The answer is one.
( 18 x 2) + (18 x 3) = 36 + 54
After 12 years the investment will be worth $5145.
The formula used for compounded interest is:
A = P(1+r/n)^nt
A = future value
P = Principal Amount
r = interest rate
n = no of times interest is compounded
t = time
In the question given:
P = $2100
r = 7.75% or 0.0775
n = 1
A= 2100 *(1+0.0775)^12
A= 2100 *(1.0775)^12
A= 2100 * 2.45
So, after 12 years the investment will be worth $5145.
9 can be represented as 9/1, which is the reciprocal of 1/9.
The quadratic function is given as:
The standard form of a quadratic function is given as:
, where, 'a', 'h' and 'k' are real numbers.
Now, in order to convert the given function to standard form, we use completing by square method.
Now, can be rewritten as:
Therefore, the standard form of the function is:
