The function A = 15x - x2, where x is the width in yards, gives the area A of a llama pen in square yards. Make a table using 1/
Mnenie [13.5K]

Answer:

The width which gives the greatest area is 7.5 yd

Step-by-step explanation:

This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen

PtichkaEL [24]

Answer:

first find slope m

m=(4-2)/(2-3)

m= -2

so equation line is

y-y1=m(x-x1)

y-4=-2(x-2)

y-4=-2x+4

y=-2x+4+4

y=-2x+8

?=-2
