Base on my calculations, the answer is not in the choices given. First, we have to acknowledge that the interest rate given is not the effective interest rate instead it is called the nominal interest rate therefore we have to convert it first to an effective interest rate. We use the following formula:
Effective Interest rate = [[1 + (r/m)]^m] - 1 where r is the nominal interest rate and m is the number of compounding times
For this case, m is equal to 2 since it is compounded semianually.
Effective Interest rate = [[1 + (.12/2)]^2] - 1 = .1236
We then use the calculated effective interest rate to the formula for the Compound Interest Rate Formula.
Future Value = Present Value (1 + Effective interest rate)^(no. of years)Future Value = 3000 (1 + .1236)^( 3) = 4255.56 dollars
Carets normally are used for an exponent so for example
2^3=8
Hope it helps feel free to ask question
Question 11 is C and also question 2 is A
19 feet
convert 2 
into an improper fraction
2 = 
hence the length of the wall is 19 feet
Answer: The axis of symmetry is x=1.
Explanation:
The given function is,
The degree of the equation is 2. SInce it is a quadratic function therefore the graph of the function is a parabola.
The axis of symmetry of a parabolic function 
is a vertical line,
Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,
Therefore, the axis of symmetry is x=1.
