Find the length of the line segment that joins the points (2,5) and (9,8)
Answer:
=5sqrt(2)
Step-by-step explanation:
The length of a line segment is given by
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt( (9-2)^2 + (8-5) ^2)
= sqrt(7^2 + 3^2)
= sqrt(49+9)
= sqrt(50)
=sqrt(2*25)
We know that sqrt(ab) = sqrt(a)sqrt(b)
sqrt(25)sqrt(2)
=5sqrt(2)
The answer is 5sqrt of 2
if f(x)=2x-7, then find f(8)
Final answer:
To find f(8) for f(x) = 2x - 7, plug 8 into the equation and simplify: f(8) = 2(8) - 7, which equals 9.
Explanation:
To find the value of the function f(x) at x = 8, you simply substitute the value of 8 into the function. Given f(x) = 2x - 7, substituting 8 for x gives us:
f(8) = 2(8) - 7
Now, multiply 2 by 8:
f(8) = 16 - 7
Then, subtract 7 from 16:
f(8) = 9
Therefore, the value of the function f(x) when x = 8 is 9.
based on the graph below, how would you describe the curve?
Answer:
It's A.
Step-by-step explanation:
For every value of x there is one value of y - we can draw a vertical line through any value of x and it will pass through only one value of y.
Therefore it is a one-to-one function.
Answer:
Option A
Step-by-step explanation:
The curve given is an increasing curve cutting x axis once and y axis once.
Any vertical line cuts only once the curve. Hence this is a function only.
We find that for every y in the range there is only one x corresponding to that.
Hence this curve is not a many to one curve. It is not linear because it is not a straight line. It is a function.
Hence only correct option is
a) The curve is a one to one function.

A college graduate expects to earn a salary of 60000 during the first year after graduation and receive a 4% raise every year after that what is the total income he will have received after ten years?
The college graduate will have received a total income of $699,848.22 after ten years, starting with a salary of $60,000 and increasing by 4% each year.
Explanation:To find the total income the college graduate will have received after ten years, we need to calculate the salary for each year and sum them up. The first year salary is $60,000. After that, the salary increases by 4% each year. To calculate the salary for each subsequent year, multiply the previous year's salary by 1.04. Here are the calculations for each year:
Year 1: $60,000Year 2: $60,000 * 1.04 = $62,400Year 3: $62,400 * 1.04 = $64,896Year 4: $64,896 * 1.04 = $67,491.84Year 5: $67,491.84 * 1.04 = $70,190.95Year 6: $70,190.95 * 1.04 = $72,999.66Year 7: $72,999.66 * 1.04 = $75,923.45Year 8: $75,923.45 * 1.04 = $78,967.79Year 9: $78,967.79 * 1.04 = $82,138.35Year 10: $82,138.35 * 1.04 = $85,440.18Now, sum up the salaries for each year:
Total income after ten years = $60,000 + $62,400 + $64,896 + $67,491.84 + $70,190.95 + $72,999.66 + $75,923.45 + $78,967.79 + $82,138.35 + $85,440.18 = $699,848.22
Therefore, the college graduate will have received a total income of $699,848.22 after ten years.
The college graduate will receive a total income of approximately $720,360 over ten years.
1. To calculate the total income a college graduate will receive over ten years with an initial salary of $60,000 and a 4% annual raise, we can use the formula for the sum of a geometric series.
Initial salary (first year): $60,000Annual raise: 4%The salary for each year can be expressed as a geometric sequence where the first term (a) is $60,000 and the common ratio (r) is 1.04.We need to find the sum of the first ten terms of this geometric series.2. The formula for the sum of the first n terms of a geometric series is given by:
Sum = a(1 - [tex]r^{n}[/tex]) / (1 - r)
3. Substituting the given values:
a = 60,000, r = 1.04, n = 10
Sum = 60,000 * (1 - [tex]1.04^{10}[/tex]) / (1 - 1.04)
Sum = 60,000 * (1 - 1.48024) / ( -0.04)
Sum = 60,000 * (-0.48024) / (-0.04)
Sum = 60,000 * 12.006
Sum ≈ 720,360
4. Total Income:
Thus, the total income received after ten years is approximately $720,360.
Write an equation in slope-intercept form for the graph of the line shown???????
the answer is y=3x-1
the 3 comes from the point moving 3 up and 1 right and the -1 comes from the y intercept
Answer:
y = 3x - 1Step-by-step explanation:
The slope-intercept form of the equation of a line:
y = mx + b
m - slope
b - y-intercept
From the graph we have the y-intercept: (0, -1). Therefore b = -1.
y = mx - 1
From the graph we have the second point (1, 2). Put the coordinates of this point to the eqution:
2 = m(1) - 1
2 = m - 1 add 1 to both sides
3 = m
Finally we have
y = 3x - 1
Given a square with side lengths represented by the function f(x)=2x+5, find the square.
A. 2x^2+10x+25
B. 4x^2+20x+25
C. 4x^2+20x+10
D. 2x^2+5x+10
Answer:
[tex]B. 4x^2+20x+25[/tex]
Step-by-step explanation:
The length of the side:
[tex]2x+5[/tex]
In a square all sides have the same length.
And the area of a square is given by the formula:
[tex]Area=(length)^2[/tex]
so, substituting that the length is [tex]2x+5[/tex]
[tex]Area=(2x+5)^2[/tex]
and we solve this squared binomial with the formula:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
in this case [tex]a=2x[/tex] and [tex]b=5[/tex]
thus, we get:
[tex]Area= (2x)^2+2(2x)(5)+(5)^2[/tex]
and solving:
[tex]Area=4x^2+20x+25[/tex]

Answer:
1-ELIMINATION.
2- SUBSTITUTION.
3- GRAPHING.
Step-by-step explanation:
Methods:
1- Elimination:
- Line up the variables.
- To cancel out one of the variables, you need to make that the coefficient of that variable opposite. For example:
[tex]\left \{ {{3x+y=1} \atop {-3x+4y=3}} \right.[/tex]
As you can see, the coefficient of x in the first eqation is 3 and -3 in the second option.
- Add the equations.
- Solve for the the variable that is still present.
- Substitute the value of the variable obtained into one of the original equations.
- Solve for the other variable.
2- Substitution:
- Solve for one of the variables from any of the equations of the system.
- Substitute into the other equation for that variable.
- Solve for the other varible to find its value.
- Substitute the value obtained into any of the original equations and solve for the other variable.
3- Graphing:
- Rewrite the equations as equtions of the line slope intercept form ([tex]y=mx+b[/tex], where m is the slope nd b the y-intercept).
- Graph each line.
- Then:
If there ir an intersection point of the two lines, then that point is the solution to the system
If the lines are the same, there are infinitely many solutions.
If the lines are parallel, then there is no solution
explain what opposites are and give examples of real world situations
Answer:
Opposites in the numbers world refer to numbers that have the same absolute value, but one is negative, while the other is positive.
For a real world example, consider if you have your friend 5 dollars. The amount you have in the transaction is the opposite of the amount he has in the transaction.
The opposite of a number X is that number that when added to X produces zero. The opposite of X is denoted with −X.
The opposite of a number has the same absolute value as the number but an opposite sign. For example, the opposite of 1 is equal to −1 because 1 + (−1) = 0.
The opposite of zero is zero. This is the only number whose opposite is equal to itself. So zero is the neutral element with regard to addition.
In turn, the opposite of a complex number corresponds to a rotation of 180°.

How does f(x) = 9x change over the interval from x = 4 to x = 5?
Answer: A
put x = 3 into f(x)=6x and you get f(x) = 18
Put x = 4 into f(x) and you get f(x) = 24
Subtract those two. 24 - 18 = 6
Also, f(x) = 6x it will always be 6 away from the next x you put into the equasion.
Or better said, it will be 6 more from 6x, because you are changing the x to X+1, hence,
6(x+1) = 6x + 6.
+6, it increases.

How do you find slope?
Answer:
rise/run
Example:
say the lines is going 3 up and 4 to either side, the slope would be 3/4 :)
Answer:
Step-by-step explanation:
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.
Let's say that points (15, 8) and (10, 7) are on a straight line. What is the slope of this line?
Step One: Identify two points on the line.
In this example we are given two points, (15, 8) and (10, 7), on a straight line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
It doesn't matter which we choose, so let's take (15, 8) to be (x2, y2). Let's take the point (10, 7) to be the point (x1, y1).
Step Three: Use the equation to calculate slope.
Once we've completed step 2, we are ready to calculate the slope using the equation for a slope.
We said that it really doesn't matter which point we choose as (x1, y1) and the which to be (x2, y2). Let's show that this is true. Take the same two points (15, 8) and (10, 7), but this time we will calculate the slope using (15, 8) as (x1, y1) and (10, 7) as the point (x2, y2). Then substitute these into the equation for slope.

A jar contains 4 red marbles, 4 green marbles, and 5 blue marbles.
If we choose a marble, then another marble without putting the first one back in the jar, what is the probability that the first marble will be blue and the second will be green?
Answer:
20/156 or 5/39
Step-by-step explanation:
the first part of the equation will be:
5/13 (5 is how many blue and 13 is altogether)
the next part of this equation is the green marble. Because we didn't put the blue marble back, the next part of the equation will be:
4/12 (4 is how many green and 12 is altogether now that one blue was taken out)
and from there, you multiply 5/13 with 4/12, with will give you 20/156, or 5/39 if you simplify.
