Answer:
120ft
Step-by-step explanation:
If the bases are 120ft apart from each other you would have to find the distance of going from first to second then to third. Then you divide it in half because you arent going around the diamond, you are cutting right through it.
Answer: The projectile reaches its maximum height after 20 seconds.
Step-by-step explanation:
Given the function:
![h(t) = -16t^2 + 640t](https://tex.z-dn.net/?f=h%28t%29%20%3D%20-16t%5E2%20%2B%20640t)
You can following formula (which gives the x -coordinate of the vertex of the parabola) in order to find after how many seconds the projectile takes to reach its maximum height:
![x=t=-\frac{b}{2a}](https://tex.z-dn.net/?f=x%3Dt%3D-%5Cfrac%7Bb%7D%7B2a%7D)
In this case you can identify that the values of "a" and "b" are:
![a=-16\\b=640](https://tex.z-dn.net/?f=a%3D-16%5C%5Cb%3D640)
Then, substituting values into the formula, you get the following result:
![t=-\frac{640}{2(-16)}\\\\t=20](https://tex.z-dn.net/?f=t%3D-%5Cfrac%7B640%7D%7B2%28-16%29%7D%5C%5C%5C%5Ct%3D20)
Therefore,based on this, the conclusion is: The projectile reaches its maximum height after 20 seconds.
