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

$(4$ 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 $(2r)$

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

$,\text{'}v\text{'}-$ 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 $(5,{?}^{\text{'}}{c}^{\text{'}})31\mathrm{.}416a,bc(a,b,c)$:$(1,0,-9)$

$(7$ 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

level$-$up$.$

Signature:

$(10$ 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 $(10,59,12,11)72(4,38,2,2)150$
