Chuck stone is standing on top a higher platform. He fires a rock up into the air with his slingshot. Well it is in flight, the rocks distance above the ground is a quadratic function of time. At times one, two, and three seconds after he fired it, the rock is 68, 96, and 114 m above the ground, respectively. This shows that the graph of the quadratic function includes the points: (1,68) (2,96) (3,114) a.) write the particular equation from the rocks distance above ground (d) as a function of time (t).

b.) What is the highest the rock will be above ground?

c.) how high is the platform? (The rock is at the platform level when t = 0.)

i dont know sorry

step-by-step explanation:

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

what is the answer?
