Solve on the interval [0,2pi)
1+ sin 0=1/2

sin(theta) = 7pi/6, 11pi/6

Step-by-step explanation:

Start by replacing theta with x (they are the same thing in this case.

Next Solve...

  1 + sin(x) = 1/2

  sin(x) = -1/2 (subtract one from both sides)

Plug in y = sin(x) on a graphing calculator

Plug in y = -1/2

See where the points intersect between 0 and 2pi

They should intersect at 7pi/6 and 11pi/6

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
