An irregular solid with a mass of 45.0 g was dropped into and sank to the bottom of a graduated cylinder containing water. The i
Law Incorporation [45]
The answer is 2.25g/ml or 2.25 g/cm³

To do this, you need to know the formula of density. Density is the mass per unit of volume. 

D= \frac{M}{V}

Where:
D = Density
M = Mass
V = Volume

You already have your mass, which is 45.0g, so what is your volume?

A graduated cylinder measures the volume of liquids. The procedure that was done here is called the displacement method. You can get an estimated volume of an irregular object by subtracting the initial volume from the final volume. 

In this case, it would be:

<span>70.0mL - 50.0mL = 20.0 mL
</span>

The volume is then 20.0mL. 

Now that we have the volume we can solve for density. 

D= \frac{45.0g}{20.0mL}

D= 2.25\frac{g}{mL}

Now take note that 1mL = 1cm³. So you can also express the answer as

2.25g/cm³.

Rewrite f(x)=x2+8x-20 in the form that would most easily help you identfiy the zeros of the function
den301095 [7]

Answer:

f(x) = (x+ 10)(x - 2)

Step-by-step explanation:

We want to rewrite

f(x) =  {x}^{2}  + 8x - 20

in the form that would most easily help you identfiy the zeros of the function.

This the same as writing in factored form.

f(x) =  {x}^{2}  + 10x - 2x - 20

Factor by grouping:

f(x) =  {x}(x+ 10)- 2(x  + 10)

Factor further to get:

f(x) = (x+ 10)(x - 2)
