Find the distance between (-2, 8) and (11, 2). Round to the nearest hundredth.
andrew11 [14]

Answer: 14.32 units

Step-by-step explanation:

The formula for calculate the distance between two points is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

In this case, given the points (-2,8) and (11,2), we can identify that:

x_2=11\\x_1=-2\\\\y_2=2\\y_1=8

Therefore, we just need to substitute values into the formula in order to calculate the distance between the given points. This is (Rounded to the nearest hundred):

d=\sqrt{(11-(-2))^2+(2-8)^2}\\\\d=14.32\ units

If m and n are positive integers such that the greatest common factor of <img src="https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20n%5E
torisob [31]
The greatest common factor of m^{2}  n^{2} and m n^{3}

is
 
gcd(m*m*n*n, m*n*n*n) =m*n*n=m n^{2}

what we did, was to see how many m's and how many n's, each expression have, and then pick the smallest of each letter (factor).

the reason is that the common factor, must have enough m's and n's to divide the m's and n's of both expressions

so
45=m n^{2}
also 
45=5*9=5*3^{2}

thus, n is equal to 3
