Given f'(x) = (x-4)(4-2x), find the x-coordinate for relative maximum on the graph of f(x)
antiseptic1488 [7]

Answer:

The coordinate of the relative maximum is x=4.

Step-by-step explanation:

Given that the derivative of the function f(x) is f'(x) = (x-4)(4-2x), the maxima and minima or the critical points can be found where f'(x)=0, that is:

f'(x) = (x-4)(4-2x)=0.

The solutions to this equation are x=4 and x=2.

Now, if the second derivative f''(x) for a function f(x)  is negative at a critical point, then the critical point is the relative maximum.

Therefore we want to see at which of the two critical points is f''(x) negative. The second derivative is:

\frac{\mathrm{d f'(x)}}{\mathrm{d}x}=f''(x)=-4(x-3).

Now f''(4) is -4, and f''(2) is +4, therefore we deduce that the relative maxium is located at x=4, because there the second derivative f''(x) is negative.

Cesar is making a model of the Eiffel Tower. The height of the tower is 984 feet, and Cesar wants to make a 1.5-foot
n200080 [17]

Answer:

See below

Step-by-step explanation:

First, lets see how many feet of the original Eiffel tower (O) are represented in 1 foot of Caesar's tower model (M). We know that 1.5 foot is equal to 984 feet of the original, so we can say:

1.5 M = 984 O, this is our equivalence.

Now divide both sides by 1.5

1.5 M / 1.5 = 984 O / 1.5

1 M = 656 O

So, 1 foot of Cesar's Model is 684 feet of the original tower. We also know that 1 foot is equal to 12 inches, so we can say that 12 inches of Cesar Model (12 m) are equivalent to 656 feet of the original tower. So:

12 m = 656 O

If we divide both sides by 12:

m = 656/12 O

m = 56.67

So, 1 inch in Cesar's model represent 56.67 feet of the original Eiffel Tower.

Lets verify our result by multiplying 56.67 by 12 to get 1 feet and then by 1.5 to get the measure of the model:

56.67*12*1.5 = 984 feet, which is the height of the Eiffel tower.

Scale: 1 inch = 56.67 feet
