Answer:
The distance travelled by ball is 98 units before it again reaches the same height from which it was thrown.
Step-by-step explanation:
The given parabolic equation is
Where, h is height of ball after covering x distance horizontally.
Put x=0, to find initial height of the ball.
Put y=5.5 in the given equation and find the values of x at which the height of ball is 5.5.
Take square root both sides.
The height of ball is 5.5 at x=0 and x=98.
Therefore distance travelled by ball is 98 units before it again reaches the same height from which it was thrown.
Answer:
12
Step-by-step explanation:
16 divided by 4 is 4
so if he's done 3/4 of his report
he's written 12 pages so far

hope this helped
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can write this rate as an ordinary differential equation.
Where a is proportional constant, P the population variable, and t the time.
Integrating each side of the equation.
To find C we need to use the initial condiction, it means evaluae P at t=0.
Now, we use the sentence the population has doubled in 5 years.
We can find "a" in this condition.
Finally, let's find how long will it take to triple.
I hope it helps you!
To solve, simply do this:
Then you'll get the answer, -7/16
