22. The height of a projectile as a function of time is modeled by the function h(t) = -2.5t2 + 5t +
6 where t is the number of seconds after the
projectile was launched and h is the height in feet.
After how many seconds is the ball 6 feet above
the ground? Round the nearest hundredth.

3, nah jk it's 2

step-by-step explanation:

it is 3 cause i'm sanic

correct answer:

i^31 = -i

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
