What is the solution to the equation below? Round your answer to two decimal places. 4*e^x=12.76

sveta [45]

Answer:

$x=1.16$

Step-by-step explanation:

we have

$4(e^x)=12.76$

Solve for x

That means ---> Isolate the variable x

Divide by 4 both sides

$(e^x)=3.19$

Apply ln both sides

$ln[(e^x)]=ln(3.19)$

Apply property of logarithms (power rule) left side

$(x)ln(e)=ln(3.19)$

Remember that

$ln(e)=1$

$x=ln(3.19)$

$x=1.16$

PLZZZ HELP Find the inverse of a 2x2 matrix Plz give answer .

liraira [26]

Answer:

$\left[\begin{array}{cc}-\frac{1}{2}&\frac{1}{6}\\-\frac{1}{2}&\frac{1}{3}\\\end{array}\right]$

Step-by-step explanation:

If a 2x2 matrix is given as:

$\left[\begin{array}{cc}a&b\\c&d\\\end{array}\right]$

The inverse is:

$\frac{1}{ad-bc}\left[\begin{array}{cc}d&-b\\-c&a\\\end{array}\right]$

Our matrix given is:

$\left[\begin{array}{cc}-4&2\\-6&6\\\end{array}\right]$

Using the formula, let's find the inverse:

$\frac{1}{ad-bc}\left[\begin{array}{cc}d&-b\\-c&a\\\end{array}\right]\\=\frac{1}{(-4)(6)-(-6)(2)}\left[\begin{array}{cc}6&-2\\6&-4\\\end{array}\right]\\=\frac{1}{-12}\left[\begin{array}{cc}6&-2\\6&-4\\\end{array}\right]\\=\left[\begin{array}{cc}-\frac{1}{2}&\frac{1}{6}\\-\frac{1}{2}&\frac{1}{3}\\\end{array}\right]$
