A person throws a key with an initial vertical velocity of 16 feet per second from a building that is 23 feet tall. Use the vertical
motion model, h= -16ť+ vt +s where v is the initial
velocity in feet per second and s is the height in feet, to
calculate how long the key will be in the air for. Round your
answer to the nearest tenth.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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|
