List x1, x2, x3, x4 where xi is the midpoint endpoint of the five equal intervals used to estimate the area under the curve of f(x) between x = 0 and x = 10.

1, 3, 5, 7, 9

Step-by-step explanation:

Left point: a=x=0

Right point: b=x=10

Range: r=b-a→r=10-0→r=10

Width of each of the five equal intervals: w=r/5→w=10/5→w=2

The first midpoint is x1=a+w/2→x1=0+2/2→x1=0+1→x1=1

The second midpoint is x2=x1+w→x2=1+2→x2=3

The third midpoint is x3=x2+w→x3=3+2→x3=5

The fourth midpoint is x4=x3+w→x4=5+2→x4=7

The fifth midpoind is x5=x4+w→x5=7+2→x5=9

50x5=$250

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137
