The given equation is a geometric sequence.
It has a common ratio. You can get it by dividing the number in the sequence by the number before it.

Just like r= 16/4= 4

Answer:

The amount that came is $\frac{-68}{3}$

Step-by-step explanation:

The computation is shown below:

According to the question, it is mentioned that

Multiply 4 by $-5\frac{2}{3}$

First open the equation in a fraction it would be $\frac{-17}{3}$

Now multiplied the above fraction by a 4

That gives the result of $\frac{-68}{3}$

Hence, the amount that came is $\frac{-68}{3}$

We simply multiply the 4 with the given fraction

Thus the above represents the simplest form of the fraction

Find the minimum value if f(x) = xe^x over [-2,0]

SashulF [63]

Given function:

$f(x)=xe^x$

The minimum value of the function can be found by setting the first derivative of the function to zero.

$f^{\prime}(x)=xe^x+e^x$ $\begin{gathered} xe^x+e^x\text{ = 0} \\ e^x(x\text{ + 1) = 0} \end{gathered}$

Solving for x:

$\begin{gathered} x\text{ + 1 = 0} \\ x\text{ = -1} \end{gathered}$ $\begin{gathered} e^x\text{ = 0} \\ \text{Does not exist} \end{gathered}$

Substituting the value of x into the original function:

$\begin{gathered} f(x=1)=-1\times e^{^{-1}}_{} \\ =\text{ -}0.368 \end{gathered}$

Hence, the minimum value in the given range is (-1, -0.368)
