Alex17521 [72]

Answer:

a. The horizontal asymptote of y = 3.10 represents that the average cost per unit will approach $3.10 as the number of units produced increases.

Step-by-step explanation:

A certain company has a fixed cost of $200 per day. Then it costs the company $3.10 per unit to make its products.

So, the total cost will be,

Then average cost f(x) will be,

As this an equation of hyperbola (rectangular hyperbola).

Its vertical asymptote is (equating denominator to zero),

i.e y axis.

Its horizontal asymptote is (leading coefficient of numerator divided by leading coefficient of denominator),

As x approaches infinity, f(x) approaches 3.10.

Therefore, option a is correct.

Which statement is sometimes true:

Lelu [443]

Answer:

4. A rectangle is a square

Step-by-step explanation:

A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.
