If <3 measures 123°, what is the measure of <4?
The value of angle 4 is 57°
How to determine the angle
From the image shown, we can see that angle 3 and angle 4 are on a straight line.
It is important to note that angles on a straight line sum up to 180 degrees.
We have angles 1 and 2 are supplementary, that is, they sum up to 180 degrees
Angles 3 and 4 are also supplementary and sum up to 180 degrees
Angles 5 and 6 are also supplementary.
Then, if angle 3 = 123 , we have;
angle 3 + angles 4 = 180
123 + angle 4 = 180
Angle 4 = 180 - 123
Angle 4 = 57°
Thus, the value of angle 4 is 57°

F. 0.17
G. 0.33
H. 0.5
J. 0.67
The probability of getting a number that is greater than four is G. 0.33
Probability:
Probability defines the possible occurrence of the selected event across the total number of events.
Given,
A die is rolled.
And we need to find the probability of rolling a number greater than 4.
If you roll a single die there are 6 possible outcomes are
=> {1,2,3,4,5,6}
So, the numbers that are greater than 4 are,
=> 5 and 6.
So, there are 2 of which are greater than 4.
So in a single roll the probability of getting a number greater than 4 is
=> 2/6
=> 1/3.
For the decimal form it can be written as,
=> 0.33.
So, the correct option is G. 0.33.
Therefore, the probability of getting the number greater than 4 is 0.33.

The distance between X(5,4) and Y(2,1) is 4.24 rounded to the nearest tenth.
How to find the distance between two points?Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]

focus at (6,0)
The equation of the parabola that has vertex at the center and focus at the point (6,0) is x = y²/24
We define what a parabola is
What is a parabola?The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.
The canonical equation of a parabola is given by
(y - k)² = 4p(x - h)
The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.
Since the vertex and the focal axis are on the same axis, we analyze that:
v (0, 0)
f (6, 0) the focus is on the right so the parabola is of the form X = Y².
(y - 0)² = 4p(x - 0)
f = (0 + p, 0)
0 + p = 6
p = 0 + 6
p= 6
(y - 0)² = 4*6(x - 0)
(Y)² = 24(X)

Write a quadratic equation that passes through the points -2,8 1,14 0,10
By solving a system of equations we can see that the quadratic equation is:
y = x^2 + 3x + 10
How to write a quadratic equation that passes through the given points?
A general quadratic equation is given by:
y = a*x^2 + b*x + c
We want this quadratic equation to pase through the points (-2, 8), (1, 14), and (0, 10).
using the last point, we know that when x = 0, we must have y = 10, then:
10 = a*0^2 + b*0 + c
10 = c
So our quadratic equation is:
y = a*x^2 + b*x + 10
Now we use the other two points to write a system of equations:
8 = a*(-2)^2 + b*(-2) + 10
14 = a*(1)^2 + b*1 + 10
If we simplify these, we get:
-2 = 4*a - 2b
4 = a + b
Isolating a in the second equation we get:
a = 4 - b
Now we replace that in the other equation:
-2 = 4*(4 - b) - 2b
-2 = 16 - 4b -2b
-2 - 16 = -6b
-18/-6 = b = 3
Now that we know the value of b, we replace it in the equation for a:
a = 4 - b = 4 - 3 = 1
Then the quadratic equation is:
