Explanation Given: The function is given, f ( x ) = x And at x = 9 there is a line tangent to the function f ( x ) = x . Formula used: Equation of line The general equation of the line tangent to the curve y = f ( x ) at the point ( x 1 , y 1 ) is, y − y 1 = m ( x − x 1 ) Where, m is the slope of line tangent. ( x 1 , y 1 ) is the point at line. Calculation: Substitute 9 for x in curve of f ( x ) = x , y = f ( 9 ) = 9 = 3 So, the point ( x 1 , y 1 ) at tangent is ( 9 , 3 ) . Slope of the line tangent is equal to the derivative of function f ( x ) at point ( 9 , 3 ) , m = f ' ( x ) | ( 9 , 3 ) The derivative of the function f ( x ) which limits exist, is, f ' ( x ) = lim h → 0 f ( x + h ) − f ( x ) h (1) Substitute ( x + h ) for x in function f ( x ) = x , f ( x + h ) = ( x + h ) Substitute the values of f ( x + h ) = ( x + h ) and f ( x ) = x in equation (1) to find the value of f ' ( x ) , f ' ( x ) = lim h → 0 ( <

An engineer is designing a pipeline which is supposed to connect two points P and S. The engineer decides to do it in three sections. The first section runs from point P to point Q, and costs $48 per mile to lay, the second section runs from point Q to point R and costs $54 per mile, the third runs from point R to point S and costs $44 per mile. Looking at the diagram below, you see that if you know the lengths marked x and y, then you know the positions of Q and R. Find the values of x and y which minimize the cost of the pipeline. Please show your answers to 4 decimal places. 2 Miles x = 1 Mile R 10 miles miles y = miles
