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

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
