Use the Midpoint Rule with the given value of n to approximate the integral. Round the answer to four decimal places. 80 integral 0 sin( x ) dx, n = 4

-20.41

Step-by-step explanation:

We are given that:

n = 4

a = 0 rad

b = 80 rad

f(x) = sin (x)

The length of each sub interval is given by:

The ends of each sub interval is found by, starting at a = 0, and adding 20 rad. The sub intervals are:

(0, 20) (20, 40) (40, 60) (60, 80)

The midpoints of each sub interval are the average between the start and end point:

(10) (30) (50) (70).

According to the midpoint rule, with n =4.

The approximate integral is -20.41

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
