Density=mass/volume
given mass=120g and volume=200cm3
density=
or abot 0.6
the density is
Just plug x in and you'll get each y value.
So the answer is A.
Answer:y=-1/4x-2
Step-by-step explanation:
40 feet = 8 foot shadow
So in order to go from 40 to 8 you divide by 5.
So if you have a person who casts a 2 foot shadow, you have to multiply by 5.
Your answer would be 10 feet.
Hope I helped :)
So hmm notice the picture below
thus, the perimeter of the gutter is just w + w + l, or 2w +l
thus
take the derivative of A(w), zero it out, check any critical points in the interval of (0, 22), for a maxima
recall, the aluminum sheet is just 22inches long, thus, whatever the "depth" or "w" is, has to be more than 0, and less than 22
