(.1mi/1min)
1.39mi/13.9 min
You have to multiply the bottom and the top by the same number to get the answer, you're trying to make the denominator 13.9 for the amount do minutes so you multiply the numerator by 13.9 to get the numerator
T=2π/|b|. The period of an equation of the form y = a sin bx is T=2π/|b|.
In mathematics the curve that graphically represents the sine function and also that function itself is called sinusoid or sinusoid. It is a curve that describes a repetitive and smooth oscillation. It can be represented as y(x) = a sin (ωx+φ) where a is the amplitude, ω is the angular velocity with ω=2πf, (ωx+φ) is the oscillation phase, and φ the initial phase.
The period T of the sin function is T=1/f, from the equation ω=2πf we can clear f and substitute in T=1/f.
f=ω/2π
Substituting in T=1/f:
T=1/ω/2π -------> T = 2π/ω
For the example y = a sin bx, we have that a is the amplitude, b is ω and the initial phase φ = 0. So, we have that the period T of the function a sin bx is:
T=2π/|b|
With assumptions about it being a *right* triangle and a and b being the legs, the answer is:
B) 35.5°
1/4x + 5/3x - 4 = 2 - 1/12x
Simplify.
Multiply 1/4x by 3/3, as well as multiplying 5/3x with 4/4.
1/4x × 3/3 = 3/12x
5/3x × 4/4 = 20/12x
So, our new question looks like this :
3/12x + 20/12x - 4 = 2 - 1/12x
Simplify.
23/12x - 4 = 2 - 1/12x
dd 4 to both sides, as well as adding 1/12x to both sides.
23/12x + 1/12x = 2 + 4
Simplify.
24/12x = 6
Simplify.
2x = 6
Divide both sides by 2.
x = 3
