HW HELP ASAP PL If a projectile is launched into the air from the ground with an initial velocity of 192 feet per second, how long after launch will the projectile be at a height of 256 feet? Show your work.

Can you use your previous answer to determine how long it will take for the object to reach its maximum height? If so, determine how long it will take and find the maximum height.

How long after launch will the projectile land on the ground? Show your work.

Can you use your previous answer to determine how long it will take for the object to reach its maximum height? If so, determine how long it will take and find the maximum height.

How long after launch will the projectile land on the ground? Show your work.

Below.

Step-by-step explanation:

When provided the initial velocity, and no equation, use

    Use -4.9 for "a" when units is meters.

    Use -16 for "a" when the units is feets

    The initial velocity is the the value of "b"

    If the launch occured from a height (other than the ground), you would add that height as a constant

So, based on given info, here is our equation that models the projectile path:

   h(x) = -16t2 + 192t

   256 = -16t2 + 192t

   0 = -16t2 + 192t - 256

   0 = 16t2 - 192t + 256

   0 = t2 - 12t + 16

   This cannot be factored.

    You can use the quadratic formula, or completing the square, to solve (not shown here)

    Solutions are t =  6 ± 2√5 = 10.47 and 1.53

The height will be at 256 ft after 1.53 seconds and 10.47 seconds

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
