Your Principal, P, is $400. Your interest rate, expressed as a decimal, is 0.03. Here, n is 1, since there is just 1 compounding period per year.
How much would you have after 16 years under such circumstances?
A = Amount = $400(1+0.03)^16. => $400 (1.03)^16 = $400(1.60)
Thus, you would have accumulated $641.88 after 16 years. Sounds like a pretty good deal to me. ;)
The answer is 10.4 because you multiply 0.2 by 52
Step-by-step explanation:Step-by-step explanation:
For Sienna to be able to take the square root of both sides while solving a quadratic equation, she must have an expression with square on at least, the side that contains the variable she is trying to determine. Equation of the form:
(x + a) ² = b
'a' and 'b' could be any number, -1, 0, 1/3, -5/6, anything really.
So, she can take square roots of both sides then, like this
√(x + a)² = √b
x + a = ±√b
x = -a ± √b
Square roots always cancel out squares, and the '±' is because a square is satisfies by both + and -, 3² = 9, and (-3)² = 9.
It is the nature of the problem being solved that determines if we take just one or both of these answers.
Answer:
12.56
Step-by-step explanation:
The equation for the area of a circle is πr² (pi x r²). The first step is squaring r, the radius, which is 2. 2²=4. 4 x 3.14= 12.56
