TASKS

$(5$ pts$)$ Write a function called $ab$ val $()$ that returns the absolute value of a number. Do not

use the built$-$in absolute value function from the math library.

Signature:

def ab$\_$val $(x)$ :

#your code

return abval$(5)5$

abval$(-3\mathrm{.}55)3\mathrm{.}55$

$(4$ pts$)$ Write a function called circ$\_$calc $()$ that returns the specified measure of a shape

from two parameters: the radius and the measure sought. Round your answers to the nearest

thousandth. Use $=3\mathrm{.}14159.$

$\text{'}$c$\text{'}-$ circumference $(2)$

$\text{'}$a$\text{'}-$ area using $(r^2)$

$,v\text{'}-$ volume of a sphere $(\frac{4}{3})(r^3)$

If the measure parameter is not any of these, return$-1.$

Signature:

def circ$\_$calc$($radius$,$ shape$)$:

#your code

return

$(5$ pts$)$ Write a function called kind$\_$of$\_$roots $()$ that describes the roots of a quadratic

function from the coefficients $a,b,$ and $c.$

A function has "two real" roots when the discriminant is positive.

A function has "one real" root when the discriminant is zero.

A function has "two imaginary" roots when the discriminant is negative.

Use your discriminant $()$ function from previous PAs to calculate the value. $($Paste the

function into this file!$)$

Signature:

def kind$\_$of$\_$roots$($a$,$ b$,$ c$)$:

#your code

return

$(7$ pts$)$ Write a function called stock$\_$advice $()$ that determines what to do with a particular

stock from its purchase price and its current price. The first parameter is the purchase price and

the second is the current price.

The advice is "BUY" when the stock is up more than $30\%.$

The advice is "SELL" when the stock is down more than $50\%.$

For a stock that isn't changing very much $($up more than $30$ or down less than $50\%),$ the

response should be "HOLD".

Signature:

def stock$\_$advice$($start$\_$price, end$\_$price$)$:

#your code

return $(250\mathrm{.}09,466\mathrm{.}75)$

$(8$ pts$)$ Write a function called level$\_$up $()$ that determines if a video game player has enough

points to get to the next level, given a number of points and the current level. The return value

should be a Boolean.

A player needs to have more than a hundred times the next level's number in order to

level$-$up$.$

Signature:

def level$\_$up $($points$,$ level$)$:

#your code

return $(435,2)(555,8)$

$(5$ pts$)$ Write a function called level$\_$up$2()$ that determines if a video game player has

enough points to get to the next level, given a number of points, the current game level, and

their expert level. The return value should be a Boolean.

'beginner' : needs more than one hundred times the next level's number to level$-$up$.$

'intermediate': needs more than $200$ times the next level's number to level up$.$

'expert' : needs more than $500$ times the next level's number to level$-$up$.$

'pro': needs moge than a thousand times the next level's number to level up$.$

Signature:

def level$\_$up$2($points$,$ level, expert$\_$level$)$:

#your code

return $$

$(10$ pts$)$ Write a function called minutes passed $()$ that determines the number of minutes

between a start time and an end time. The function takes four parameters representing the

hour and minutes for the start time and the hour and minutes of the end time.

Signature:

def minutes$\_$passed $($h$1,$m$1,$h$2,$m$2)$:

#your code

#return $(9,15,11,45)150(10,59,12,11)=>72(4,38,2,2)$
