What is the square root of 1,024

Shkiper50 [21]

1024 can be factored into
2(512) 
=2^2(256) 
=2^3(128) 
=2^4(64) 
=2^5(32) 
=2^6(16) 
=2^10 

Therefore, 
√1024 = √(2^10) = 2^5 = 32

Option C: -3 is the average rate of change between $x=-1$ and $x=1$

Explanation:

The formula to determine the average rate of change is given by

Average rate of change = $\frac{y_2-y_1}{x_2-x_1}$

We need to find the average rate of change between $x=-1$ and $x=1$

Thus, from the table, we have,

$x_1=-1$ , $y_1=5$

$x_2=1$ , $y_2=-1$

Thus, substituting these values in the formula, we get,

Average rate of change = $\frac{-1-5}{1+1}$

$=\frac{-6}{2}$

$=-3$

Thus, the average rate of change between $x=-1$ and $x=1$ is -3.

Hence, Option C is the correct answer.

A circle has its center at the origin, and (5, -12) is a point on the circle. How long is the radius of the circle?

aivan3 [116]

Hello here is a solution :
 the radius of the circle is OA A(5;-12) and O (0;0)
OA= square root ((5-0)² + (-12-0)²)
 = square root (25+144)
 = square root(169)
 OA = 13
