Answer:
4%/ a interest compounded semi-annually
Step-by-step explanation:
The option that gives the lower interest rate payment would be more appropriate. to determine this calculate the effective interest rate
Effective annual rate = (1 + APR / m ) ^m - 1
M = number of compounding
(1 + 0.04/2)^2 - 1 = 4.04%
(1 + 0.04/12)^12 - 1 = 4.07%
the choice should be 4%/ a interest compounded semi-annually
This written as an expression is 7 >= w > -1
Hope this helps!
Could you take another photo with you zoomed a lil bit more so I can answer it?
Both A and C would be solutions to the equation.
In order to solve for this you must first get the equation equal to 0.
2x^2+5x+8=6 ----> subtract 6 from both sides
2x^2 + 5x + 2 = 0
Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.
a = 2 (because it is the coefficient to x^2)
b = 5 (because it is the coefficient to x)
c = 2 (because it is the end number)
Now we can plug these values into the quadratic equation.





or -1/2 for the first answer

or -2 for the second answer
