If an object is projected upward with an initial velocity of 129 ft per sec, its height h after t seconds is h equals negative 16 t squared plus 129 t. Find the height of the object after 5 seconds.

  245 feet

Step-by-step explanation:

Put 5 where t is in the expression and do the arithmetic.

  h = -16t^2 +129t

  h = -16(5^2) +129·5 = -400 +645 = 245

The height of the object after 5 seconds is 245 feet.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
