Solving Problems Involving Quadratic Relations

Solve the following problems involving quadratic relations. You can choose to do so algebraically or graphically. If you choose to solve it graphically, you must attach a rough sketch of the graph from Desmos. If you choose to solve algebraically, SHOW ALL OF YOUR WORK.

 The path of a basketball jump shot can be modelled by the equation , where h is the height of the ball in feet and d is the horizontal distance from the basket in feet.
a) What was the maximum height reached by the basketball?
b) Estimate the height the jump shot was taken from
c) The rim of the basket is 10 ft above the ground. Did the ball go in
the basket? Explain

Imagine that a patient arrives at the medical office you work at and is sick, vomiting, in pain, or even injured and bleeding. This is the first time the patient has been seen by your office. The office is filled with patients who need to be seen and the phone is ringing as other patients call to schedule appointments. The patient walks up the counter and... Given this scenario, explain how you, as a Medical Office Assistant, would respond.

A. Name the element B. Is it a metal or a nommetal?

C. In ionic bonding is it likely to lose or gain electrons? D. What will the charge be

on an ion of this element? E. In what group of the periodic table does this element

belong?

Teachers can act as trailblazers in the lives of pupils. They can affect eternity. But the advancement of technology has changed the role of a teacher.

Write an article on the paradigm shift in educational technology and the role of teachers.

The accompanying drawing shows part of the orbital diagram for an element. 
(a) As drawn, the drawing is incorrect. Why? 
(b) How would you correct the drawing without changing the number of electrons? 
(c) To which group in the periodic table does the element belong?

Write a class called PocketChange that models a handful of change you might find in your pocket. The class has the following specifications:
Instance Variables - all instance variables are private

o int toonies - the number of toonies in the user's pocket o int
loonies - the number of loonies in the user's pocket o int
quarters - the number of quarters in the user's pocket o int
dimes - the number of dimes in the user's pocket o int nickels -
the number of nickels in the user's pocket o int pennies - the
number of pennies in the user's pocket Methods:

o PocketChange() - default constructor assigns 0 as a default value to all instance variables.

o PocketChange(toonies, loonies, quarters, dimes, nickels, pennies) - sets the values of all the instance variables to the programmer-specified parameter values.

o Accessor and mutator methods for each instance variable - all coin values must be 0 or positive values. Exceptions should be thrown if an attempt is made to set an instance variable to a negative value.

o calcAmount() - This method calculates and returns the total amount of money in the user's pocket, based on the values in each of the instance variables.

o toString() - returns a String with the following format:

o Toonies: t o Loonies: L o Quarters: q o Dimes: d

o Nickels: n Pennies: p where t, L, q, d, n, and p are the number of toonies, loonies, quarters, dimes, nickels and pennies. 

The minute hand on a clock is 10 mm long and the hour hand is 7 mm long. How fast is the distance between the tips of the hands changing at 6:45?

Please show all work and explain. Thanks.
