5. The following formula can be used to describe the dimensions of a loading ramp: h sin(0) where e is the incline angle of the ramp, h is the height of the ramp, and I is the length of the ramp. Write a program that calculates the needed length of a ramp given a desired incline and height. For example, given an incline of 9.5 degrees and a height of 0.5 m, a ramp needs to be 3.03 m in length. The program should prompt the user for the needed values and calculate and report the required length. The program should make use of the math library for the sin() function, and should use the macro M_PI for the value of a to convert degrees to radians (radians = degrees x ). %3D 180

(Mechanics) The deflection at any point along the centerline of a cantilevered beam, such as the one used for a balcony (see Figure 5.15), when a load is distributed evenly along the beam is given by this formula: d=wx224EI(x2+6l24lx) d is the deflection at location x (ft). xisthedistancefromthesecuredend( ft).wistheweightplacedattheendofthebeam( lbs/ft).listhebeamlength( ft). Eisthemodulesofelasticity( lbs/f t 2 ).Iisthesecondmomentofinertia( f t 4 ). For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ft
C++ Programming Exercise: A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: a. The total number of of units. b. The rent to occupy all the units. c. The increase in rent that results in a vacant unit. d. Amount to maintain a rented unit. The program then outputs the number of units to be rented to maximize the profit.
5.19 In Python Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value)) Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.
(Mathematical functions) a model of worldwide population, in billions of people, is given by this formula. Population = 6.0e0.02t Where t is the time in years (t=0 represents january 2000 and t = 1 represents january 2001). Using this formula, write a c++ program that displays a yearly population table for the years january 2005 through January 2010.
C++ Question, Write a Computer Code: Let l be a line in the x-y plane. If l is a vertical line, its equation is x = a for some real number a. Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept. If l passes through the point (x₀, y₀), the equation of l can be written as y - y₀ = m(x - x₀). If (x₁, y₁) and (x₂, y₂) are two points in the x-y plane and x₁ ≠ x₂, the slope of line passing through these points is m = (y₂ - y₁)/(x₂ - x₁).
A bullet train slows from a speed of 200 mi/hr to 150 mi/hr in one minute. Write a computer program that calculates the bullet train’s constant rate of acceleration and determines how long the bullet train will take to come to rest, given an initial speed of 200 mi/hr. (Hint: Use the equation a = vf - vi t where a is acceleration, t is time interval, vi is initial velocity, and vf is final velocity.) Write and call a function that displays instructions to the program user and a function that computes a, given t, vf, and vi. using c programming language

(Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.
(Numerical) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.
