Presentation exercise 6 Write a function called num_of_digits which takes as input an integer and returns the number of digits in input number. For example, num_of_digits (6539) returns 4. Note that the input integer is not necessarily a positive number. Using this function, write another function (including docstring) called curious which takes as input an integer and returns true if the input represents a curious number, false otherwise. An n digit number is said to be curious if the last n digits of its square are equal to the original number. For example, curious (25) returns True, since 25 contains two digits and the last two digits of its square (625) are equal to 25.

(Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:
Create a function called midvalue that accepts three distinct int values as input and returns the value that is located exactly in the centre of the three. Thus, midvalue(5,28,14) yields 14.
fast please in pyth 10. Write a complete function. The name of the function is priceGuide, it has a single input parameter called avgPrice, and it has no return. The function is used to determine how expensive restaurants are, based on their average meal price (you can assume that the price is always larger than zero). If the average price is $10 or less, print the message “Inexpensive”. If the price is more than $10 but less than or equal to $30, print the message “Moderate”. If the price is more than $30, print the message “Pricey”. 9. Write a for loop to print all the even numbers contained in the range of 2 to 20, inclusive.
Exercise 4 A number, a, is a power of b if it is divisible by b and a/b is a power of b. Write a function called is_power that takes parameters a and b and returns True if a is a power of b. Note: you will have to think about the base case.

The food pantry provides its volunteers with keys to unlock doors and a Food Pantry vest to let customers know they work there. There are a limited amount of keys and vests, so volunteers need to check them out of the office.Complete the program by creating a CheckoutEquipment function that takes in the number of keys and vests currently available at the office. If there are enough keys and vests, the function should reduce the number of keys and vests by 1 and return true. Otherwise, the number of keys and vests will stay the same, and the function will return false. Take note that the number of keys and vests will be defined in the main function and the CheckoutEquipment function should modify the values of those variables declared in main. #include <iostream> int main() { int keys = 10; int vests = 10; bool checked_out = CheckoutEquipment(keys, vests); if (checked_out) { std::cout << "Successfully checked out.\n"; } else { std::cout << "Not…
