Answer:
The coordinates of E are [tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex].
Step-by-step explanation:
The triangle ABC represents a right triangle as both sides AB and AC are orthogonal to each other. The side AB is in the y axis, whereas the side AC is in the x axis. The triangle is dilated with respect to the origin, in which point A is set.
Vectorially speaking, dilation is defined by the following operation:
[tex]P'(x,y) = O(x,y) + k\cdot [P(x,y) - O(x,y)][/tex] (1)
Where:
[tex]O(x,y)[/tex] - Point of reference.
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Dilated point.
[tex]k[/tex] - Dilation factor.
By applying this operation, point B becomes point D:
[tex]B(x,y) = (0,4)[/tex], [tex]D(x,y) = (0,6)[/tex]
[tex]D(x,y) = (0,0) + k\cdot [(0,4)- (0,0)][/tex]
[tex]D(x,y) = (0,0) + k\cdot (0,4)[/tex]
[tex](0,6) = (0,0) +(0,4\cdot k)[/tex]
[tex](0, 6) = (0,4\cdot k)[/tex]
[tex]k = \frac{3}{2}[/tex]
Lastly, we transform point C into point E by applying the same operation: [tex]C(x,y) = (3, 0)[/tex], [tex]O(x,y) = (0,0)[/tex] and [tex]k = \frac{3}{2}[/tex]
[tex]E(x,y) = (0,0) + \frac{3}{2}\cdot [(3,0)-(0,0)][/tex]
[tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex]
The coordinates of E are [tex]E(x,y) = \left(\frac{9}{2}, 0 \right)[/tex].

The adjacent sides of a rectangle are (2x – 1) and (x + 5). Find its area.
Answer:
2x²+9x-5
Step-by-step explanation:
Area of a rectangle = Length * Width
If the adjacent sides are 2x – 1) and (x + 5), the area is calculated as;
A = (2x – 1) * (x + 5).
A = 2x²+10x-x-5
A = 2x²+9x-5
Hence the area of the rectangle with the adjacent sides is 2x²+9x-5

Answer:
[tex]\sqrt{x+6}[/tex]
Step-by-step explanation:
So, there are a few things we need to go over to graph a function,
When a number is outside of a root, it changes the y value. For example:
y=[tex]\sqrt{x}+6[/tex]
With the +6, y will always be 6 higher than normal.
If it was -6, then y will always be 6 lower than normal.
What if the number is inside the root? Well, it works a little differently.
Instead of changing the y value, it changes the x value. For example:
y=[tex]\sqrt{x+6}[/tex]
So if you put a number in for x, lets say -6, wht would you get?
You would get -6+6=0
The square root of 0 is 0, so when x=-6, y=0
Normally, x would have to equal 0 for the y value to be 0.
So basically, when we see the number isnide of the root, we can think the our x coordinate being subtracted by that number.
This makes since, because if we subtract the +6 from x:
x-(+6)= x-6, and -6 is our x coordinate.
If it was -6 at the start, this would also work:
x-(-6)= x+6. So our x coordinate would start at 6.
Now, lets look at our graph.
As we can see, the x values start at -6, and the y values starts at 0.
This eliminates A and D, since the +6 would change the y value, not the x.
Remember that x-6 would make x a postive 6.
x+6 however, would make x a negative 6.
So we need x+6 in a square root.
This eliminates B, since it has a x-6, making the x coordinate postive 6, not negative 6.
So c is our answer.
Hope this helps!

Answer:
C/3rd one. (y=2x+4)
Step-by-step explanation:
In the equation y=mx+b, m=slope of the line and b=y-intercept. From the graph, we know the y-intercept is 4 so we can write y=mx+4. To find the slope: (0-4)/(-2-0) = (-4)/(-2) = 2. We can replace the m with 2 to get the final equation of y=2x+4 which is also the third answer.

Which point represents the outlier in the scatter plot?
OA (2,4)
OB. (5, 10)
OC. (9, 10)
OD. (10,9)
Answer:
(10,9) is the outlier in the scatter graph
The outlier in the scatter plot is (10, 9).
Option D is the correct answer.
What is a scatterplot?A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.
In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.
The position of each point on the graph represents the values of both variables for that particular observation.
We have,
In a scatterplot, an outlier is a data point that lies far away from the other data points in the plot.
Outliers can be identified as data points that are much higher or lower than the majority of the data points, and they can be seen as points that are separated from the other data points in the plot.
We see that,
Point (10, 9) lies far away from the rest of the points in the scatterplot.
Thus,
The outlier in the scatter plot is (10, 9).

Type the equation for the graph below.
please help!!!
Answer:
y = 1sin(3x)
Step-by-step explanation:
y = A sin( (2π/ω)x )
A is amplitude = 1
ω is period = 2π/3
------------------------------
y = 1sin( 2π / (2π/3) x)
y = 1sin(3x)
The equation for the graph with a sinusoidal wave, given an amplitude of 1, a period of 2π/3, and a phase shift of 0, is y = sin((2π/3)x).
The equation for a sinusoidal wave can be written as:
y = A * sin(ωx + φ)
In this case, we are given the values of amplitude (A = 1), period (ω = 2π/3), and phase shift (φ = 0).
The amplitude (A) represents the maximum displacement or height of the wave from the center line. In this case, it is 1.
The period (ω) represents the length of one complete cycle of the wave. The period is the reciprocal of the frequency, and in this case, it is 2π/3.
The phase shift (φ) represents any horizontal displacement of the wave. In this case, the phase shift is 0, indicating that the wave starts at its equilibrium position.
Using these values, the equation for the given graph would be:
y = 1 * sin((2π/3)x + 0)
Simplifying it further:
y = sin((2π/3)x)

Answer:
k = 11
Step-by-step explanation:
Given the points are collinear then the slopes between consecutive points are equal.
Using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)
m = [tex]\frac{-1-1}{1-5}[/tex] = [tex]\frac{-2}{-4}[/tex] = [tex]\frac{1}{2}[/tex]
Repeat with another 2 points and equate to [tex]\frac{1}{2}[/tex]
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (k, 4)
m = [tex]\frac{4+1}{k-1}[/tex] , then
[tex]\frac{5}{k-1}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
k - 1 = 10 ( add 1 to both sides )
k = 11

The total resistance in a circuit with two parallel resistors is 2 ohms and R1 is 6 ohms. Using the equation for R2, in terms of RT and R1, what is R2 R2 blank is ohms
[tex]R_2[/tex] is 3 ohms
Step-by-step explanation:In a circuit containing two resistors [tex]R_1[/tex] and [tex]R_2[/tex] connected together in parallel, the total resistance [tex]R_T[/tex] is given by;
[tex]\frac{1}{R_T} = \frac{1}{R_1} + \frac{1}{R_2}[/tex] ---------(i)
Make [tex]R_2[/tex] subject of the formula;
=> [tex]\frac{1}{R_2} = \frac{1}{R_T} - \frac{1}{R_1}[/tex]
=> [tex]\frac{1}{R_2} = \frac{R_1 - R_T}{R_TR_1}[/tex]
=> [tex]{R_2} = \frac{R_TR_1}{R_1 - R_T}[/tex] ---------------(ii)
From the question,
[tex]R_1[/tex] = 6Ω
[tex]R_T[/tex] = 2Ω
Substitute these values into equation (ii) as follows;
=> [tex]{R_2} = \frac{2*6}{6 - 2}[/tex]
[tex]{R_2} = \frac{12}{4}[/tex]
[tex]R_2[/tex] = 3Ω
Therefore, the value of [tex]R_2[/tex] = 3 ohms or [tex]R_2[/tex] = 3Ω
Answer: is 3 ohms.

Find the y-intercept of the quadratic function: g(x) = 5х2 + 9x + 4 о (0, 18) (4.0) ООО (0.4) (0,5)
Answer:
(0,4)
Step-by-step explanation:
Here, we want to find the y-intercept of the quadratic function
g(x) = 5x^2 + 9x + 4
Mathematically, we know that the y-intercept is the position on the graph where we have x = 0
so, to find the y-intercept value, we have to find g(0)
simply put, we have to substitute the value of 0 for x
Mathematically, we have this as;
g(0) = 5(0)^2 + 9(0) + 4
g(0) = 0 + 0 + 4
g(0) = 4
thus, we have the y-intercept point as (0,4)

Answer:
9
Step-by-step explanation:
Since we want the fewest number of groups possible, we need to maximize the number of people in each group. Since there can be a maximum of four people in each group, we can have a maximum of [tex]\left\lfloor \frac{35}{4}\right \rfloor=8[/tex] groups of four. The final three students can form the last group, hence the smallest number of groups possible is [tex]8+1=\boxed{9}[/tex]
