We take the equation <span>d = -16t^2+12t</span> and subtract d from both sides to get
0<span> = -16t^2+12t - d
We apply the quadratic formula to solve for t. With a = -16, b = 12, c = -d, we have
t = [ -(12) </span><span>± √( 12^2 - 4(-16)(-d) ) ] / [2 * -16]</span>
= [- 12 ± √(144-64d) ] / (-32)
= [- 12 ± √16(9-4d)] / (-32)
= [- 12 ± 4√(9-4d)] / (-32)
= 3/8 ±√(9-4d) / 8
The answer to your question is t = 3/8 ±√(9-4d) / 8
<u>Hello:</u>
<u />
<u>Okay, this problem should be taken in a series of steps</u>:
<u>What is the slope's formula?</u>

- (x₁,y₁) -- first point
- (x₂,y₂) -- second point
<u>Okay, now let's use this knowledge</u>
10. (5,-19) and (-5,21)

11. (12,1) and (12, -1)

12. (8,7) and (4,7)

<u>Answer:</u>
- Question 10: -4
- Question 11: undefined
- Question 12: 0
Hopefully that helps!
Well, I'm not sure what units "0.5" apply to, but to find the distance he rode, you will need to multiply.
0.5 * 24 = 12.
Barry rode his scooter for a distance of 12 [insert units here].
Hope this helps! Have a great day :)
Answer:

Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is

Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-

So, the distance between marker is

Now, we have to convert this into mixed number.
Then, the distance is-

1.403 > 1.1
1.1 = 1.100
1.403>1.100
