18 is the answer because... Woodwinds have 6, Percussion has 3, and Brass has 9! Hope that I helped! :)
Answer:
Step-by-step explanation:
The vertex form of a quadratic function is f(x) = a(x – h)2 + k, where a, h, and k are constants. of the parabola is at (h, k).
Answer:
48√3 cm
Step-by-step explanation:
I'm assuming that ∠A = 30°, ∠R = 60°, and ∠Y = 90°.
The sides of a 30-60-90 triangle are in the ratio 1:√3:2.
RY is opposite the 30° angle and has length 48 cm.
AY is opposite the 60° angle, so the length of AY = 48√3 cm.
I did this on a calcalator 3÷5=0.6
You can calculate the difference/vector of both points:

then calculate the magnitude/length like pythagoras
