The formula for the trajectory of a ball is given by f(x)=xtanθ−12v20gx2cos2θ+y0 where x is a coordinate along the ground, g=9.81 is the acceleration due to gravity, v0 is the magnitude of the initial velocity which makes an angle θ with the x-axis, and (0,y0) is the initial position of the ball. Write a program to calculate the trajectory y=f(x) for 0≤x≤16, with y0=10, v0=10, θ=50∘. (Do Python trigonometric functions accept radians or degrees?) Let x vary between 0 and 16 with 101 points. You will need to:

Which action describes an aspect of technological design?

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given. b)the definition of max_balance should be removed since header files should not contain constants. c)the definition of cashregister should be removed since header files should not contain class definitions. d)the body of the get_monthly_balance function should be added to the header file.

All of these are true about using adhesive except: a. dissimilar materials can be joined. b. mixing tips are product and material specific. c. a specific application gun may be required. d. two-part adhesives are dispensed using two mixing tips
