8x^2+16=48
8x^2+16-16=48-16
8x^2=32
8/8x^2=32/8
x^2=4
square root of x^2=square root of 4
x=2
The value of x is 2


Note: Use the square root symbol where I wrote it in sentence; that is, if you are going to copy this.

You deposit $2000 into an account that pays 6% compounded monthly. a. How much money will you have in the account after 1 year?
Masteriza [31]

We have a deposit of $2000 into an account that pays 6% compounded monthly, after a year we will have:

\begin{gathered} \text{account}_{\text{year}}=2000\cdot(1+\frac{6}{100})^{12} \\ \text{account}_{\text{year}}=4024.4 \end{gathered}

The effective annual yield (EAY) will be:

\text{EAY}=\frac{account_{year}}{2000}-1=\frac{4024.14}{2000}-1=1.0122

The EAY is 101.22%

I'm not sure where to start and how to differentiate this.
Mazyrski [523]
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)]

NEED HELP IMMEDIATELY Which expression is equivalent to one over four n − 16?
Gemiola [76]

B. 1/4(n - 64)

Multiplying n and -64 by 1/4 leaves you with 1/4n - 16, the original equation.
