Explain​ how, in​ general, riemann sum approximations to the area of a region under a curve change as the number of subintervals
Lyrx [107]

As you increase the subintervals the area will be closer and closer to the real value. In other words your approximation gets better.

As you increase the intervals, there will be more rectanagles and the added area of these rectangles are converging towards the actual area under the curve.

In parallelogram WXYZ, what is CY?<br> 11 ft<br> 15 ft<br> 21 ft<br> 23 ft
erastovalidia [21]

Answer:

15 ft

Step-by-step explanation:

In a parallelogram the diagonals bisects each other

So WC= CY

x+4=2x-7 solve the equation for x

Subtract x from both sides

x-x+4=2x-x-7

4=x-7

Now we add 7 on both sides

4+7=x-7+7

x=11

Now we need to find CY

CY= 2x-7

Plug in 11 for x

CY= 2(11)-7=22-7= 15
