question 23

Multiple Choice

Solve the problem.
-Consider the area of the region in the first quadrant enclosed by the curve $y = \frac { 1 } { 8 } \cosh 8 x$ , the coordinate axes, and the line $x = 6$ . This area is the same as the area of a rectangle of a length s, where $s$ is the length of the curve from $x = 0$ to $x = 6$ . What is the height of the rectangle?

• A) \(\frac { 1 } { 8 }\)
• B) \(\sinh 48\)
• C) \(\frac { 1 } { 64 } \sinh 48\)
• D) 8
