Answer:

x = 4.55.

Step-by-step explanation:

Given : ln 3 + ln (4x) = 4.

To find : Solve round your answer to the nearest hundredth.

Solution : We have given that  

ln 3 + ln (4x) = 4.

By the logarithm rule : ln a + ln b = ln (ab).

Then,

ln 3 + ln (4x) = ln (3 * 4x )

ln 3 + ln (4x) = ln (12 x )

Then ,

ln (12 x ) = 4

Taking exponential both side

12x = e^{4}.

12 x = 54.59.

12 x = 54 .59

On dividing by 12 both sides

x = 4.55.

Therefore, x = 4.55.

Because all of the ending values are given in feet, find the window dimensions in feet. Convert the length of 3 feet, 9 inches s
MA_775_DIABLO [31]

Answer: 3.75 ft

Step-by-step explanation:

Here we are given the measure of the length of a window. Generally the length is given in the International System of units format (meters); however, in this case we are given the length in feet and inches:

3 ft+9 in

Now, before converting this whole measure to feet, we have to know that 1 ft=12 in, then we can perform the conversion:

9 in \frac{1 ft}{12 in}=0.75 ft

This means 9 in=0.75 ft

Hence:

3 ft+9 i=3 ft+0.75 ft=3.75 ft This is the measure of the length of the window in feet.
