Answer:
A. y = 1/2x + 3
Step-by-step explanation:
y = mx + b
m is the slope, b is the y-intercept
since 1/2 is the slope we now have
y = 1/2x + b
y-intercept is (0,3) which means b = 3 since 3 is the y value
y = 1/2x + 3
the fibonacci sequence is found by adding the two numbers before it together. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... the 2 is found by adding the two numbers before it (1 1). the 21 is found by adding the two numbers before it (8 13). the next number in the fibonacci sequence is:
The next number in the Fibonacci sequence after 34 (found by adding 21 and 34) is 55.
The Fibonacci sequence is a series of numbers where each number is the sum of the two numbers preceding it. The sequence starts with 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... and continues infinitely. The number 34 is found by adding the two numbers before it (13 and 21), and the next number in the sequence is 55, which is the sum of 34 and 21. This pattern continues, with each subsequent number being the sum of the two numbers before it.

What is a general solution of a differential solution?
Answer: A general solution of a differential equation is a solution that contains all possible solutions of the equation, including all arbitrary constants. It provides a general form of the solution that can be customized to fit the specific conditions of the problem.
For example, the general solution of a second-order linear homogeneous differential equation of the form
y'' + p(x)y' + q(x)y = 0
is a combination of two linearly independent functions, often represented by y = c1y1(x) + c2y2(x), where c1 and c2 are arbitrary constants and y1(x) and y2(x) are two linearly independent solutions of the differential equation.
The general solution represents the most general form of the solution that takes into account all possible solutions, including all arbitrary constants. To find a specific solution, one must apply initial or boundary conditions to determine the values of the arbitrary constants.

A new mountain bike will cost p dollars. Maddie has saved $375 for a new mountain bike. Her grandmother will give her $215 to help pay of the new bike.
Which inequality can be used to find the possible price values, p, of new mountain bikes that Maddie can afford?
Price values, p, of new mountain bikes that Maddie can afford is 375 + 215 ≥ p
What is inequality?
Inequality is a relationship between two expressions or values that are not equal to each other.
The inequality that can be used to find the possible price values, p, of new mountain bikes that Maddie can afford is:
375 + 215 ≥ p
This inequality represents the total amount of money Maddie has saved and the amount her grandmother will give her being greater than or equal to the cost of the bike. If the left side of the inequality is greater than or equal to the right side, Maddie can afford the bike at that price.

oscar finally found his dog on the fourth day. if he searched in a for two days and b for two days (not necessarily in that order) what is the probability that he found his dog. alive?
the probability that he found his dog. alive is 15%.
What is probability?
The chance of an event can be calculated using the probability formula by simply dividing the favourable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anything between 0 and 1, as the favourable number of outcomes can never exceed the total number of outcomes. Probability theory is a branch of mathematics that focuses on calculating the likelihood that an event will occur. Probability measures how likely something is to happen.
if he searched in a for two days and b for two days
P(A) = 0.4
P(B) = 0.6
P(Dn D-1 F-1)= n n+2

after running a chi-square test using the actual values and expected values, a p-value of 0.0000005 is obtained. is there a statistically significant association between the variables?
Yes, there is a statistically significant association between the variables when a p-value of 0.0000005 is obtained after running a chi-square test.
The p-value is the probability of observing a test statistic as extreme as the one calculated, assuming that the null hypothesis is true.
In most cases, if the p-value is less than 0.05 (5%), it is considered statistically significant. This means that there is less than a 5% chance that the results observed in the chi-square test are due to random chance, and that there is likely a real association between the variables being tested.
In the case of a p-value of 0.0000005, this is much less than 0.05 and therefore, it can be concluded that there is a statistically significant association between the variables.
This means that the observed differences between the actual values and expected values are not due to chance, but rather, there is a strong relationship between the two variables being tested.

Answer:
Step-by-step explanation:
To find the function rule for the relationship between x and f(x), we can perform a linear regression analysis on the given data points. This can be done using a spreadsheet software or a statistical software. One way to do this is to use the equation of a straight line, which is y = mx + b, where y is the output (f(x)), x is the input, m is the slope, and b is the y-intercept.
The slope m can be calculated as:
m = (Δy / Δx) = (f(x2) - f(x1)) / (x2 - x1) = (9 - 6) / (3 - 0) = 3
The y-intercept b can be calculated as:
b = f(x) - mx = 6 - 3x
So the function rule is:
f(x) = 3x + 6
To graph the function, we can plot the given data points and then draw a straight line that passes through those points. The graph of the function should look like this:
[!graph of f(x) = 3x + 6]
The function rule for the relationship between x and f(x) can be found using a similar process. Using the given data points, we can calculate the slope and y-intercept:
m = (Δy / Δx) = (f(x2) - f(x1)) / (x2 - x1) = (-2 - (-3)) / (1 - 0) = 1
b = f(x) - mx = -3 - x
So the function rule is:
f(x) = x - 3
The graph of the function should look like this:
[!graph of f(x) = x - 3]
For the third example, we can find the function rule using a similar process:
m = (Δy / Δx) = (f(x2) - f(x1)) / (x2 - x1) = (6 - 4) / (2 - 1) = 2
b = f(x) - mx = 4 - 2x
So the function rule is:
f(x) = 2x + 4
The graph of the function should look like this:
[!graph of f(x) = 2x + 4]

The probability that three cards chosen at random from a standard 52-card deck that are not all the same color is 3/4.
Total number of combinations of three cards: There are 52 choose 3 = 22,100 ways to choose three cards from a standard deck of 52 cards.
Number of combinations that are not all the same color: There are two possibilities for the colors of the three cards:
a. Two red cards and one black card: There are 26 choose 2 ways to choose two red cards and 26 choose 1 ways to choose one black card, for a total of (26 choose 2) * (26 choose 1) = 325 * 26 = 8,450 combinations.
b. Two black cards and one red card: There are 26 choose 2 ways to choose two black cards and 26 choose 1 ways to choose one red card, for a total of (26 choose 2) * (26 choose 1) = 325 * 26 = 8,450 combinations.
The total number of combinations that are not all the same color is 8,450 + 8,450 = 16,900.
The probability that three cards chosen at random are not all the same color is:
P(not all the same color) = (number of combinations that are not all the same color) / (total number of combinations of three cards) = 16,900 / 22,100 = 3/4.
Therefore, the probability that three cards chosen at random from a standard 52-card deck are not all the same color is 3/4.

Joe is thinking of a number. Eleven more than one third of the number is -1. What is the number?
The number Joe is thinking of is -36.
To find the number Joe is thinking of, use algebraic expression and equation.
Let x be the number Joe is thinking of
According to the problem, "Eleven more than one third of the number is -1". We can translate this into an algebraic expression such as:
x/3 + 11 = -1
To find the value of x, we'll isolate it on one side of the equation:
x/3 = -12
Next, we'll multiply both sides of the equation by 3 to cancel out the fraction:
x = -36

The solution is
A) The vertical asymptote of the function f ( x ) is = -3
B) The holes in the graph of f ( x ) = ( 0 , 6 )
C) The horizontal asymptote of the function f ( x ) is = 6
What are Asymptotes?An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote. When graphing functions, asymptotes are typically not required
There are 3 types of asymptotes
Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k. Horizontal Asymptote is when the function f(x) is tending to zero
Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero
Slanting asymptote (Oblique asymptote) - It is a slanting line and hence its equation is of the form y = mx + b
here, we have,
Given data ,
Let the function be f ( x ) = ( 6x² + 6x - 36 ) / ( x² + 3x )
A)
Now , to find the vertical asymptote
To find the vertical asymptote of a rational function, we simplify it first to lowest terms, set its denominator equal to zero, and then solve for x values
So , when x² + 3x = 0
x ( x + 3 ) = 0
So , x + 3 = 0
x = 0 is a hole in the graph
x = -3 is the vertical asymptote
B) The hole in the graph is ( 0 , 6 )
C)
Now , to find the horizontal asymptote
If both the polynomials have the same degree, divide the coefficients of the leading terms
So , 6x² and x² are the polynomials having the same degree
So , the coefficients are 6 and 1
y = (leading coefficient of numerator) / (leading coefficient of denominator)
y = 6 is the horizontal asymptote
Hence ,
A) The vertical asymptote of the function f ( x ) is = -3
B) The holes in the graph of f ( x ) = ( 0 , 6 )

Answer fast pls, test The volleyball team is accepting donations and having a car wash to raise funds for an out-of-state tournament and to purchase new equipment. The team plans to use 30% of all donations and car wash proceeds for new equipment. The table shows the results from over the weekend where w represents the amount charged per car wash.
Day
Donations and
Car Wash Proceeds
Saturday 25w + 95
Sunday 19w + 115
If the team charged $5 per car wash, how much money will they have to spend on new equipment?
The team plans to use 30% of all donations and car wash proceeds for new equipment, so they will have $430 * 0.30 = $129 to spend on new equipment.
We can start by finding the total amount of money raised from the car wash and donations on Saturday and Sunday. If the team charged $5 per car wash, then the total amount of money raised from car washing on Saturday is 25 * 5 = $125. The total amount raised from donations and car washing on Saturday is $125 + 95 = $220. Similarly, the total amount of money raised from car washing on Sunday is 19 * 5 = $95. The total amount raised from donations and car washing on Sunday is $95 + 115 = $210. The total amount of money raised over the weekend is $220 + $210 = $430. The team plans to use 30% of all donations and car wash proceeds for new equipment, so they will have $430 * 0.30 = $129 to spend on new equipment. Next, we can find the total amount raised from donations over the weekend. On Saturday, the team raised $25 + 95 = $120 from donations. On Sunday, the team raised $19 + 115 = $134 from donations. So, the total amount raised from donations is $120 + $134 = $254. Finally, we can find the total amount the team raised over the weekend by adding the amount raised from car washes and the amount raised from donations: $220 + $254 = $474.
Since the team plans to use 30% of all donations and car wash proceeds for new equipment, they will have 0.30 * $474 = $142.20 to spend on new equipment.

Write the standard form of the quadratic function that has the indicated vertex and whose graph passes through the given point. Use a graphing utility to verify your result.
Vertex: (-1/3,-1) Point (0, -10/9)
The standard form of the quadratic function with the given vertex is f(x) = 9x² + 6x + 10.
What are Quadratic Functions?Quadratic functions are polynomial functions where the highest degree of the variable is 2..
The general form of a quadratic function is f(x) = ax² + b x + c.
We know that, graph of a quadratic function is parabola.
General equation of a parabola is a(x - h)² + k.
Here (h, k) is the vertex.
Given vertex = (-1/3, -1)
Substituting,
a(x - h)² + k = a(x + 1/3)² - 1
Also we have a point (x, y) = ((0, -10/9)
a(0 + 1/3)² - 1 = -10/9
a/9 - 1 = -10/9
a/9 = -1/9
a = -1
General form is -1(x + 1/3)² - 1 = -1(x² + 2/3 x + 1/9) - 1
= -x² - 2/3 x -10/9
= 9x² + 6x + 10
Hence the standard form of the function is f(x) = 9x² + 6x + 10

The picture below shows the graph of which inequality?
The graph shows the inequality x² ≤ 16
How find the inequality for the graph?An inequality is a relationship that makes a non-equal comparison between two numbers or other mathematical expressions e.g. 2x > 4.
Inequalities are often used to describe conditions or constraints in real-world problems.
You will notice that the values represented in the graph ranges from -4 to 4. Thus, solving x² ≤ 16 will produce these values. That is:
x² ≤ 16
x ≤ ±√16
x ≤ ±4
x ≤ -4 or x ≤ 4
