What is triangle?
In mathematics, the triangle is a closed polygon shape which has three vertex as well as three sides. It consist of three forms depending upon the sides. If all the sides are different then it is scalene otherwise equilateral triangle.
According to the question, the given triangle parameters are as follows:
AC = 6 cm; AB = 15 cm; BC = 9 cm;
Using Pythagoras theorem, the right angle property can be checked:
Let us assume the triangle ABC, with three sides:
AB² + BC² = AC² ⇒ (15)² + (9)² = (6)²
The given parameters did not satisfied the right angle triangle conditions. Therefore, it is not a right angle triangle.

Answer:
not a triangle
Step-by-step explanation:
You want to know if side lengths AC=6 cm, AB = 15 cm, and BC = 9 cm will define a right triangle.
Triangle inequalityThe triangle inequality requires the sum of the two shortest sides of a triangle exceed the length of the longest side. Here the requirement for the given lengths to form a triangle is ...
6 cm + 9 cm > 15 cm . . . . . . . . false
The given side lengths do not satisfy the triangle inequality, so do not form any kind of triangle.
__
Additional comment
Side lengths of a right triangle will satisfy the Pythagorean theorem, so that would be the test for a right triangle. We used the triangle inequality here, because we noticed the short sides add up to the long side. We need go no further, because these lengths do not even form a triangle.
Belinda wants to invest $1,000. The table below shows the value of her investment under two different options for three different years:
Number of years 1 2 3
Option 1 (amount in dollars) 1100 1210 1331
Option 2 (amount in dollars) 1100 1200 1300
Part A: What type of function, linear or exponential, can be used to describe the value of the investment after a fixed number of years using option 1 and option 2? Explain your answer. (2 points)
Part B: Write one function for each option to describe the value of the investment f(n), in dollars, after n years. (4 points)
Part C: Belinda wants to invest in an option that would help to increase her investment value by the greatest amount in 20 years. Will there be any significant difference in the value of Belinda's investment after 20 years if she uses option 2 over option 1? Explain your answer, and show the investment value after 20 years for each option. (4 points)
A) The type of function that can be used to describe the value of the investment after a fixed number of years using option 1 and option 2 are respectively; Linear Function and Exponential function.
B) One function for each option to describe the value of the investment f(n), in dollars, after n years.;
Option 1; f(n) = n + 100
Option 2; f(n) = n + 100x
C) The amount from option 1 after 20 years would be 3000 and the amount from option 2 after 20 years would be 4900
How to solve Linear functions?A) For option 1, the linear function can be used to describe the value of the investment after a fixed number of years. This reason is that, in option one, the amount increases by a fixed amount every year.
For option 2, the exponential function can be used to describe the value of the investment after a fixed number of years. The reason is that, in option 2, the amount increase is higher than the previous year.
B) For option 1, the function is;
f(n) = n + 100
For option 2, the function is;
f(n) = n + 100x
C) After 20 years, the amount from option 1 would be 3000 and the amount from option 2 would be 4900. Thus, there is a difference of 1900.

write an equation for the line parallel to y 3x - 8 through the point (-2,-7)
Answer:
y = 3x - 1
Step-by-step explanation:
In order for lines to be parallel, they must have the same slope.
The slope of y = 3x - 8 is 3.
Now, we can solve it using point-slope form. Remember that m = 3, x₁ = -2 and y₁ = -7:
y − y₁ = m(x − x₁)
y - (-7) = 3(x - (-2))
y + 7 = 3(x + 2)
Distribute 3 and isolate y:
y + 7 = 3x + 6
y = 3x - 1

A unit rate means a rate for one of something.
The number of boxes packed in 18 hours is 216 boxes.
What is a unit rate?A unit rate means a rate for one of something.
We write this as a ratio with a denominator of one.
We have,
From the graph, we see that,
In 5 hours, there are 60 boxes packed.
This can be written as:
5 hours = 60 boxes
Similarly,
1 hour = 12 boxes
3 hours = 36 boxes
The number of boxes packed in 18 hours:
1 hour = 12 boxes
Multiply both sides by 18.
18 hours = 18 x 12 boxes
18 hours = 216 boxes
Thus,
The number of boxes packed in 18 hours is 216 boxes.

Answer:
After solving the inequality, we get:
[tex]x\leq -10[/tex]
With the plotted inequality given.
Step-by-step explanation:
Step 1: Manipulate and solve the inequality
The inequality is given as:
[tex]\frac{1}{2}x+8\leq 3[/tex]
Make [tex]x[/tex] the subject of the inequality to solve it:
[tex]\frac{1}{2}x+8\leq 3\\\\\text{Subtract 8 from both sides of the equation:}\\\frac{1}{2}x+8-8\leq 3-8\\\\\text{Simplify:}\\\frac{1}{2}x\leq -5\\\\\text{Multiply by 2 on both sides of the inequality:}\\2\times \frac{1}{2}x\leq -5\times 2\\\\\text{Simplify:}\\x\leq-10[/tex]
Step 2: Plot the inequality
After solving the inequality, we get:
[tex]x\leq -10[/tex]
Which means that [tex]x[/tex] consists of all values that are equal to and less than [tex]-10[/tex].
On a number line, when the inequality includes the value, it is denoted by a closed circle.
With all this information, let's plot the number line:
11. Aviation The number of active certified commercialpilots has been declining since 1980, as shown inthe table.a. Find a linear equation that can be used as a modelto predict the number of active certified commercialpilots for any year. Assume a steady rate of decline.
a. The line equation is given by:
[tex]y=mx+b[/tex]Where m is the slope of the line and b is the y intercep.
In this case y is the number of active pilots and x is the year.
In order to obtain the line equation of the function, you use the information about a pair of years in the given table, in order to calculate the slope of the line. You can select whichever two years with its number of active pilots.
For example, for years 1980 and 1990, you have that the pilots were 182,097 and 149,666 respectively.
To calculate the slope of the line, you use the following formula:
[tex]m=\frac{149,666-182,097}{1990-1980}=-3,243.1[/tex]Then, the slope of the line is negative.
If you consider the zero point of the year axis, as the year 1980, the y intercept of the function will the value of the active pilots in that years, which is 182,097.
Finally, the line equation is:
[tex]y=-3,243.1x+182,097[/tex]b. For the year 2003, you have that x is:
x = 2003 - 1980 =23
You replace this value of x into the linear equation:
[tex]y=-3,243.1(23)+182,097=107506[/tex]The number of active pilots for 2003 is 107,506

How can we define the slope for a given line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. Therefore, the relationship between the change in the y-coordinate and the change in the x-coordinate is provided by the formula m = change in y/change in x = Δy/Δx, where "m" is the slope of a line.
Mathematically, slope of a line = m = (y₂ - y₁)/(x₂ - x₁)
What is the y-intercept for a given line?
When a graph crosses the y-axis, that location is known as the y-intercept. It is, in other words, the value of y at x=0.
What is the general equation of a line?
The equation for a standard line is y - y₁ = m(x - x₁), where m is the slope and c is the y-intercept.
Given, the line passes through the points (-2, 7) and (2, -5).
Now, using the formula established in the literature, we get:
Slope = m = (y₂ - y₁)/(x₂ - x₁) = (-5 - 7)/(2 - (-2)) = -12/4 = -3
Equation of the linear function: y - 7 = (-3)(x - (-2)) ⇒ y - 7 = (-3)(x + 2)
⇒ y - 7 = -3x - 6 ⇒ 3x + y = 1
Thus, the equation of the linear function is: 3x + y = 1.

The car will catch up the cyclist 3 hours after it starts moving.
In how many hours the car will catch up the cyclist?The cyclist travels at 9 miles per hour, and travels for 4 hours before the car starts moving, so the equation for the position of the cyclist as a function of time, t, is:

And the car moves at 21 miles per hour, then the position is:
P(t) = 21*t
The car will catch the cyclist when:
