What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that a right triangle is formed by connecting coordinates (5, -2), (2, -3), and (-1, 6).
The area will be calculated as,
Side = √ [ ( -3 + 2 )² + ( -2 - 5 )² ]
Side = √ ( 1 + 49)
Side = √50
Base = √ [ ( 6 + 3 )² + ( -1-2)² )
Base = √ ( 81 + 9 )
Base = √100
The area will be calculated as,
Area = (1/2) x B x H
Area = (1/2) x √50 x √100
Area = (1/2) x √50 x 10
Area = 5 x √( 25 x 2 )
Area = 25√2 square units

The graph of a linear function is shown.
Which word describes the slope of the line?
• positive
• negative
O zero
O undefined
The slope of the line as shown in the graph of the linear function in the image below is: negative.
What is the Slope of a Line of a Linear Function?The slope of a line of a linear function = change in y/change in x.
The value of the slope would be positive if the graph increases upwards from your left to your right.
The value of the slope would be negative if the graph decreases downwards from your left to your right.
Thus, the slope of horizontal lines are always zero while the slope of vertical lines are undefined.
Therefore, the slope of the line as shown in the graph of the linear function in the image below is: negative.

Step-by-step explanation:
Relationship:
Complementary angles add up to 90 degrees
JKL + MNP = 90
Solve for x:
(2x - 3) + (5x + 2) = 90
7x - 1 = 90
7x = 91
x = 13
Solve for JKL:
JKL = 2x - 3
JKL = 2(13) - 3

Hi!
So to find out the slope, we can use the equation change in y value over change in x value -- or vertical change over horizontal change.
Find two points on the graph that line up exactly on the lines of the graph, like (20, 0) and (12, 0).
Then, take the change in y value (20-0 = 20) and divide it by the change in x value (0 - 12) to get -20/12, or -5/3.

Answer:
1/3
Step-by-step explanation:
Answer:
The probability of is rolling a 1 or a 6 on a die is [tex]\frac{1}{3}[/tex].
Step-by-step explanation:
Since there are six sides to a die, and there are two sides that are either 1 or 6, that means the probability of rolling a 1 or 6 is [tex]\frac{2}{6}[/tex] or [tex]\frac{1}{3}[/tex].

What is the surface area of cuboid?The surface area of a cuboid is the total area of all its surfaces. Since a cuboid is a three-dimensional solid shape, the value of its surface area depends on the dimensions of its length, width, and height. The change in any of the dimensions of a cuboid changes the value of the surface area of a cuboid. The surface area of a cuboid is expressed in square units.
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
According to the question
A cereal box has a height = 10 inches
A cereal box has a length = 8 inches
A cereal box has a width = 2 inches
Now ,
Applying the formula of Total Surface Area of Cuboid as cereal box is also a cuboid
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
substituting the values
Total Surface Area of Cuboid
= 2 (8*2 + 2*10 + 8*10)
= 2 (16 + 20 + 80)
= 2(116)
= 232 square inches
Hence, the surface area of the cereal box is 232 square inches

A and b are positive integers and a-b=2. Evaluate the following:
(27^1/3b)/ ( 9^1/2a)
(this is urgent)
(I have tried 1, 25, and 1/27. None of them are correct)
Answer:
[tex]\displaystyle\displaystyle \frac{27^{1/3b}}{9^{1/2a}}=\frac{1}{9}[/tex]
Step-by-step explanation:
We are given that a and b are positive integers such that:
[tex]a-b=2[/tex]
And we want to evaluate:
[tex]\displaystyle \frac{27^{1/3b}}{9^{1/2a}}[/tex]
First, note that 27 = 3³ and that 9 = 3². Therefore:
[tex]\displaystyle =\frac{(3^3)^{1/3b}}{(3^2)^{1/2a}}[/tex]
Simplify:
[tex]=\displaystyle \frac{3^b}{3^a}[/tex]
Using the quotient property of exponents:
[tex]=3^{b-a}[/tex]
From our given equation, we can divide both sides by -1 to acquire:
[tex]-a+b=-2\text{ or } b-a=-2[/tex]
Therefore:
[tex]=3^{-2}[/tex]
Hence, our answer is:
[tex]\displaystyle\displaystyle \frac{27^{1/3b}}{9^{1/2a}} =\frac{1}{3^2}=\frac{1}{9}[/tex]
Aiden invested $98,000 in an account paying an interest rate of 2 % compounded
continuously. Autumn invested $98,000 in an account paying an interest rate of 2%
compounded quarterly. After 11 years, how much more money would Autumn have in
her account than Aiden, to the nearest dollar?
Answer:
Aiden would have $67 more than Autumn.
Step-by-step explanation:
Aiden compounded continuously, which uses the formula: [tex]P(t)=P_oe^r^t[/tex]
Plugging in what we know about Aiden's investment: [tex]P(11)=98000e^0^.^0^2^*^1^1[/tex]
That gives us: 122115.5196
Autumn invested using regular compound interest, which has the formula: [tex]A=P(1+\frac{r}{t})^n^t[/tex]
Since Autumn's investment is getting compounded quarterly, n=4 because it gets compounded 4 times a year.
Plug in Autumn's investment: [tex]A=98000(1+\frac{0.02}{4})^4^*^1^1[/tex]
That gives us: 122048.5974
Now just subtract the two and round to the nearest dollar:
[tex]122115.5196-122048.5974=66.92215187[/tex]
OR
$67. Aiden would have $67 more than Autumn after 11 years.

Las longitudes que se forman entre los vertices y el centro de un poligono regular son por favor respondan :'c
Answer:
Las longitudes que se forman entre los vértices y el centro de un polígono regular son;
Los radios del círculo circunscrito
Step-by-step explanation:
Cada círculo de radio, 'r', tiene un polígono que se puede inscribir polígono regular que tiene 'n' lados, donde n ≥ 3 y viceversa, todos los polígonos regulares se pueden inscribir (dibujar) en un círculo, que luego se conoce como la circunferencia del polígono
Dado que un polígono regular se puede inscribir en un círculo, de modo que sus vértices descansen sobre la circunferencia del círculo, entonces el centro del polígono es el centro del círculo que lo circunscribe.
Por lo tanto, las longitudes (iguales) que se forman entre los vértices y el centro del polígono regular son el radio del círculo que lo circunscribe..
37 1/2 of what number is 60
37.5 is 60% of 62.5#
Explanation:
First, let's call the number we are looking for
