Answer:

The answer would be $x < -2$ OR $x \ge 4$ .

Step-by-step explanation:

Do pay attention to the hollow circle from which $x < -2$ is found; that means the value of x does not include -2, and therefore the < sign is used.

Hope this helped!

Maslowich

Answer:

$\frac{dy}{dx}=3x^{3x}(lnx+1)$

Step-by-step explanation:

We are given that a function

$y=x^{3x}+1$

We have to find the derivative of the function

Let $u=x^{3x}$

$y=u+1$

Taking ln on both sides

$lnu=3xln x$

By using $lna^b=blna$

Differentiate w.r.t x

$\frac{1}{u}\frac{du}{dx}=3(lnx+x\times \frac{1}{x})=3(lnx+1)$

$\frac{d(lnx)}{dx}=\frac{1}{x}$

$\frac{d(u\cdot v)}{dx}=u'v+v'u$

$\frac{du}{dx}=3u(lnx+1)=3x^{3x}(lnx+1)$

Differentiate y w.r.t x

$\frac{dy}{dx}=\frac{du}{dx}$

Using the value of du/dx

$\frac{dy}{dx}=3x^{3x}(lnx+1)$

Suppose that a family wants to start a college fund for their child. If they can get a rate of 5.5% , compounded monthly, and wa

Angelina_Jolie [31]

In 20 years a family will be able to earn 35 450 dollars. The interest that they earned is 5.5% compounded monthly. Now, let's find out how much will they need to save monthly to get this amount in 20 year:
=> 12 * 20 = 240 months
=> 35 450 / 240 months = 147.7 dollars per month is the money with interest
Let's subtract the interest
=> 147.7 * 0.055 = 8.1 dollars.
=> 147.7 - 8.1 = 139.6 dollars per month.
