<span>The sinusoidal curves are shown in the picture attached.
Note that the two waves have the same amplitude (same "height"), the same wavelength (same distance from one peak to the next one) and therefore the same frequency, but different phase (they start in different points).
When you sum two different sinusoidal curves with the same amplitude and frequency, but different phase you get a sinusoidal wave with the same frequency as the original curves, but a different amplitude and a different phase.
Therefore, the correct answer is
graph B).

Answer:
D
Step-by-step explanation:
the ratio of rows to flowers is 1:4, so for every 1 row, there are 4 flowers. so the equation would be f = 4r. do you understand how I got to that?
Answer:
I think it is infinate and 1 solution
Step-by-step explanation:
Answer: Inequality
Step-by-step explanation:
From the question, if we can describe 15×-10 as an expression, then we would describe 6×-2< 35 as an inequality. An
inequality is used to compare two values, and shows if one is less than, or greater than, or maybe not equal to the other value.
For example, a ≠ b means that a is not equal to b and a < b means a is less than b while a > b means a is greater than b. From the question, 6×-2< 35 means that 6x - 2 is less than 35.
