Find the sum which amounts to Rs 9261 at 10% per annum compound interest for 18 months ,interest payable half yearly
, where A is amount , r is rate =10% = 0.10 , n is intervals of compounding n=2 , t is time = 18 months=1.5 years
Lets plug in



divide both sides by 1.006012008

The given function is,
.
Or, 
To find the inverse of a function, first step is to switch x and y. Therefore,

Next stpe is to solve the above equation for y t get the inverse f f(x). Hence, multiply each sides by y + 5 to get rid of fraction form. So,

xy + 5x = 2y - 1
xy = 2y - 1 - 5x Subtract 5x from each sides to isolate y.
xy - 2y = -5x - 1 Subtract 2y from each sides.
y(x - 2) = -5x -1 Take out the common factor y.
Divide each sides by x-2.

So, 
Now when we will compare
with
then we will get a = -5, b = -1, c = 1 and d=-2
So, 
Hope this helps you!
Answer:
9.7%
Step-by-step explanation:
6x+7y=32 and 2x+5y=16
if you add the two equations you get the first answer and if you subtract the two equations you get the second answer
Answer: B
Step-by-step explanation:
the parabola having (1,5) as vertex have as equation:
y=k*(x-1)²+5
It is passing through (2,8)
8=k*(2-1)²+5 ==> k+5=8 ==> k=3
equation is y=3(x-1)²+5
Answer B
