Applications of quadratic equations
a ball is thrown vertically upward. after t seconds, its height h (in feet) is given by the function
h = -16t^2+ 96t+6.
a. what is the height from which the ball is thrown (the initial height)?
b. how long does it take for the ball to reach its highest point?
c. what is the maximum height that the ball will go?
d. when will the ball hit the ground?
e. at what times will the ball reach 86 feet?

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
