Answer:
b, c, d
Step-by-step explanation:
y=kx+b
or
y=kx
so y=5,25x-right
y=0,5x-right
y=2,5x+7-right
Answer:
A
Step-by-step explanation:
The rectangle has an area of 30ft^2
Each triangle has an area of 25ft^2
25+25+30=80
The answer 16. Because it is 4 cheeses to the power of 2.
Answer:
Yes, because when waves are at the same place at the same time, the amplitudes of the waves simply add together and this is really all we need to know!
Step-by-step explanation:
The sum of two waves can be less than either wave, alone, and can even be zero. This is called destructive interference.
If we place the waves side-by-side, point them in the same direction and play the same frequency, we will have constructive interference.
