If a sample of 18 metal marbles has a total volume of 21.0 ml and a total mass of 20.7 grams, what is the density of the metal marbles?

.98

Step-by-step explanation:

The density of any object is calculated by the formula:

Density=

In this case the Mass is 20.7 grams, and the volume is 21 ml, what you have to do now is just put the values in the formula and do the division:

D=

The division will be equal to:

D== .98

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
