Answer:
e. 5.0329 g/mL
Step-by-step explanation:
Density is defined as mass divided by volume of an object. The volume displaced is:
#Density is then calculated as:
#Correct significant figures should correspond to the highest given in the question.
Hence the density of the metal is 5.0329g/mL
Answer:
No, the student is incorrect.
Step-by-step explanation:
First we need to find the x-intercept. You can do so by solving for the variable x, and letting y = 0.
The x-intercept of the graph of is at
, because the formula for a point on a graph is
, where the x-value comes first.
The x-value is 5, and the y-value is 0, because that is what we substituted into the equation.
In other words, when the graph touches the x-axis at 5 (5, 0), the y-value of this point of intersection will be 0.
This student is NOT correct because the point they give (0, 5) is flipped from the correct x-intercept.
