If an object is projected upward with an initial velocity of 126 ft per sec, its height h after t seconds is h= -16^2+126t. find the height of the object after 5 seconds

230 ft  is the height of the object after 5 seconds

Step-by-step explanation:

As per the statement:

If an object is projected upward with an initial velocity of 126 ft per sec.

The height h after t seconds is given by:

We have to find the height of the object after 5 seconds.

At t = 5 seconds

⇒

⇒

Simplify:

h(5) = 230 ft

Therefore, the  height of the object after 5 seconds is, 230 ft

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
