A scalar and matrix multiplication problem
pentagon [3]

Answer:

\left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]

Step-by-step explanation:

The product of a scalar times the matrix involves the product of that scalar times each of the elements of the matrix, resulting on the multiplication by "-4" of each of the four elements as shown below. These new product values end up being the new matrix elements.

-4*\left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right] = \left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]

Solve the equation. Round to the<br> nearest thousandth.<br> 4e2x = 5<br> x = [?]
Svet_ta [14]

Answer:

x = 0.1116 (rounded to 4 decimal places)

Step-by-step explanation:

We need to isolate "e" first, so we do:

4e^{2x}=5\\e^{2x}=\frac{5}{4}\\e^{2x}=1.25

Solving these types of equations requires us to take the Natural Logarith (Ln) of both sides, so we have:

e^{2x}=1.25\\Ln(e^{2x})=Ln(1.25)

We can use the property of logarithms shown below to further simplify:

Ln(a^b)=bLn(a)

So, we have:

Ln(e^{2x})=Ln(1.25)\\(2x)Ln(e)=Ln(1.25)

We know Ln(e) = 1, thus now, we can replace it and solve for x:

(2x)Ln(e)=Ln(1.25)\\(2x)(1)=Ln(1.25)\\2x=Ln(1.25)\\2x=0.2231\\x=\frac{0.2231}{2}\\x=0.1116

So

x = 0.1116 (rounded to 4 decimal places)
