The correct option will be: d. 0.4%
For finding the periodic interest rate , we need to divide the annual interest rate by the number of times interest calculated in a year.
Here, the simple interest is calculated monthly, that means the number of times interest calculated in a year will be 12.
Annual interest rate is 4.8%
So, the periodic interest rate = 
%
1 is the magnitude of this question bro because it is process
Answer: She is incorrect because 0 + 0 = <u>0</u>
The answer would be -5 1/4
The picture is not clear. let me assume
y = (x^4)ln(x^3)
product rule :
d f(x)g(x) = f(x) dg(x) + g(x) df(x)
dy/dx = (x^4)d[ln(x^3)/dx] + d[(x^4)/dx] ln(x^3)
= (x^4)d[ln(x^3)/dx] + 4(x^3) ln(x^3)
look at d[ln(x^3)/dx]
d[ln(x^3)/dx]
= d[ln(x^3)/dx][d(x^3)/d(x^3)]
= d[ln(x^3)/d(x^3)][d(x^3)/dx]
= [1/(x^3)][3x^2] = 3/x
... chain rule (in detail)
end up with
dy/dx = (x^4)[3/x] + 4(x^3) ln(x^3)
= x^3[3 + 4ln(x^3)]
