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.
Good question let me see if I can figure it out
Answer:
3pi is irrational.
Step-by-step explanation:
An irrational number multiplied by a rational number is always irrational.
:)
-5x - 15 > 10 + 20x...subtract 10 from both sides, add 5x to both sides
-10 - 15 > 20x + 5x ...simplify
-25 > 25x...divide both sides by 25
-25/25 > x ....reduce
-1 > x or x < -1 <===
Hey there!:)
b1+b2
--------- x h =area
2
(3+5)/2h=area
8/2h=area
4(2)=area
area= 8ft squared (this is your answer)
Hope this helps! Let me know if you need more help:)
