Little Frufru is standing at the top of a lighthouse. She is 96 feet above the ocean. She tosses a ball into the air. The height, h, of the ball after x seconds is given by h = - 16t2 +64t +96. How many seconds does it take the ball to land in the ocean? Round to the neaest hundredth

5.16 seconds

Step-by-step explanation:

Think about a graph with h(t) as the y-axis, and t as the x-axis. Meaning at the start (0 seconds) the ball will be at 96 feet in the air (hence the constant/y-int). We want to see when that ball hits the exactly 0 feet. Which means it needs to touch the x-axis. So h(t) must equal 0. We can subtitute this in the equation:

Now we just need to find the factors. First we should make the coefficient 0 by adding everything to the left side:

Now divide both sides by 16:

Now we can Use the complete the square method:

Take have of 4 and then square it and add it to both sides:

Square both sides:

±

±

Then, since it is only positive time you would get:

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
