Density=mass/volume.
1) we have to calculate the iron volume in liters.
iron volume=second level - first level=49.10 ml-45.50 ml=3.6 ml
3.6 ml=3.6 ml(1 liter / 1000 ml)=0.0036 liters 

2) we calculate the mass iron in kg.
28.5 g=28.5 g(1 kg /1000 g)=0.0285 kg.
2) we calculate the density of iron.
density=0.0285 kg / 0.0036 liters=7.92 kg/L

7.92 kg/l=7.92 kg/L(1000 g/1Kg)(1000 cm³/1 L)=7.92 g/cm³.

answer: From this information the Iron density is 7.92 Kg/L or  7.92 g/cm³.

What is the a, b, and r for y=3.6(1.25)^x
tia_tia [17]

Answer:

a=3.6, v=1.25 and r=25%

Step-by-step explanation:

The given exponential function is

y = 3.6 {(1.25)}^{x}

We compare to the form:

y = a{(b)}^{x}

We have a=3.6, b=1.25

The r is the percentage of increase or decrease.

We realized there is a 25% increase because

y = 3.6 {(1 + 25\%)}^{x}

Hence

r = 25\%
