiply 7 by 2.
7 × 2 = 14 and so, 6 / 7 ÷ 2 = 6 / 14 .
