Answer:
A. 3.85 units
Step-by-step explanation:
Diameter = 2 × radius
radius = 7.7 /2
= 3.85 units
The equation of this parabola will have the form f(x) = a(x+5)(x-4), which works out to f(x) = a(x^2 + x - 20). Since the parabola passes thru (3,40),
40 = a(3^2 + 3 - 20), or 40 = a(-8), so a = -5.
Thus, the equation of this parabola is y = -5(x^2 + x - 20).
666/2= 333 Divide in half.
333 + 84 = 417 Add 84 to bench since its $84 more.
666 - 417 = 249 Subtract to get value of table.
Therefore, the table costs $249 and the bench costs $417.
X=21/2
X=10.5
X=10 1/2
There all right
