Tanya kicks a ball into the air. The function that models this scenario is f(t) = –16t2 + 96t, where h is the height of the ball
2 answers:
Answer:
the ball hit the ground at
Step-by-step explanation:
we have
This is the equation of a vertical parabola open downward
The vertex is a maximum
we know that
The x-intercept of the function is the value of t when the value of h(t) is equal to zero
The ball hit the ground when h(t) is equal to zero
equate the function to zero and solve for t
Factor the leading coefficient
The solutions are
therefore
the ball hit the ground at

To find the better buy divide 4.50 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0. 80 per pound.
The cost price per pound is the amount of money required to buy one pound of a brand or goods.
To find the cost price per pound, divide the total amount of cost of the goods to the total number of goods.
At one farmer’s market, bananas cost $0.80 per pound.
At another farmer’s market, bananas are sold in 5-pound bags for $4. 50 per bag. To compare it with first market price, divide the 5 pound bags with $4.50.
The cost of one bag in this market is,
As this cost is less, thus, the cost of this market for one banana is less than the first market and so this is the better buy.
Hence, to find the better buy divide 4.50 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0. 80 per pound.
