The third one, 2 to the power of 5 over 6

√2  * 3√2

convert from radical form to exponent form to solve for the same root
( x^m/n = n√x^m )

2^(1/2) * 2^(1/3)  
2^{3/6} * 2^{2/6} - find common denominator (6)
6√(2^3) * 6√(2^2)  - convert back to radical form 
6√(2^3 * 2^2)- combine

6<span>√(</span>2^5)
then convert to exponential form again
~ 2^5/6 ~

Find the slope and the equation for the line passing through the points: (-3,0) and (-1,2)
dusya [7]

Answer:

  • slope: 1
  • equation: y = x +3

Step-by-step explanation:

The slope of the line between two points can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (2 -0)/(-1 -(-3)) = 2/2

  m = 1 . . . . . the slope of the line is 1

__

The value of the y-intercept can be found by solving the slope-intercept equation for b.

  y = mx +b

  b = y -mx

  b = (0) -(1)(-3) = 3 . . . . . using point (x, y) = (-3, 0)

The equation of the line with slope 1 and y-intercept 3 can be written as ...

  y = x +3

What is the equation of a circle with center (-4 2) and diameter 6?
ASHA 777 [7]

Use the general form:-

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre and r = radius

Here the radius = 1/2 * 6 = 3 so r^2 = 9 and we have the equation:-

(x + 4)^2 + (y - 2)^2 = 9 (answer)
