Triangle MNO has vertices with coordinates (–8, 2), (–5, 5), and (5, – 2).
Which of these equations represents the line that passes through point N and is perpendicular to the line passing through points O and M?
y = x + 3
y = x - 3
y = -x + 3
y = -x - 3
Answer:
i think its c
Step-by-step explanation:
The equation of a straight line is represented as: [tex]y = mx + c[/tex]
The equation of the line is: [tex](c)\ y = -x +3[/tex]
The coordinates are given as:
[tex]M = (-5,5)[/tex]
[tex]N = (5,-2)[/tex]
[tex]O = (-8,2)[/tex]
First, we calculate the slope of line MO using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{2-5}{-8--5}[/tex]
[tex]m = \frac{-3}{-3}[/tex]
[tex]m = 1[/tex]
The line that passes through N is perpendicular to MO.
This means that, the slope (m2) of the line is:
[tex]m_2 = -\frac 1m[/tex]
So, we have:
[tex]m_2 = -\frac 1{1}[/tex]
[tex]m_2 = -1[/tex]
The equation of the line is then calculated as:
[tex]y = m_2(x - x_1) + y_1[/tex]
Where:
[tex]m_2 = -1[/tex]
[tex]N = (5,-2)[/tex] --- [tex](x_1,y_1)[/tex]
So, we have:
[tex]y = -1(x -5) - 2[/tex]
[tex]y = -x +5 - 2[/tex]
[tex]y = -x +3[/tex]
Hence, the equation of the line is: [tex](c)\ y = -x +3[/tex]

An infinite geometric series contains consecutive terms 262.4, 209.92, 167.963 and the sum is 1640. What is the first term?
Answer:
328
Step-by-step explanation:
[tex]\frac{a}{1-r}[/tex] is the equation for the sum of an infinite geometric series, where [tex]a[/tex] is the first term of the infinite geometric series, and r is the common ratio between the terms. Here, we can find the common ratio between any consecutive terms. [tex]\frac{209.92}{262.4} = \frac{4}{5}[/tex]
Therefore, [tex]\frac{a}{1-\frac{4}{5}} = 1640[/tex].
This simplifies to [tex]5a = 1640[/tex]
Therefore, [tex]a = 328[/tex]

Six identical circles fit inside the rectangle as shown below. If the rectangle has a width of 15
units and a height of 10 units, what is the radius of each circle?
Answer:
The radius of each circle is 2.5 units
Step-by-step explanation:
Width of the rectangle = 15 units
Height of the rectangle = 10 units
6 identical circles fit inside the rectangle,
Two circles fit along the height of the rectangle.
Therefore, diameter of both the circles = Height of the rectangle
2d = 10
d = 5
Since, radius of a circle = [tex]\frac{\text{Diameter}}{2}[/tex]
= [tex]\frac{5}{2}[/tex]
= 25. units
Therefore, Option (4) will be the correct option.

Step-by-step explanation:
(a) [tex]3x-4y=24[/tex]
Let [tex]x=0[/tex]
[tex]0-4y=24\\\Rightarrow y=-6[/tex]

The lengths of the two diagonals of a rhombus are 6 cm and 8 cm. Find the length of its perimeter (in
cm)
Answer:
The perimeter of the rhombus is 20 cm
Step-by-step explanation:
Perimeter of a Rhombus
Given the lengths of the two diagonals of a rhombus, let's call them a and b, the perimeter of the rhombus is given by:
[tex]P=2\sqrt{a^2+b^2}[/tex]
The values of the diagonals provided by the question are a=6 cm, b=8 cm, thus the perimeter is:
[tex]P=2\sqrt{6^2+8^2}[/tex]
[tex]P=2\sqrt{36+64}[/tex]
[tex]P=2\sqrt{100}=2*10[/tex]
[tex]P=20\ cm[/tex]

Step-by-step explanation:
Ok, so it's asking for range, Range means The Highest number minus the smallest number.
What is the highest number? it's "2.3"
What is the lowest number? it's "-2.2"
so subtract those numbers and you get your answer!
Wait... why is the range 4.5? well, you do 2.3-(-2.2) when there are 2 minuses, you switch it to a + sign. so, 2.3+2.2=4.5!
