A 2 foot wide painting should be centered on a 14 foot wide wall. How many feet (x) should be on each side of the painting?

geniusboy [140]

Divide the length of the wall by 2 to find the center of the wall:14/2 = 7 feet

The center of the painting is 2/2 = 1 foot.

The edge of the wall would be the center of the wall minus the center of the painting:

7 - 1 = 6 feet.

There should be 6 feet on each side of the painting.

If log2 5 = k, determine an expression for log32 5 in terms of k.

lukranit [14]

Answer:

$log_3_2(5)=\frac{1}{5} k$

Step-by-step explanation:

Let's start by using change of base property:

$log_b(x)=\frac{log_a(x)}{log_a(b)}$

So, for $log_2(5)$

$log_2(5)=k=\frac{log(5)}{log(2)}\hspace{10}(1)$

Now, using change of base for $log_3_2(5)$

$log_3_2(5)=\frac{log(5)}{log(32)}$

You can express $32$ as:

$2^5$

Using reduction of power property:

$log_z(x^y)=ylog_z(x)$

$log(32)=log(2^5)=5log(2)$

Therefore:

$log_3_2(5)=\frac{log(5)}{5*log(2)}=\frac{1}{5} \frac{log(5)}{log(2)}\hspace{10}(2)$

As you can see the only difference between (1) and (2) is the coefficient $\frac{1}{5}$ :

So:

$\frac{log(5)}{log(2)} =k\\$

$log_3_2(5)=\frac{1}{5} \frac{log(5)}{log(2)} =\frac{1}{5} k$

Write the given differential equation in the form L(y) = g(x), where L is a linear differential operator with constant coefficie

Greeley [361]

Answer:

The differential equation will be like the one shown below

Step-by-step explanation:

Data:

Let the equation be given as:

y(4) + 8y' = 6

The equation will be expressed linearly as follows:

y(4) + 8 $\frac{dy}{dx} = 6$

$8\frac{dy}{dx}+ 4y = 6$

This is the linear form of the differential equation.
