we know that
The volume of a cube is equal to
where
s is the length side of the cube
In this problem we have
The volume is equal to
therefore
the answer is the option B
A cube with side lengths of 3 feet has a volume of 27 cubic feet
The slope of a line that is perpendicular to a line whose equation is −2y = 3x + 7 is
Solution:
Given that we have to find the slope of the line that is perpendicular to a line whose equation is −2y = 3x + 7
The slope intercept form is given as:
y = mx + c
Where "m" is the slope of line and "c" is the y - intercept
Given equation is:
On comparing the above equation with slope intercept form,
We know that product of slope of a line and slope of line perpendicular to it is -1
Therefore,
Thus slope of line that is perpendicular to given line is
