Answer:
the maximum height of the ball is 81.125 feet above the ground. when the ball is at its peak, the ball is 156.25 feet away from home plate.
Step-by-step explanation:
x = d
y = h
to find the x coordinate of the vertex of a parabola, use the equation
x = -b/2a
y = ax^2 + bx+ c
y = – 0.0032x^2 + x + 3
x = -1 / 2 • - 0.0032
x = 156.25
plug x into original equation to find the the y coordinate of the vertex
y = – 0.0032 • (156.25)^2 + (156.25) + 3
y = – 0.0032 • 24414.0625 + 159.25
y = – 78.125 + 159.25
y = 81.125
Answer: $17.92/sandwich
Step-by-step explanation:
Let S be the price of a sandwich ($/sandwich).
7S is the total cost of the sandwiches. Add a drink for $2.50 to find the total cost, which we are told comes to $140.50
7S + $2.50 = $140.50
7S = $138
S = $19.7143
It is odd that this includes a fraction of a single penny (0.43 cents). Something is incorrect in the data given, since this should equal a whole number. For now, I'll round up to $19.72. The additional 7*($0.0043) = 4 cents will be treated as a tip.
