Estimate the area between the graph of the function f and the interval [a, b]. Use an approximation scheme with n rectangles similar to our treatment of f(x) = x2 in this section. If your calculating utility will perform automatic summations, estimate the specified area using n = 10, 50, and 100 rect-angles. Otherwise, estimate this area using n = 2, 5, and 10 rectangles. 1. f(x) = x^(.5); [a, b] = [0, 1].

I will give brainliest to anyone whoever answers this first with a legit answer.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

17.08

correct me if i am wrong.

add a pic of the graph, then ill edit this "answer" and solve it for you : 3
