Answer:
50 divided by 3/4 =
Step-by-step explanation:
he spent 37 dollars and 5 cents
Given:
Rectangular coordinate = (8, 6)
To convert:
Rectangular coordinate to polar coordinate with r > 0 and 0 ≤ θ < 2π.
Solution:
Let us find r:
r = 10
Now, find θ:
Cancel the common factor 2.
θ = 36.87°
The polar coordinates are (r, θ) = (10, 36.87°).

wavelength = wavespeed / frequency
wavespeed = 16/8 = 2
Question 5
(400/60s) = 6.6667 waves/ sec (Hz).
<span>Velocity = 0.008m/sec. </span>
<span>Wavelength = (v/f) = 0.008/6.6667 = 0.0012 metre (1.2mm).
