ANSWER

80  {ms}^{ - 1}

EXPLANATION

The average velocity of the ball is the rateof displacement over the total time.

The height of the ball, in feet, after t seconds is given by the function:

f(t)=-16t^2+192t

At time t=1, the height of the ball is

f(1)=-16(1)^2+192(1)

f(1)=-16+192 = 176ft

At time t=6, the height of the ball is

f(6)=-16(6)^2+192(6)

f(6)=-16(36)+192(6)

f(6)=-576+1152 = 576

The average velocity

=  \frac{f(6) - f(1)}{6 - 1}

=  \frac{576- 176}{6 - 1}

=  \frac{400}{5}

= 80  {ms}^{ - 1}

) Kora is working on a scrapbooking project. She buys packages of stickers at two different stores.
Rus_ich [418]

The expression that can be used to represent the total price is 3(p - $0.75) + 5(p - $1).

The expression that can be used to determine the total amount spent in store A is:

  • number of stickers bought x ( price of the item - discount)
  • number of  stickers bought = 5
  • price of the stickers  = p
  • discount = $1

5(p - $1)

The expression that can be used to determine the total amount spent in store B is:

  • number of stickers bought x ( price of the item - discount)
  • number of  stickers bought = 3
  • price of the stickers  = p
  • discount = $0.75

3(p - $0.75)

Total price = 3(p - $0.75) + 5(p - $1)
