This is your generic run-of-the-mill sinusoidal function:
f(x) = sin(x)
This is the same sine function but with a phase shift of 3 units to the right:
f(x) = sin(x-3)
This is the sine function but with an amplitude of 4 units:
f(x) = 4sin(x)
This is the sine function but flipped across the x-axis:
f(x) = -sin(x)
Combine all these transformations to get:
f(x) = -4sin(x-3)
Okay so we're trying to figure out what m is in this problem, so let's single it out by dividing both sides by -2/3
then m=18
Answer:
Step-by-step explanation:
I think you mean tan^2θ, not tan2θ.
Use the trigonometric identities
secθ = 1/cosθ
cscθ = 1/sinθ
tanθ = sinθ/cosθ
sin²θ = 1-cos²θ
cos²θ = 1-sin²θ
340% is 3.4. So this year he made 3.4*620+620=4.4*620=$2728.
By similar triangles...
p/37=33/83
p=37(33)/83
p=1221/83 m
p≈14.711 m (to nearest thousandth of a meter, or nearest millimeter)
