Find the side length of a cube with a volume of 422 yd ^3

Mathematics
1 answer:
Dmitry_Shevchenko [17]3 years ago
6 0

Answer:

5.5 yd

Step-by-step explanation:

To find the side length of the cube, the volume is a clue. We know that all sides of a square are equal, and the volume of a cube is length×width×height. Since the length, width and height are all the same, we know it is V=x³. Since we know the volume, we can plug in and solve for x.

166=x³

In order to get x alone, we have to cube root both sides.

x≈5.5 yd

On a coordinate plane, what is the distance between (-7, 3) and (2,3)?
Angelina_Jolie [31]

Answer:

The distance is 9

Step-by-step explanation:

Distance formula: \sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2   }

Plug in the points:

\sqrt{(2-(-7))^{2}+(3-3)^2   } = \sqrt{(9)^{2}+(0)^2   } = \sqrt{(9)^2} = 9

What's the 13th term in the arithmetic sequence
leva [86]
Replace n with 13 and simplify

an = 84+(n-1)*(-6)
a13 = 84+(13-1)*(-6)
a13 = 84+(12)*(-6)
a13 = 84+(-72)
a13 = 84-72
a13 = 12

The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains
aniked [119]

Answer:

\[y=-2x+13\]

Step-by-step explanation:

Equation of the line CD is given as \[y=-2x-2\]

Slope of the line CD = -2

Slope of the line parallel to CD = -2

Equation of the line parallel to CD is given by \[y=mx+c\]

\[y=-2x+c\]

But this line passes through (4,5)

Substituting the values in the equation:

\[5=-2*(4)+c\]

=> \[c=5+8=13\]

So the overall equation of the parallel line is given by \[y=-2x+13\]
