Answer:
0.125 seconds.
Step-by-step explanation:
We have been given that the height of a ball above the ground as a function of time is given by the function
, where h is the height of the ball in feet and t is the time in seconds.
We can see that our given equation is a downward opening parabola as its leading coefficient is negative. The maximum point will be vertex of parabola.
To find the time, when the ball would be at its maximum height, we need to find the x-coordinate of vertex.
Using formula
, we will find the x-coordinate of vertex of parabola as:





Therefore, the ball will be at a maximum height after 0.125 seconds.

Step-by-step explanation:
- The brackets just mean to multiply
- e.g. 3(2)(5) is the same as 3 × 2 × 5
- When you get the answer, find in in the boxes below and write the letter of that equation
- I will not go through each question separately because it would take too long, but will give you the words
Answer:
solve the inequality /2x-1/≥3
If you are talking about pi/4 radians then that would be 45 degrees because pi in radians is 180 degrees.
