. The area of a rectangle is 64 square inches. Express the perimeter P as a function of the w
2 answers:
Answer:
Step-by-step explanation:
The area of a rectangle is A = lw. If the area is 64, we sub it in to get 64 = lw.
If we want to express the perimeter in terms of w using that area expression, we solve the area for l:
The formula for the perimeter of a rectangle is
P = 2l + 2w
If we are to express it in terms of w, sub in the l value from the area:
which simplifies to
Because this is width and width is a distance measure, it can't ever be negative or 0, so the domain for w is w > 0.

Answer:
Horizontal asymptote of the graph of the function f(x) = (8x^3+2)/(2x^3+x) is at y=4
Step-by-step explanation:
I attached the graph of the function.
Graphically, it can be seen that the horizontal asymptote of the graph of the function is at y=4. There is also a <em>vertical </em>asymptote at x=0
When denominator's degree (3) is the same as the nominator's degree (3) then the horizontal asymptote is at (numerator's leading coefficient (8) divided by denominator's lading coefficient (2))
Answer:
x= 2
