Answer 1

Do the following. a = 100 (a) By reading values from the given graph of f, use five rectangles to find a lower estimate and an upper estimate for the area under the given graph of f from x = 0 to x = 200. A (lower estimate) A (upper estimate) (b) Find new estimates using ten rectangles in each case. A (lower estimate) A (upper estimate)

Answer 2

ok if a = 100, then the tick marks are increasing by

Answer 3

20

Answer 4

since you want 5 rectangles, that means we need ( 200 - 0) / 5 = 40 will be your base for the rectangle

Answer 5

since you want 5 rectangles, that means we need ( 200 - 0) / 5 = 40 will be your base for each rectangle

Answer 6

let's write out the points on this curve

Answer 7

(0, 20 )
(40,60)
(80,not sure
(120,
(160,
(200,
