The information below represents the cost of Cody's home ownership. What is his average monthly expenditure related to his home?
mortgage $1,255 per month
● taxes $2,881 per year
● insurance $156 per month
● HOA fees $320 per year
● utilities $475 per month
Answer:
Cody's average monthly expenditure related to his home is $2,152.75

Analyze the function’s graph to determine which statement is true.
Over the interval [–2.5, 0.5], the local maximum is 2.
As the x-values go to positive infinity, the function’s values go to negative infinity. The function is decreasing over the interval (–1, 0.75).
The function is negative for the interval [–2, 0]
The truth of the statements in the question can be verified by analyzing the function's graph over the stipulated intervals. Understanding concepts such as local maxima, the behavior of functions at infinity, an interval of decrease, and intervals where a function remains negative or positive are essential in this process.
Explanation:To determine which statement in the question is true, we need to analyze the function's graph. The statements included talk about specific behaviors of the function in different intervals of the x-axis.
The first statement mentions a local maximum of 2 over the interval [–2.5, 0.5]. You will need to locate this interval on the x-axis and see if 2 is indeed the highest y-value within this range. If there is a point on the function where the y-value is 2 and it is higher than all neighboring points, then this statement is true.
The second statement states that as the x-values go to positive infinity, the function's values go to negative infinity. This implies that as the function continues towards the positive direction on the x-axis, the y-values continuously decrease towards negative infinity. If the graph shows this, then this statement is true.
The third statement says the function is decreasing over the interval (–1, 0.75). This would mean that as x goes from –1 to 0.75, the y-values decrease. If you observe this on the graph, this statement is true.
The last statement asserts the function is negative for the interval [–2, 0]. If, for all x-values from –2 to 0, the corresponding y-values are below the x-axis (negative), then this statement is valid.

Curt drank 130 miligrams of caffeine.His body processes 7% of caffeine everyhour.If Curt's body processes 7% every hour, we just need to that 7% after each hour. Also, we know that 7% equals 0.07.
First hour.
[tex]0.07(130)=9.1ml[/tex]
The first hour, his body processed 9.1 miligrams, so it remains
[tex]130-9.1=120.9ml[/tex]
There's still 120.9 miligrams in his body.
Second hour.
[tex]0.07(120.9)=8.46ml[/tex]
[tex]120.9-8.46=112.44ml[/tex]
Third hour.
[tex]0.07(112.44)=7.87ml[/tex]

If a data set has an even number of data, is it true or false that the median is never equal to a value in the data set? explain.
The median is never equal to a value in the data set when the data set has an even number of data points.
The statement is true - if a data set has an even number of data points, the median will never be equal to a value in the data set. The median is the middle value in an ordered set of data. When there is an even number of points, there are two middle values, so the median is the average of those two values.
For example, if we have the data set (2, 4, 6, 8), the median would be (4 + 6)/2 = 5. As you can see, the median is not equal to any of the values in the data set.
In conclusion, the median is never equal to a value in the data set when the data set has an even number of data points.

A weather forecast predicts that the temperature in antarctica will decrease 8 degrees fahrenheit each hour for the next 6 hours. write and solve an inequality to determine how many hours it will take for the temperature to drop at least 36 degrees fahrenheit
It will take at least 5 hours for the temperature to drop by 36 degrees Fahrenheit.
To determine how many hours it will take for the temperature in Antarctica to drop at least 36 degrees Fahrenheit, you can set up an inequality. Let's call the number of hours it takes for the temperature to drop x.
Given that the temperature decreases 8 degrees Fahrenheit each hour, you can represent the temperature drop as:
8x
Now, you want this temperature drop to be at least 36 degrees Fahrenheit, so you can write the inequality:
8x ≥ 36
To solve for x, divide both sides of the inequality by 8:
x ≥ 36 / 8
x ≥ 4.5
So, it will take at least 4.5 hours for the temperature in Antarctica to drop by at least 36 degrees Fahrenheit.
Since time is typically measured in whole hours, it will take at least 5 hours for the temperature to drop by 36 degrees Fahrenheit.

when two object one of 10 pound weight and another of 2 pound is dropped from same height
condition 1 : when body fall In vaccum
When body fall in vaccum then there will be no effect of weight.
Both the body will hit the ground at the same time.
Condition 2 : when body falls in normal condition
When body falls in normal condition then in this condition the heavy weight object will fall first as the light weight object will have more air resistance than the heavy one.

Jorge is 1 year younger than his brother. The sum of their ages is no less than 25 years. Enter the youngest age Jorge's brother can be. Question 10 options:
12
13

15
The youngest age Jorge's brother can be is 13. This is derived from the given condition that the sum of their ages is no less than 25, by assigning Jorge's brother's age as an unknown 'x' and using algebraic principles.
Explanation:The subject question is a simple algebraic problem. Let's denote Jorge's brother's age as x, so Jorge's age would be x-1. The problem states that the sum of their ages is no less than 25, which would translate algebraically into x + (x-1) ≥ 25.
Then we simplify the equation by combining like terms, it turns into 2x - 1 ≥ 25. To isolate x, you first add 1 to both sides of the equation, which gives you 2x ≥ 26, and then divide both sides by 2, resulting in x ≥ 13.
Therefore, the youngest age Jorge's brother can be is 13.
