If f(x)=x squared +4x-5
show that (x-3) is a factor of the polynomial h(x)=f(x)-f(3)
Answer:
To show that (x-3) is a factor of the polynomial h(x) = f(x) - f(3), we need to use the definition of a polynomial factor. A polynomial factor is a polynomial that, when multiplied by another polynomial, results in the original polynomial.
First, let's evaluate f(3) to find the value of h(3).
h(3) = f(3) - f(3) = 0
Now let's examine the value of h(x) for any x other than 3.
h(x) = f(x) - f(3)
If (x-3) is a factor of h(x), then for any value of x other than 3, h(x) should be equal to zero.
So,
h(x) = (x-3)g(x)
where g(x) is another polynomial.
Therefore, by definition, (x-3) is a factor of h(x) = f(x) - f(3).

Step-by-step explanation:
Split the shape up into pieces. If you make an invisible cut vertically from the 14 ft length you will realise you have a small triangle attached to a rectangle.
You can assume that the height of the triangle is equal to the 20 - 14 as the left side must equal the right side for this shape thus this invisible length is equal to 6 ft
Area of triangle: (6ft x 6ft)/2 = 18 ft^2
Area of rectangle: 20ft x 8ft = 160 ft^2
Area of total shape = 160 + 18 = 178ft

If point A
and point B
are located 12
feet apart and are both at ground level, what is the approximate height of the tree to the nearest foot?
feet
Answer:
44 ft
Step-by-step explanation:
You want to know the height of a tree whose top is at angles of elevation of 42° and 50° from points 12 feet apart.
TangentThe tangent of an angle is related to the side lengths of a right triangle by ...
Tan = Opposite/Adjacent
This tells us the length of the side adjacent to the angle of elevation is ...
Adjacent = Opposite/Tan
ApplicationHere, the height of the tree is the side of the triangle opposite the angle of elevation, and the difference of adjacent sides is 12 ft:
12 = h/tan(42°) -h/tan(50°)
h = 12/(1/tan(42°) -1/tan(50°)) ≈ 12/(1.11061 -0.83910) ≈ 44.197
The approximate height of the tree is 44 feet.
Fill The Blank ?a function is a rule that assigns to each value of the_____
In essence, a function is a rule that assigns to each value of the input set (also known as the domain), a unique value of the output set (also known as the range).
A function is a fundamental mathematical concept that is used to describe the relationship between two sets of values.
To understand the idea of a function, imagine a machine that takes in an input and produces an output. The input values are the domain of the function, and the output values are the range. A function can be represented as an equation, a graph, or a table. For example, the equation f(x) = x + 3 represents a function that takes in an input value x and produces an output value that is 3 greater than the input value.
One of the key features of a function is that each input value must have a unique output value. This means that if you input the same value into the function twice, you should get the same output value both times. In mathematical terms, we say that a function is well-defined if it has a unique output value for each input value.
Functions are used in a wide range of mathematical applications, from algebra and calculus to statistics and data analysis. They provide a powerful tool for describing and analyzing relationships between different sets of values.

An airplane climbs at an angle of 40 degrees with the ground. What is the ground distance it has traveled (to the nearest 100 ft) when it has attained an altitude of 2400ft
The airplane has traveled a ground distance of 2900 ft when it has attained an altitude of 2400 ft at an angle of 40 degrees with the ground.
Determine ground distanceThe ground distance that the airplane has traveled can be found using the trigonometric function of tangent. The tangent of an angle is the ratio of the opposite side to the adjacent side in a right triangle. In this case, the opposite side is the altitude (2400 ft) and the adjacent side is the ground distance we are trying to find.
We can use the formula:
tan(angle) = opposite/adjacent
Plugging in the given values:
tan(40) = 2400/adjacent
Solving for the adjacent side (ground distance):
adjacent = 2400/tan(40)
Using a calculator, we can find the value of tan(40) and then divide 2400 by that value to get the ground distance:
adjacent = 2400/0.8391
adjacent = 2860.67 ft
Rounding to the nearest 100 ft, the ground distance is 2900 ft.

The company plans to find the center of the data an give a 5% raise to the employees who have been employee for at least those number of years.Find the mean and median,and explain which will be better from the employees prescriptive.
Number of years of each employed {11,6,32,7,18,4,9,1,15,9,5,27}
The mean is 11.25 and median is 8, and from the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cut-off point.
The mean and medianTo find the mean and median, we can start by arranging the data in ascending order:{1, 4, 5, 6, 7, 9, 9, 11, 15, 18, 27, 32}
Mean:The mean is the average value of the dataset. We can find the mean by summing up all the values and dividing by the total number of values:
mean = (1 + 4 + 5 + 6 + 7 + 9 + 9 + 11 + 15 + 18 + 27 + 32) / 12
= 135 / 12
= 11.25
Therefore, the mean of the dataset is 11.25.
Median:The median is the middle value in the dataset. If the dataset has an odd number of values, the median is the middle value. If the dataset has an even number of values, the median is the average of the two middle values.
In this case, the dataset has 12 values, so we need to find the average of the 6th and 7th values:
median = (7 + 9) / 2
= 8
Therefore, the median of the dataset is 8.
From the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cutoff point. This is because the median is not affected by outliers as much as the mean.
In this dataset, the value of 32 is much larger than the other values and could skew the mean upward, which would result in a higher cutoff point for the raise. On the other hand, the median is not affected by the outlier and provides a better representation of the central value of the dataset.
A 5% raise for employees who have been employed for at least 8 years (the median) would be more fair and reasonable for all employees.

yearly inflation has averaged 2.46%. How much is Kendra's birthday
money worth now?
Because of the inflation of 2.46%, the $50 of Kendra is not worth of $62.3 after 10 years.
What is inflation?The amount that a collection of products and services have increased in price during a specific time frame, typically a year, is measured by inflation. One of the most well-known words in economics, perhaps.
Countries have experienced protracted periods of instability due to inflation.
Prices for goods and services are always subject to change in a market economy.
Some prices increase while others decrease.
When prices of products and services grow broadly rather than just for a few specific items, it is said to be inflation.
This means that today, for the same amount of money, you can buy less than you could yesterday.
So, we have: $50
Now, the inflation rate is 2.46%.
Then, 50/100 * 2.46
1.23
1.23 * 10
12.3
12.3 + 50 = $62.3
