A right hand Riemann sum has been calculated for an increasing function between x=1 and x=2, using n=100.the value for the right hand sum is found to be 3.34 units. Which could be the actual area under the curve.

(B) 3.33

Step-by-step explanation:

The picture below shows a right-sum estimation for an increasing function. As you can see, the right-sum will overestimate the value of the actual area; therefore, the actual area must be slightly lower than the estimated value.

If the estimated value is 3.34, then slightly lower than that is 3.33.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
