You throw a ball at a height of 5 feet above the ground. The height h (in feet) of the ball after t seconds can be modeled by the equation h= -16t^2 +44t +5

a. After how many seconds does the ball reach a height of 15 feet?
b. After how many seconds does the ball hit the ground? Round your answer
to two decimal places.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
