The quadratic function f(x) has roots of −4 and 2 and point (1, −5) lies on f(x). What is the equation of f(x)?
f(x) = (x − 2)(x + 4)
f(x) = (x − 2)(x − 4)
f(x) = 4(x − 2)(x + 4)
f(x) = 4(x − 2)(x − 4)
The equation of the quadratic function f(x) is f(x) = (x + 4)(x - 2)
How to determine the equation of f(x)?From the question, we have the following parameters:
Roots = -4 and 2
Point = (1, -5)
Rewrite the given parameters as
Roots: x = -4 and x = 2
Point: (x, y) = (1, -5)
Recall that:
x = -4 and x = 2
This gives
x + 4 = 0 and x - 2 = 0
Multiply the equations
So, we have
y = a(x + 4)(x - 2)
When (x, y) = (1, -5), we have
-5 = a(1 + 4)(1 - 2)
This gives
a = 1
Substitute a = 1 in y = a(x + 4)(x - 2)
y = (x + 4)(x - 2)
Hence, the equation of f(x) = (x + 4)(x - 2)

The scatterplot below shows the number of hours that some high school students spend on working and on video games.
A graph title Working and Video games has weekly working hours on the x-axis and weekly hours of video games on the y-axis. Points are grouped together and decrease.
Which statement about the scatterplot is true?
In general, the number of hours spent working does not affect the number of hours spent on video games.
In general, the amount of weekly time spent working is equal to the amount of weekly time spent on video games.
As the amount of time spent working increases, the amount of time spent on video games increases.
As the number of hours spent working increases, the amount of time spent on video games decreases.

Suppose the vectors \( \bar{i}, \bar{j}, \bar{p} \) and \( \bar{q} \) are all unit vectors and the angle \( \theta=222^{\circ} \). Find the cartesian vector form of \( \bar{F}=(-31 \bar{i}+102 \bar{j}
The cartesian vector form of \(F\) is \(F = (-31cos(\alpha )i + 102sin(\alpha )j)\). We call x + yi the Cartesian form for a complex number.
Given that \(i,j,p\) and \(q\) are unit vectors and the angle \(\alpha = 222\)°, we can express the cartesian vector form of \(F\) as \(F = (-31cos(\alpha )i + 102sin(\alpha )j)\).
To calculate the components of \(F\) , we use the trigonometric functions \(cos(\alpha )\) and \(sin(\alpha )\) with the given angle \(\alpha = 222\)°.
\(cos(222) = -0.766\\sin(222) = -0.643\)
Substituting these values into the cartesian vector form, we have:
\(F = (-31cos(222)i + 102sin(222)j)\\F = (-31 * -0.766i + 102*-0.643j)\\F = (23.746i - 65.586j)\)
Therefore, the cartesian vector form of \(F\) is \(F = (23.746i - 65.586j)\).
The cartesian vector form of \(F = (23.746i - 65.586j)\)

Janelle invests in a piece of art that cost 600 British Pounds. A study found that art appreciates in value at a rate of 3.97% per year. Assuming this pattern continues, how much, in British Pounds, will Janelle's piece of art be valued at after 10 years? Round your answer to the hundredths place.
Enter your answer in the box.
British Pounds
Answer:
It will be worth about £885.59.
Step-by-step explanation:
The art piece originally costs £600.
And it appreciates at a rate of 3.97% each year.
And we want to find the value of the art after 10 years.
We can write an exponential function to model the situation. The standard exponential function is given by:
\(f(t)=a(r)^t\)
Where t is the time in years.
Since it appreciates at a rate of 3.97% each year, the value after each year will be (100% + 3.97%) or 103.97%.
103.97% = 1.0397. So, r = 1.0397:
\(f(t)=a(1.0397)^t\)
Our a is the initial value. Therefore:
\(f(t)=600(1.0397)^t\)
Then the value of the piece of art after 10 years is:
\(f(t)=600(1.0397)^{10}=885.5879...\approx \pounds 885.59\)
It will be worth about £885.59 after 10 years.
Answer:
885.59
Step-by-step explanation:
1. 600 + 23.82
2. 623.82 + 24.77

Container a was filled with water to the brim. then, some of the water was poured into an empty container b until the height of the water in both containers was the same. find the new height in both water containers
After pouring some water from container A into container B, the new height of the water in both containers will be equal.
When container A is filled with water to the brim, it reaches its maximum capacity. Let's assume the initial height of the water in container A is h.
When some water is poured from container A into container B, the water level in both containers will gradually equalize until they reach the same height. Let's denote this new height as H.
The reason the water levels equalize is due to the principle of fluid equilibrium. When the containers are connected and the water is allowed to flow, the water seeks a common level. This occurs because the pressure at the same height in a fluid is equal.
Therefore, after pouring water from container A to container B, the final height of the water in both containers will be H, which indicates that the water has reached an equilibrium point where the pressure is equal in both containers.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 95 miles per hour. The westbound train travels at 115 miles per hour. How long will it take for the two trains to be 336 miles apart? Do not do any rounding.
Answer:
It will take 1.6 hours for the two trains to be 336 miles apart.
Step by step explanation:
Given that:
Speed of eastbound train = 95 miles per hour
Speed of westbound train = 115 miles per hour
Combined speed = 95+115 = 210 miles
Distance = 336 miles
\(Speed = \frac{Distance}{Time}\\\\210 = \frac{336}{Time}\\\\Time = \frac{336}{210}\\\\Time = 1.6\ hours\)
Hence,
It will take 1.6 hours for the two trains to be 336 miles apart.

B. (3, 5), (8, 4), (10, 11), (10, 6)
C. (negative 2, 2), (0, 2), (7, 2), (11, 2)
D.(13, 2), (13, 3), (13, 4), (13, 5)
For choices A, B and D, the x values repeat in some way.
Choice A has x = 2 repeated
Choice B has x = 10 repeated
Choice D has x = 13 repeated
A function cannot have repeated x values. Put another way, a function is only possible if any given x input goes to exactly one y output.
Choice C shows each x value listed once only. If you were to graph these points, then the relation will pass the vertical line test.
let t be the set of all movie actors and actresses. for x, y t, define x r y if there is some movie that both x and y appear in. which properties of equivalence relations does r satisfy?
The relation "r" satisfies all the properties of an equivalence relation: reflexivity, symmetry, and transitivity.
The relation "r" defined on the set of all movie actors and actresses, denoted as "t," states that two actors/actresses are related if they have appeared in the same movie together. This relation satisfies the properties of an equivalence relation, namely reflexivity, symmetry, and transitivity.
1. Reflexivity: For any actor/actress x in the set t, x is related to itself because every actor/actress appears in at least one movie, including their own. Therefore, the relation "r" is reflexive.
2. Symmetry: If actor/actress x is related to actor/actress y, it means they have appeared in the same movie together. Since the relation "r" is based on mutual appearances in movies, if x has appeared with y, then y has also appeared with x. Thus, the relation "r" is symmetric.
3. Transitivity: If actor/actress x is related to actor/actress y, and y is related to actor/actress z, it implies that there is a movie in which x, y, and z have all appeared together. As a result, x is related to z through the transitive property. Therefore, the relation "r" is transitive.
In conclusion, the relation "r" satisfies all the properties of an equivalence relation: reflexivity, symmetry, and transitivity.

We cannot say that the two events are independent since the probability of eating pizza and sushi together is not known. If the probability of eating both together is 0, then the events are mutually exclusive, and if the probability is greater than 0, then the events are dependent.
We cannot say that the events of Marco eating sushi and pizza are independent. Two events are independent if the occurrence of one does not affect the probability of the other. However, in this case, if Marco eats sushi for dinner, it reduces the probability that he will eat pizza for dinner since he never eats both together.
Similarly, if Marco eats pizza for dinner, it reduces the probability that he will eat sushi for dinner. Therefore, the events are not independent, and the occurrence of one event affects the probability of the other. In other words, the events are dependent.
