Next, find the horizontal asymptote, if any. This is done by determining the ratio of the degree of the polynomial in the numerator to the degree of the \[ g(x)=\frac{x^{2}-2 x-35}{x^{2}-36} \] degree of numerator degree of denominator

Use a Riemann sum to approximate the area under the graph of \( f(x)=4 e^{-x} \) on the interval \( 0 \leq x \leq 1 \) using \( n=5 \) subintervals with the selected points as the right end points. The area is approximately \( \square \) units. (Round to six decimal places as needed.)

Find the average rate of change of \( h(x)=-2 x^{2}-5 x \) from \( x=-4 \) to \( x=1 \). Simplify your answer as much as possible.

A national fast food company has just analyzed the effect of the latest sales promotion. It has determined that the sales decay for its milkshakes is given by \( S=285,000 e^{-0.7 x} \), where \( S \) is the weekly sales and \( x \) is the number of weeks that have passes since the end of the sales promotion. a) Determine the sales 2 weeks after the end of the promotion: Round answer to 2 decimal places. Sales \( =\$ \) b) If no new campaign is started, how many weeks after the end of the promotion will sales drop below 30,000 ? Round answer to 1 decimal place. Num. weeks =

7. c) \( \frac{1}{1+x}-\frac{2}{x^{2}-1} \)

1. \( y=\frac{x}{\sqrt[4]{25-x^{2}}} \)
