Answer:
B, 
Step-by-step explanation:
Using the law of cosines, which is 
, you can simply insert all the values.
c=|u+v|
a= r value of u (10)
b= r value of v (5)
To find C, you simply have to subtract v from u, and then subtract that number from 180 to find the reference angle.
I.E.: ∠135 - ∠30 = ∠105 ↔ 180 - 105 = 75 = C
so, the completed equation would be 10^{2} + 5^{2}- 2(10)(5)cos(75)

oouu I'm in 7th grade science and I already did this I can help!
Initial investment was when x=0, when no change had occured
c(0)=7(0)^2-6(0)+5
c(0)=5
this is in thousands
5*1000=5000
answer is $5000 is initial
