Answer:
8y
Step-by-step explanation:
Product means multiply
8*y
8y
Answer:
Step-by-step explanation:
hello :
y+2=x²−2siny
calculate y' : y' = 2x -2y'cosy
when x= 2 and y=0 ( at the point(2,0)
) y' is the slope :
y' = 2(2)-2y'cos0 but cos0 =1
y' = 4 -2y'
3y' =4
so : y' = 4/3
Answer:
10.153 years
Step-by-step explanation:
The future value of such an investment is given by ...
FV = P·(1 +r/12)^(12t)
where P is the principal invested, FV is the future value of it, r is the annual interest rate, and t is the number of years.
Dividing by P and taking the log, we have ...
FV/P = (1 +r/12)^(12t)
log(FV/P) = 12t·log(1 +r/12)
Dividing by the coefficient of t gives ...
t = log(FV/P)/log(1 +r/12)/12 = log(3000/2000)/log(1 +.003333...)/12 ≈ 121.842/12
t ≈ 10.153 . . . years
I am currently taking Geometry right now, so I understand where you are coming from. I think it's just a matter of approaching it differently. My teacher always says she is trying to get us to think, not memorize. If you think a tutor would help you, then go for it! Just make sure you are learning the material not just for the grade, but so that you actually understand it. That's the most important part. Good luck!
