Question

.
1. If sin 53 is close to 4/5 which is closest to the length of no
4cm
80cm
20cm
10cm

2/ A sine function can be used to model light waves. Green light has a wavelength of peridoe of about 510 nanometers (nm) which equation best models green light
y= sin pi/510 0
y = sin pi/255 0
y= sin 510/pi 0
y = sin 255/pi 0

Answer 1

2/ A sine function can be used to model light waves. Green light has a wavelength of peridoe of about 510 nanometers (nm) which equation best models green light
A. y= sin pi/510 0
B. y = sin pi/255 0
C. y= sin 510/pi 0
D. y = sin 255/pi 0

is the answer A, B, C, OR D

Answer 2

1. The closest length to sin 53 being 4/5 is 80cm.

2. The equation that best models green light is y = sin 2pi/510 x.

Answer 3

The answer is A, y = sin pi/510 x.
