Answer:
116*
Step-by-step explanation:
36* + 28* = 64*
180* - 64* = 116*
For the first one is D
The second one is A
The third one should be B, it makes the most sence
Answer:
29
Step-by-step explanation:
7x + 1 + 4x - 3 = 42
11x - 2 = 42
11x = 44
x = 4
Substitute the value of X into the value for DE.
7(4) + 1 = 29
Answer:

Where k represent the number of wave
and
represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:

So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
Step-by-step explanation:
Since the sine function can be used to model light waves we can use the following general expression:

Where k represent the number of wave
and
represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:

So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
