Compound Interest -) Suntali deposited Rs 9,000 altogether in her saving account and fixed deposit
account in a bank. Saving account gives her 5% p. a. interest compounded annually
and fixed deposit account gives 10% p. a. interest compounded half-yearly. If she
got Rs 160 more interest from fixed deposit account at the end of one year, find how
much money did she deposit in her each account?

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

step-by-step explanation:

ask goog great chance of finding the solution there

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
