a.
e^(0.05t)=1600
Answer: t=147.556
Show your work:
ln(e^(0.05t))=ln(1600)
0.05t=ln(1600)
(0.05t)/(0.05)=(ln(1600))/(0.05)
t=(ln(1600))/(0.05)
t=20ln(1600)
t=147.556

...MATH133 UNIT2: Quadratic Equations
Individual Project Assignment: Version 2A
Show all of your work details for these calculations. Please review this Web site to see how to
type mathematics using the keyboard symbols.
Problem 1: Modeling Profit for a Business
IMPORTANT: See Question 3 below for special IP instructions. This is mandatory.
Remember that the standard form for the quadratic function equation is y = f (x) = ax2 + bx + c
and the vertex form is y = f (x) = a(x – h)2 + k, where (h, k) are the coordinates of the vertex of
this quadratic function’s graph.
You will use P(x) = −0.2x2 + bx – c where (−0.2x2 + bx) represents the business’ variable profit
and c is the business’s fixed costs.
So, P(x) is the store’s total annual profit (in $1,000) based on the number of items sold, x.
1. Choose a value between 100 and 200 for b. That value does not have to be a whole
number.
2. Think about and list what the fixed costs might represent for your fictitious business (be
creative). Start by choosing a fixed cost, c, between $5,000 and $10,000, according to the
first letter of your last name from the values listed in the following chart:
If your last name begins with the letter
Choose a fixed cost between
A–E
$5,000–$5,700
F–I
$5,800–$6,400
J–L
$6,500–$7,100
M–O
$7,200–$7,800
P–R
$7,800–$8,500
S–T
$8,600–$9,200
U–Z
$9,300–$10,000

Managing Paediatric Illness and Injury
Level 2
1. Describe the common types of fractures and how to manage them.
Broken bone.
Based on the location and severity of the fracture, a broken bone usually must be set into position and supported until it is strong enough to bear weight. Your physician will recommend the most proven treatment approach, usually casting or surgery
2. Describe how to manage a dislocation
Relieve pain around the dislocation by applying a cold pack to the area; this will also reduce swelling that can add to discomfort injury. Keep joint immobile and do not try to push the bone back in place. Offer ibuprofens if in severe pain, monitor the patient until the professionals arrive.
3. Describe how to recognise and manage the following head injuries:
A concussion: you get dizziness, nausea, loss of memory, mild headache, seeing "stars", double vision, numbness and lack of hand-eye coordination.
B skull fracture: you will probably see an external wound or bruise on the head and there may be a depression visible on the scalp. Check behind the ears for swelling or bruising. There may be loss of clear fluid or watery blood through an eye or nostril, blood in the white of the eye, a black-eye, and the symmetry of the head or face may be disrupted. The responsiveness of the victim may deteriorate
C cerebral compression: levels of response deteriorate; headaches tend to be intense;...

Circular Flow
In the textbook, there are two circular flow diagrams. One represents the flows in the macro-economy as a closed system and the other represents the flows as an open system. The circular flow diagrams show how money travels through the economic systems including businesses, households, foreign agents and governments (Editorial Board, 2013). Within the closed and open systems there are two consumers. The first consumers are households that buy goods and services and the second consumers are those businesses that purchase factors to produce. Households enter the goods market while the businesses enter factor markets.
The first type of circular flow is that of the closed macro-economy system. This is the circular flow of money. A closed system is an economic model that counts only domestic exchanges but not the foreign agents. This therefore means that without foreign agents, the government or the economy is free of leakages. This system is basically shut off from surrounding environments and is self-contained. An example of a closed system would be the Earth system as a whole. Although energy passes across the Earth’s system boundary, no mass is exchanged throughout the Earth’s system and the rest of the universe (Ritter, M., 2011).
The second type of circular flow in the macro-economy is considered the open system. The open system is the opposite of the...

Answer: x = 5, x = -2
(x+5)(x+2) = 0
x = -5
x = -2
b) [pic]
Answer: x = 0, x = 2
3x(x-2) = 0
x = 0
x = 22) If [pic], find:
a) f(2)
Answer: f(2) = -3
[pic]
b) f(-3)
Answer: f(-3) = 42
[pic]
3) Solve [pic] using the quadratic formula.
Answer: x = -1/2, x = 2
[pic]
4) Use the graph of [pic] to answer the following:
[pic]
a) Without solving the equation, or factoring, determine the solution(s) to the equation [pic] using only the graph.
Answer: x = -1, x = 5
The line crosses the x axis at -1 and 5.
b) Does this function have a maximum or a minimum?
Answer: Maximum
All the y values are below 8 so it is the maximum point.
c) What are the coordinates of the vertex in (x, y) form?
Answer: (3, 8)
d) What is the equation of the line of symmetry for this graph?
Answer: x = 3
5) a) Calculate the value of the discriminant of [pic] .
Answer: -11
[pic]
b) By examining the sign of the discriminant in part a, how many x-intercepts would the graph of [pic]have? Why?
Answer: No x-intercepts. Discriminant is negative.
