Justin wants to use 376 ft of fencing to fence off the greatest possible rectangular area for a garden. what dimensions should h

Rina8888 [55]

Let the length be x and the width be y
the perimeter of the rectangle will be:
2x+2y=376
thus
y=188-x
thus the area will be:
A(x)=x(188-x)
A(x)=188x-x^2

For maximum Area A'(x)=0
from Area we shall have
A'(x)=188-2x=0
solving for x we get:
x=94
thus the width will be:
188-94=94
thus for maximum area the length=94 ft and width=94 ft
Area=94*94=8836 ft^2
thus the answer is:
<span>c. 94 x 94; 8836ft </span>

URGENT!!! What happens to the graph of y=−x6−6x5+50x3+45x2−108x−108 as x heads toward ∞ and −∞?

mr Goodwill [35]

Using limits, the correct option regarding the end behavior of the function is given by:

A. as x→∞, y→−∞ as x→−∞, y→−∞.

<h3>How to find the end behavior of a function f(x)?</h3>

The end behavior is found calculating the limit of f(x) as x goes to infinity.

For this problem, the equation is given by:

$f(x) = -x^6 - 6x^5 + 50x^3 + 45x^2 - 108x - 108$

Since x goes to infinity, we consider only the term with the highest exponent, hence the limits are given as follows:

$\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} -x^6 - 6x^5 + 50x^3 + 45x^2 - 108x - 108 = \lim_{x \rightarrow -\infty} -x^6 = -(-\infty)^6 = -\infty$

$\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} -x^6 - 6x^5 + 50x^3 + 45x^2 - 108x - 108 = \lim_{x \rightarrow \infty} -x^6 = -(\infty)^6 = -\infty$

Hence the correct option is:

A. as x→∞, y→−∞ as x→−∞, y→−∞.
