Answer:
B .... just took test and got a 100
Step-by-step explanation:
(N-2) * 180 so is 1800
(N-2) * 180 / 12 is 150
Answer:
Not enough info
Step-by-step explanation:
Find the length from the school to the community center (this is the shortest route).
2^2+7^2 = c^2
c = sqrt(53)
The amount of time the trip takes depends on how long it takes Miguel to walk one city block.
sqrt(53)*lengthOfTimeForOneCityBlockInMinutes = the minimum time.
Refer to the diagram shown below. It shows a vertical cross-section of the paraboloid through its axis of symmetry.
Let the vertex of the parabola be at the origin. Then its equation is of the form
y = bx²
Because the parabola passes through (18,8), therefore
8 = b(18²)
b = 0.02469
The parabola is y = 0.02469x².
The receiver should be placed at the focal point of the paraboloid for optimal reception.
The y-coordinate of the focus is
a = 1/(4b) = 1/0.098765 = 10.125 in
Answer: The receiver is located at 10.125 inches from the vertex.
