Solutions

Chapter 1.6, Problem 45E
To determine

To find: How many miles to the right of the origin need to be moved before the height of the curve reaches 3 ft if the graph y=log2x is drawn on the coordinate plane with the scale, one unit equals one inch.

Expert Solution

Answer to Problem 45E

The distance has to be moved to the right of the origin is 1084587.7 miles.

Explanation of Solution

The given function is, y=log2x .

Since 1 ft = 12 inches, the curve reaches 3 ft which is equivalent to 36 inches.

So, substitute y=36 in the given function and then solve for x.

36=log2x236=2log2x[alogax=x]236=xx=68719476736

Thus, x=68719476736 inches.

Since 1 mile = 63360 inches, x1084587.7 miles.

Hence, the distance has to be moved to the right of the origin is 1084587.7 miles.
