Consider the following two sum functions:
def sum_iter(x: int) -> int:
result: int
while x >= 0:
result += x

if x < 0:
return 0
else:
return x + sum_recur(x - 1)

Consider the call sum_iter(5). How many times would the while loop's bool expression
x >= 0 need to evaluate in this function call for it to complete?

Write the function truck_adjustment_factor(truck_proportion, terrain_type) that takes the proportion of trucks using the motorway and the terrain type as inputs and returns the adjustment factor that is used for calculating the highway capacity. The adjustment factor is calculated according to the following formula: adju stment factor = tprupurtime x(furtor-1) Where proportion is the proportion of trucks and the factor is the car equivalent factor for the given terrain. You should be calling your car_equivalent_factor function to get the factor - don't reinvent the wheel! For example, for rolling terrain and a truck proportion equal to 0.12: adjustment factor = 1/(1 + 0.12 x (4.0 - 1)) = 0.735 Notes: You should include (and call/use) your car_equivalent_factor function in your answer o In general, you should paste in your whole module so far in each question as later functions will call earlier functions. • You can assume the function will always be called with one of the three valid…
