The correct answer to the first question would be the statement 'A protractor and ruler are used to take accurate measurements'. The protractor and the ruler can be used to construct polygons and parallel lines interchangeably.
The correct answer to the second question would be 'open the compass to the width of the line and draw two arcs'.
Given that the rate of change of y with respect to x is inversely proportional to y². Its equation can be written as :-
where 'k' is the proportionality constant, it can take any real value.
We can solve it by integrating the above equation with respect to x.
Rewriting and rearranging the terms of above equation :-
y²·dy = k·dx
Integrating both sides :-
∫ y²·dy = ∫ k·dx
= k·x
y³ = 3·k·x + C
where C is the constant of integration.
So, y³ = 3·k·x + C is the final answer.
first, we can distribute the negative into the numbers in parentheses
9x-(4x-1)=2
9x-4x+1=2
now we can combine like terms and then isolate x
5x + 1 = 2
5x = 1
x = 1/5
hope this helps

<span>
</span>
Where
l=lenght,
w=width
h=height
So, as this prism has a length of 312 inches, a width of 5 inches, and a height of 112 inches, the volume is calculated as follows:
