Answer:
The ball will reach the ground when h=0.
Set the equation equal to 0.
Step-by-step explanation:
The height of a golf ball after it has been hit from the top of a hill can be modeled by the equation
,
where h is the height in feet and t is time in seconds.
When ball will reach the ground the distance between ball and ground is 0. So, the ball will reach the ground when h=0.
To find the time it takes for the ball to reach the ground, set the equation equal to 0 and use the Zero Product Property to solve for $t$.
Solve the equation using the Zero Product Property.
So,
Answer:
y=-2x+3
Step-by-step explanation:
Comment if you need steps.
1/2*bh=75
1/2*bb=75
b^2=150
b=rt(150)=12.2
not sure what you mean by link, but 12.2 is approximately the length you're seeking
Is it a chair? if so it's 7
Answer: Step E
Step-by-step explanation:
The error is in the last step. In Step D, we see that we're supposed to subtract the second part from the first part. We also see we have the terms 2x-8 in the numerator on the right. Since we're subtracting, the expression should actually be -2x +8. 3 -2x +8 should be -2x +11 which is not the numerator in Step E so the last step is wrong.
