1. An object submerged in water, rises up a volume of water equal to the volume of the object.
2. 1 milliliter of water has a volume of 1 cubic centimeters.
3. Mass= Density * Volume
-----------------------------------------------------------------------------------------------------
The water level rises from 20.mL to 41.mL means that a volume of 21mL of water has been displaced.
This means that the volume of the object is 21 cm cubed. (by 1 and 2)
By 3, the density of the piece of metal is:
Density=Mass/Volume=140 g / 21 cm^3= (140/21) g/cm^3=6.67 g/cm^3
Answer: 6.67 g/cm^3
Answer: c = 1.25p
----
You're told that peppers cost $1.25 per pound. That means for each pound of pepper, you would have to add another $1.25 in order to find the total cost.
Another way of saying that is by multiplying $1.25 by the number of pounds, which is represented by p. That means cost, c, equals 1.25p. Or c = 1.25p.
1) |x| is the absolute value function. Its vertex is at (0,0).
2) |x-1| has the same graph as does y = |x|, except that the vertex is shifted 1 unit to the left.
3) -3|x-1| has the same graph as the previous result, except that we must reflect the previous graph in the x-axis.
4) Replace the solid lines you used in this graph with dashed ones.
5) Shade the area beneath y = -3|x-1|
In summary:
the desired graph is the shaded area below the inverted v-shaped graph of
y = -3|x-1|. Its vertex is at (-1,0).
Answer:
The lines intersect at (-2,2).
Step-by-step explanation:
The line has an y intercept of 1 and a slope of -1/2 so after graphing the both of them thats where they intersect.
