Answer:
To find the maximum of a function in ax^2 + bx + c form, you can use the formula: maximum = c - (b^2 / 4a).
In this question, a = -16, b = 180, and c = 63.
Maximum = 63 - (180^2/4(-16))
Maximum = 569.25
Finally, rounding this to the nearest tenth of a foot, the final answer is 569.3 ft.

Answer:
Area required for circular hot tube = 6,218 inch² (Approx.)
Step-by-step explanation:
Given:
Diameter of circular hot tube = 89 inches
Value of π = 3.14
Find:
Area required for circular hot tube
Computation:
Radius of hot tube = Diameter / 2
Radius of hot tube = 89 / 2 inches
Area required for circular hot tube = Area of circle
Area of circle = πr²
Area required for circular hot tube = πr²
Area required for circular hot tube = (3.14)(89/2)²
Area required for circular hot tube = (3.14)(7921 / 4)
Area required for circular hot tube = (3.14)(1,980.25)
Area required for circular hot tube = 6,217.985
Area required for circular hot tube = 6,218 inch² (Approx.)
Answer:
38
Step-by-step explanation:
v=u+at
v=16+11(2) Do multiplication first
v=16+22
