If a projectile is launched vertically upward from 800 ft above the ground with an initial velocity of 80 ft per second, its hei

Hello!

10 seconds to return to the ground.

7 seconds to reach 576 feet above the ground.

Find the amount of time taken to reach the ground by setting the equation equal to 0:

0 = -16t² + 80t + 800

Factor out -16 from the equation:

0 = -16(t² - 5t - 50)

Factor the terms inside of the parenthesis:

0 = -16(t - 10)(t + 5)

Find the zeros:

t - 10 = 0

t = 10

t + 5 = 0

t = -5

Time can only be positive in this instance, so the correct answer is 10 sec.

Find the time by substituting in 576 for the height:

576 = -16t² + 80t + 800

Subtract 800 from both sides:

-224 = -16t² + 80t

Rearrange:

0 = -16t² + 80t + 224

Simplify:

0 = -16(t² - 5t - 14)

0 = -16(t - 7)(t + 2)

t = 7 seconds.

Fill in the blanks:

ser-zykov [4K]

Answer:

$8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$

So in blanks there will be 8, 9, 4, 3

Step-by-step explanation:

We have given that $8943=.....\times 1000+....\times 100+....10+....1=....10^3+....10^2+....10^1+....1$

We have to fill the blanks

We know that $8\times 1000=8000$

$9\times 100$

$4\times 10$

$3\times 1$

When we add all then

$8000+900+40+3=8943$

So in the blanks there will be 8 , 9, 4 , 3

We also know that $8000=8\times 10^3$

$900=9\times 10^2$

$40=4\times 10^1$

$3\times 1=3$

So $8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$
