James has mapped his seat and his teacher's seat on the coordinate plane at (0,10) and (–4,6). Find the distance between their s
pshichka [43]

Answer:

4√2 units (Answer C).

Step-by-step explanation:

Going from the seat at (-4,6) to the one at (0,10), x increases by 4 units and y increases by 4 units.  We need to use the distance formula to determine how far apart these seats are.

d = √(change in x)^2 + (change in y)^2 ).

That works out to:

d = √(4^2 + 4^2) = √(32) = 4√2 units (Answer C).

Juliette [100K]

Answer:

\large\boxed{x^\frac{4}{5}}

Step-by-step explanation:

\sqrt[n]{a}=a^\frac{1}{n}\Rightarrow\sqrt[5]{x}=x^\frac{1}{5}\\\\\sqrt[5]{x}\cdot\sqrt[5]{x}\cdot\sqrt[5]{x}\cdot\sqrt[5]{x}=x^\frac{1}{5}\cdot x^\frac{1}{5}\cdot x^\frac{1}{5}\cdot x^\frac{1}{5}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=x^{\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}}=x^\frac{4}{5}

PolarNik [594]
No.
EXPLANATION:
To tackled this problem we should find an equivalent denominator.

We find that the lcm ( lowest common denominator ) is 20.

1 x 5 = 5
4 x 5 = 20

2 x 4 = 8
5 x 4 = 20.

so the answer is no.

Using the digits 0 to 9, at most one time each, fill in the boxes to create a square, with one of the vertices at (2,3). Hint: 2
coldgirl [10]

Answer:

See explanation

Step-by-step explanation:

One vertex is at point (2,3).

Go 1 unit to the left and 5 units up, then the second vertex will be at the point (1,8).

Go 5 units to the right and 1 unit up, then the third vertex will be at point (6,9).

Go 1 unit to the right and 5 units down, then the fourth vertex will be at point (7,4).

Go 5 units to the left and 1 unit down to get into the vertex (2,3).

Since you always move one unit in one direction and 5 units in another direction, obtained quadrilateral will be a square.

See attached diagram for details.
