A. Find the exact value: ∫2π0sin(θ)dθ=
B. Find the MID(1) and MID(2) estimates for the integral: MID(1) = MID(2) =
C. Sketch MID(1) and MID(2) for this integral. Be sure that you can explain, using your sketch(es) why your results in A and B are related as they are. What would you get if you found MID(3)?
How about MID(n)?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

m∠a is 90°

m∠b is 40°

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
