A (−3, 1) and B (3, 4) 2 Let A have coordinates (x1, y1). Let (x1, y1) = (−3, 1). 3 Let B have coordinates (x2, y2). Let (x2, y2) = (3, 4). 4 Find the length AB by applying the formula for the distance between two points. AB = "(x2 − x1)2 + (y2 − y1)2 = "[3 − (−3)]2 + (4 − 1)2 = "(6)2 + (3)2 = !36 + 9 = !45 = 3!5 = 6.71 1

Write cos 53 degrees in terms of sine.

SOVA2 [1]

Cos(x) = sin(90 - x)
cos(53) = sin(90 - 53)
cos(53) = sin(37)

I want to know the answers to the ones circled

Hello! I will do my best to help you understand and receive the answers.

Let's begin with our first question..

15.) Dao has 2 3/8 pounds of hamburger meat. He is making 1/4 pound burgers. How many burgers can he make?

For this problem we will have to use division. Our equation (use a calculator if needed) is 2 3/8 divided by 1/4 which equals 3.

Your final answer should be : Dao can make 3 hamburgers total.

I would answer the next question, but I believe from this information above you can try and figure it out. If you are still stuck, message me and i can help you from there.
