An ocean wave has a wavelength of 8 m and a frequency of 50 Hz. What is the wave speed? a.1600m/s
b.0.16 m/s
c.400 m/s
d.6.25 m/s

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

d no solution

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
