Given h(x)=-x-1,find h(-2)
1 answer:
Given that : h(x) = - x - 1 .
And we are required to find the value of h(-2) .
For this just in place of x replace it by -2 .
So ,
=> h(x) = - x - 1.
=> h(x) = - ( x + 1 ) .
=> h(-2) = - ( -2 + 1 )
=> h(-2) = - 1 × -1 .
=> h(-2) = 1

Answer:
The compound interest is Rs8275
Step-by-step explanation:
The rule of the compound interest is A = P, where
- A is the new amount
- P is the initial amount
- r is the interest rate in decimal
- n is the number of periods
- t is the time
The interest I = A - P
∵ The amount of investment is Rs25000 for 3 years
∴ P = 25000
∴ t = 3
∵ The rate of interest is 10% per annum, compounded annually
∴ r = 10% = 10 ÷ 100 = 0.1
∴ n = 1 ⇒ compounded annually
→ Substitute these value in the 1st rule above to find the new amount
∵ A = 25000
∴ A = 25000
∴ A = Rs33275
→ Use the 2nd rule above to find the interest
∵ I = 33275 - 25000
∴ I = 8275
∴ The compound interest is Rs8275
