Therefore, beats per minute did increase for 36.
Step-by-step explanation:
48: 2/3=x:1
48=2/3 × x
x=3/2×48
x=72
81:3/4=x:1
81=x×3/4
x=4/3×81
x=108

Answer:
F(v)=0
Step-by-step explanation:
F(v) = [3x*2y, 5xx, 9yy]
Calculate the product
F(v) = [3x*2y, 5x*x, 9y*y]
The derivative of a constant is always 0
F(v) =((6xy,5,9))
f(v)=0
