Answer:
The density would be 2.89 g/ml
Step-by-step explanation:
To find this, we first need to find the mass of the rock. we can do this by subtracting the weight of the water and cylinder from the weight after the rock is added.
250g - 120g = 130g
Now we need to find the volume. To get this, we subtract the volume of the water before and after the rock is added.
75ml - 30ml - 45ml
Now we use the density formula and solve
D = m/v
D = 130g/45ml
D = 2.89 g/ml
Answer:
Option A
Step-by-step explanation:
Domain of a function is a set of x-values (input values).
Range of a function is a set of y-values (output values).
Since, input and output values of the function given in the graph vary from negative infinity to positive infinity
Domain of the function given in the graph will be,
(-∞, ∞)
And range of the function is,
(-∞, ∞)
Option (A) will be the correct option.
