Question

Evaluate  r left parenthesis x right parenthesis equals fraction numerator square root of 2 x end root over denominator 7 end fraction for the variable x = 5 to the nearest hundredth.

  1. 0.35
  2. 0.45
  3. 0.55
  4. 3.16

hintHint:

Substitute the given value of x in r left parenthesis x right parenthesis equals fraction numerator square root of 2 x end root over denominator 7 end fraction and round it off to nearest hundredth

The correct answer is: 0.45


    Given , r left parenthesis x right parenthesis equals fraction numerator square root of 2 x end root over denominator 7 end fraction and x = 5
    r left parenthesis 5 right parenthesis equals fraction numerator square root of 2 cross times 5 end root over denominator 7 end fraction equals fraction numerator square root of 10 over denominator 7 end fraction almost equal to fraction numerator 3.16 over denominator 7 end fraction almost equal to 0.45

    Find the x-intercept and y-intercept of y equals square root of x minus 2.

    Here we used the concept of intercepts. The points on a graph where the graph crosses the two axes are known as the intercepts (x-axis and y-axis). The x-coordinate is the location where the graph crosses the x-axis, and the y-coordinate is the location where the graph crosses the y-axis. So the intercepts are x-intercept = 4; y-intercept = -2
