lim (3 sec x - 3 tan x)

x->pi/2

Find f.

Suppose that f : R ? R is continuous and that, if |x| ? 1, then f (x) ? f (0). Prove
that there is y such that, for all x in R, f (x) ? f (y).

Find f.

1)  In a recent survey of college freshman, 42% of students checked the box next to “exercise regularly”, 45% checked the box next to “eat five or more servings of fruits and vegetables a day”, and 21% checked the box “neither.”  Use the appropriate probability notation in your answers to each question.

First, put student responses in the appropriate boxes of our two-way relative frequency table:

Exercise (E)

Use the appropriate probability notation in your answers to each question.

a) What is the joint probability of randomly selecting a surveyed freshman who exercises and eats 5 servings of fruits and vegetables each day?

b)  What is the probability of selecting a freshman who exercises regularly or eats 5 servings of fruits and vegetables each day?

c)  What is the probability of a student not eating fruits or vegetables?

d)  What is the probability of a freshman not exercising regularly and not eating 5 servings of fruits and vegetables each day?

e)  Complete this conditional relative frequency table rounding to the whole nearest percentage (e.g. 12%).

Difference between VS Code and Android Studio Eel version when it comes to flutter program. See screenshot below. See line 22 on the left side of the screen is VS Code the right side is Android Studio

VS Code is ok with this line

initialRoute: '/tasklist',

while Android Studio is complaining about it and wants it to be replaced

as 

initialRoute: '/task-list',

Is there a reason why Android Studio would want a hyphen.

5. Describe the impact of the social changes of the 1960s on today's culture in America?

1. Find the mass of a sample of CCL4 with 5.90 x 10^20 particles.

The solubility of ammonium formate,NH4HCO2 , in 100. g of water is 102 g at 0 °C and 546 g at 80 °C. A solution is prepared by dissolving NH4HCO2 in 185 g of water until no more will dissolve at 80 °C. The solution is then cooled to 0 °C. What mass of NH4HCO2 precipitates? (Assume that no water evaporates and that the solution is not supersaturated.)

a. If 0.25 mol Na2CO3 completely reacts with excess HCl, how many moles of NaCl and CO2

will be produced, respectively?

b. If 6.02 x 1022 particles of NaBr completely react with excess Ca(OH)2, how many particles of NaOH will be produced?

c. If 204.45 g of NH3 is completed used up in the reaction, how many grams of (NH4)2SO4 will be produced?

d. If 1 mol C5H9O reacts with 2 mol O2, how many mol of CO2 will be produced?
