Select all the statements below which are TRUE:
+256 +n³ + n²lg5 n = 0 (n² lgn)
On³√n+n³ lgn + (1gn)² = 0 (n³.5)
| n³ lg(n³) +5n+ 1000 = 0 (n³ lgn)
Onlgn +37n +1000 = (n√n)
□n² lg (n7) + 5n+ 1000 = w (nlgn)
50+/+Ign=0 (1)
On³ + lgn+2n = o(nª)
Exercise III: Catalan numbers
For n e N, denote by c, to be the number of ways to form a "mountain range" with n
upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance:
for n = 1, only UD is allowed, so c = 1;
• for n = 2, only UUDD and UDUD are allowed, so c2 = 2.
1. Check that c3 = 5 by writing down or drawing all possible options.
2. Consider the power series
+00
g(x) = 2
n=0
(by definition co =
1) called the generating function of the sequence (en). Justify
that cn < 4" for each n, and deduce that the radius of convergence of g is at least
1/4.
3. It can be show that for r E (-1/4, 1/4),
g(x) = 1+ xg(r)?
and therefore
1- VI
4.x
g(x) =
2.x
Use this formula and the known power series of V1+ x to write the first terms of
the power series expansion of g, in the form
g(x) = co + c1x + c2x2 + C3x + c4x* + ·..
Show how you obtain a few terms, but you do not need to show all computations
and you can use a calculator for fractions. Check that you recover co,…

The index provides a measure of the chilling effect of wind at a given air temperature. Windchill may be approximated by the formula: W 5 13.12 1 0.6215* t 2 11.37 *v0.16 1 0.3965 * t *v0.016 where v 5 wind speed in m/sec t 5 temperature in degrees Celsius: t <= 10 W 5 windchill index (in degrees Celsius) Write a function that returns the windchill index. Your code should ensure that the restriction on the temperature is not violated. Look up some weather reports in back issues of a newspaper in your university library and compare the windchill index you calculate with the result reported in the newspaper.arrow_forward
- Answer attached quesarrow_forwardQ3: Interplanetary Spaceflight Milan Tusk is the richest person in the universe. After devoting decades of his life to further our space exploration technologies, he’s finally ready to retire. Being a space enthusiast, the first thing he wants to do is visit n planets p1, p2, …, pn, in this order. He’s currently on planet p0. Milan knows that the distance between planets pi and pi + 1 (for 0 ≤ i < n) is d[i]light years. His spaceship uses 1 tonne of fossil fuels per light year. He starts with a full tank and can fill up his tank at any of the n planets (but he must not run out in between two planets). There’s a huge cost to set up the spaceship for refuelling. Due to financial constraints (he’s not THAT rich), he can fill up his tank at most ktimes. In order to save money and make his spaceship lighter, Milan is looking for the smallest possible fuel tank that enables him to complete his space travel and reach planet pn. What is the smallest tank capacity that enables him to do so?…arrow_forwardint x=10,y=12,z=13,w=10; X=X+2; //value of X Z=X++ +10; //value of x W=--y +3; //value of y and w and z W=W+X-1; //value of Warrow_forward
