Mass = density* volume
since density= mass/volume then mass/volume*volume=mass
= 4.5*0.4 = 1.80g
Answer:
Up
Step-by-step explanation:
Here the easy rules to remember the orientation of the parabolas are
a) If x is squared it opens up or down. And its coefficient of {![x^{2}[tex] is negative it opens down.b) If y is squared it opens side ways right or left. It its coefficient of [tex]y^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%5Btex%5D%20is%20negative%20it%20opens%20down.%3C%2Fp%3E%3Cp%3Eb%29%20If%20y%20is%20squared%20it%20opens%20side%20ways%20right%20or%20left.%20It%20its%20coefficient%20of%20%5Btex%5Dy%5E%7B2%7D)
Hence in our equation of parabola

x is squared and its coefficient is positive , hence it opens up towards positive y axis.
First solve the 2 inequalities for x:-
x > 0 or x <= -5
The last choice is the correct one.
