p(x) = x3 - 2x2 + 2x
What are the real and complex zeros of the equation
Answers
Given:
The polynomial is
[tex]p(x)=x^3-2x^2+2x[/tex]
To find:
The real and complex zeros of the equation.
Solution:
We have,
[tex]p(x)=x^3-2x^2+2x[/tex]
For zeros, p(x)=0.
[tex]x^3-2x^2+2x=0[/tex]
[tex]x(x^2-2x+2)=0[/tex]
[tex]x(x^2-2x+2)=0[/tex]
[tex]x=0\text{ and }x^2-2x+2=0[/tex]
The real value of x is 0. The equation [tex]x^2-2x+2=0[/tex] will give complex roots. Here, a=1, b=-2 and c=2.
Using quadratic formula, we get
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(1)(2)}}{2(1)}[/tex]
[tex]x=\dfrac{2\pm \sqrt{4-8}}{2}[/tex]
[tex]x=\dfrac{2\pm \sqrt{-4}}{2}[/tex]
On further simplification, we get
[tex]x=\dfrac{2\pm \sqrt{-1}\sqrt{4}}{2}[/tex]
[tex]x=\dfrac{2\pm 2i}{2}[/tex]
[tex]x=\dfrac{2(1\pm i)}{2}[/tex]
[tex]x=1\pm i[/tex]
Therefore, the real zero is 0 and the complex zeros are 1+i and 1-i.

Often scientists use rate of change equations in their study of population growth for one or more species. In this problem we study systems of rate of change equations designed to inform us about the future populations for two species that are either competitive (that is both species are harmed by interaction) or cooperative (that is both species benefit from interaction. Which system of rate of change equations below describes a situation where the two species compete and which system describes cooperative species? Explain your reasoning.
a. dx/dt= -5x + 2xy
b. dx/dt= 4x-2xy
c. dy/dt= -4y + 3xy
d. dy/dt= 2y-xy
Answers
Answer:
a: cooperative.
b: competitive.
c: cooperative.
d: competitive.
Step-by-step explanation:
The rate of change:
dx/dt
gives information about how the quantity x changes as a function of time.
If dx/dt > 0, the population x increases as the time passes.
if dx/dt < 0, the population x decreases as the time passes.
Now, let's analyze the options:
a) dx/dt= -5x + 2xy
in this case, x represents one population and y represents the other population. Where x and y should only be positive numbers because we can not have a negative population.
Notice that in this case, if y increases, then dx/dt increases.
Then we have cooperative species because the population y helps the growth of population x.
b) dx/dt = 4*x - 2*x*y
Similar to the previous case, but now as the value of y increases, the value of dx/dt decreases, then we have competitive species.
c) dy/dy = -4*y + 3*x*y
Notice that now we have the rate of change of y, in the right side, we can see that as x increases, also the rate of change dy/dt.
Then the population x helps to increase the population y, which means that the species are cooperative.
d) dy/dt = 2*y - x*y
Now as x increases, the value of dy/dt decreases, then these species are competitive.

Step-by-step explanation:
Inequalities are used to represent unequal expressions.
The inequality is: [tex]h \le 46[/tex]
The height (h) is said to be no greater than 46 inches.
The text "no greater than" means less than or equal to.
In inequalities, less than or equal to is represented with <=
So, the inequality is:

Tom has some toy cars. 25 of them are red. He has 35 more green cars than red cars. The remaining 15 toy cars are yellow. Tom decides to pack 5 toy cars of the same colour in a box. How many more boxes of red and green toy cars are there than boxes of yellow toy cars?
Answers
Answer:
Step-by-step explanation:
red = 25
green = 25 + 35 = 60
yellow = 15
red = 25/5 = 5
green = 60/5 = 12
yellow = 15/5 = 3
Red + green = 5 + 12 = 17 boxes
yellow = 3 boxes
17 - 3 = 14 boxes
There are 14 more boxes of red and green cars than yellow cars.

A group of students plotted the number of hours they worked at a cake shop during the holidays and the number of cakes they delivered in a week.
Graph shows 0 to 60 on x axis and y axes at increments of 10. The label on the x axis is Weekly Hours Worked, and the label on the y axis is Number of Cakes Delivered. Dots are made at the ordered pairs 12, 13 and 16, 15 and 20, 27 and 23, 21 and 26, 37 and 31, 29 and 35, 41 and 38, 46 and 42, 52 and 43, 49 and 45, 54 and 49, 51.
Which statement best describes the relationship between the number of hours spent working at the cake shop and the number of cakes delivered?
Greater hours worked, more cakes delivered
Fewer hours worked, more cakes delivered
Greater hours worked, fewer cakes delivered
There is no relationship between hours spent working and number of cakes delivered.

As the x value increases, the y value also increases. So as one increases the other increases.
