Anit [1.1K]

Let 0.25x is the price increase. Therefore, the number of attendees will be 350-10x and the revenue R=(350-10x)*(5+0.25x)=1750+37.5x-2.5x^2. This parabola has maximum at x=10, meaning the price=7.5

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Temka [501]

Answer:

It diverges.

Step-by-step explanation:

We are given the inetegral: $\int\limits^{\infty}_2 \frac{1}{x} (\ln x)^2 dx$

$\int\limits^{\infty}_2 \frac{1}{x} (\ln x)^2 dx=\int\limits^{\infty}_2 (\ln x)^2 d(\ln x)=\\\\=\lim_{t \to \infty} \int\limits^t_2 (\ln x)^2d(\ln x)=\lim_{t \to \infty} \frac{(\ln t)^3}{3} |^t_2=\infty-\frac{(\ln 2)^3}{3} =\infty$

So it is divergent.

If it took Carlos 1/2 hour to cycle from his house to the library yesterday, was the distance that he cycled greater than 6 mile

Dvinal [7]

Answer:

Step-by-step explanation:

Given

time taken by Carlos to cycle is $t=0.5\ hr$

For case (1)

Average speed $v_{avg}>16\ ft/s$

For $0.5 hr \approx 30\times 60=1800\ s$

Distance traveled $d=1800\times 16=28,800\ ft\approx 5.45\ miles$

Therefore Carlos might not be able to cover 6 miles with average speed of 16 ft/s

(2) $v_{avg}=18\ ft/s$

for 0.5 hr

distance traveled

$d=1800\times 18=32,400\ ft\approx 6.136$

Therefore Carlos might be able to cover more than 6 miles with $18\ ft/s$
