Cos(t/2) I got .45 is that what you were looking for or do I need to plug it into the equation up top? can you give me notes of something? cos( -9/11/2) = .45
Answer:
8
Step-by-step explanation:
You use law of sines, and get: AB/sin(53) = 7/sin(44)
You multiply both sides by sin(53), and get:
AB = 7*sin(53)/sin(44)
That means AB is 8.04776679886, which rounds to 8
Answer:

Step-by-step explanation:
.
m is the slope of the line. To find it we can do
which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So:
. Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant
.

- Re-arranging to get b
Now re-write the equation as we have the constants.

That's easy it is 5,300,000 I think by the way Might be wrong I hurt my eye so yea don't say I am not good at math it is my eye hurting or it can be 5,300,288
