If you want to find the midpoint of A and B, then the formula you use is (A+B)/2. We add up the numbers and then divide by 2.
For instance, A = 1 and B = 5 leads to a midpoint of 3 since (A+B)/2 = (1+5)/2 = 6/2 = 3.
Visually we have found the average of the endpoints, which is at the center. So this shows that the midpoint is basically the average when you have 2 data values. We can extend this out to having more than 2 items to find the average. It might help to think of a dot plot and try to determine where the center of that data distribution is. The arithmetic mean is one way, but the median is also another tool.
Answer: In case you want to locate the midpoint of A and B, then the formula you use is (A+B)/2. We upload up the numbers and then divide through 2. For instance, A = 1 and B = 5 end in a midpoint of 3 considering
(A+B)/2 = (1+5)/2 = 6/2 = 3.
Visually we've discovered the common of the endpoints, which is at the center. So this indicates that the midpoint is largely the average if you have 2 facts values. we will make bigger this out to having extra than 2 objects to locate the average. it'd help to think of a dot plot and try and decide in which the center of that records distribution is. The arithmetic suggests is one manner, but the median is likewise any other tool.
Note: Hope this helps and am sorry for the late answer, it will help you in the future tho.

Find the value of x in the figure below. Brainlyest!
Answer:
x = 42°
Step-by-step explanation:
Fact: The sum of the exterior angles will be 360°.
(3x + 45) + (2x - 30) + (5x - 75) = 360
combine like terms:
10x - 60 = 360
add 60 to each side of the equation:
10x = 420
divide both sides by 10:
x = 42°
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second.
y=-16x^2+193+128
x = 6.03 seconds
Step-by-step explanation:
The equation of motion of the rocket is
y = -16x^2 + 193x + 128
We can determine its maximum height ymax when its vertical velocity y' reaches zero. Taking the derivative of y, we get
y' = -32x + 193
The value nen of x that makes y' will give us the time needed by the rocket to reach its maximum height ymax. So setting y' = 0 we get
x = 193/32 = 6.03 second
Bonus:
Putting this value of x into y, we'll get
y(x = 0.59s) = -(16 ft/s^2)(6.03 s)^2 + (193 m/s)(6.03 s) + 128 ft
= 710 ft

Find all the missing elements.
Round to the nearest tenth.
a = 5
b = 2
C = 6
A= [?]°
B = [ ]
C = [ ]
Answer: A= 51.3 B= 18.2 C=110.5
Step-by-step explanation:
The missing elements in the triangle are A ≈ 3.992°, B ≈ 170.008°, and c ≈ 5.4 units
To find the missing angle 'A', we can use the law of cosines, which states that for any triangle with sides 'a', 'b', and 'c' and opposite angles 'A', 'B', and 'C', the following relationship holds:
c² = a² + b² - 2ab * cos(C)
Plugging in the known values, we get:
c² = 5² + 2² - 2 * 5 * 2 * cos(6)
Now, we can solve for 'c':
c² = 29 - 20 * cos(6)
c² ≈ 28.8178
c ≈ √28.8178
c ≈ 5.4 (rounded to the nearest tenth)
Now that we have the value of side 'c', we can find angle 'A' using the law of sines, which states that for any triangle:
sin(A) / a = sin(C) / c
Plugging in the known values:
sin(A) / 5 = sin(6) / 5.4
Now, solve for 'sin(A)':
sin(A) = 5 * sin(6) / 5.4 sin(A) ≈ 0.0698
Now, find the value of angle 'A' using the inverse sine (sin⁻¹) function:
A ≈ sin⁻¹(0.0698)
A ≈ 3.992° (rounded to the nearest tenth)
Finally, to find angle 'B', we can use the fact that the sum of angles in any triangle is 180 degrees:
B = 180 - A - C
B = 180 - 3.992 - 6
B ≈ 170.008° (rounded to the nearest tenth)

A football field is a rectangle measuring 300 ft by 160 ft. each unit on a coordinate grid represents 1 foot. (0,0) and (0,160) are two of the coordinates of a football field drawn on the grid.What are the coordinates of the other two weeks?
Answer: (300,0), (300,160)
Step-by-step explanation:
Given
Dimension of the football field is [tex]300\ ft\times 160\ ft[/tex]
The length between (0,0) and (0,160) coordinates is 160 ft
Similarly, (0,0) and (300,0) represents the 300 ft of length
and (0,160) and (300,160) represents the 300 ft of length
Thus, the other two coordinates are (300,0) and (300,160)

Which is best to estimate the value of 0
===============================================================
Explanation:
There are three approaches we can take. Each approach uses a different column (sine, cosine, or tangent).
Let's go with the sine column. The sine ratio is opposite/hypotenuse.
For reference angle theta, the opposite sides is 8 meters. The hypotenuse is 12.5 meters. Dividing the two values gets us
opposite/hypotenuse = 8/12.5 = 0.64
While focusing on the sine column, we see that 0.64 isn't in there; however the value 0.6428 is fairly close to it. There's expected to be roundoff error somewhere. That value corresponds to theta = 40.
That must mean sin(40) = 0.6428 approximately is fairly close to 8/12.5 = 0.64
Or put another way,
sin(40) = 8/12.5 approximately

Answer:
It would be option 2.
Step-by-step explanation:
This is because option 1 does not have a irrational number that goes on indefinitely, option three has the square root of 25, which equals 5 meaning it is rational, and the last option also gives us rational choices. Therefore, the only possibility is that it would be option 2.
Luis's math teacher plots student grades on their weekly quizzes against the number
of hours they say they study on the pair of coordinate axes and then draws the line of
best fit. What is the meaning of the x-value on the line when y = 75?
Answer:
In the graph, we have a linear fit of the student's grades as a function of the number of hours they say that they study.
Then the y-axis represents the grade, and the x-axis represents the number of hours of study, and because this is a linear fit, we will have something like:
y = a*x +b
If we input a value of x here (number of hours studied) we would get the expected grade for the weekly quiz y.
In this situation, the meaning of the x-value on the line when y = 75 would be the (adjusted) number of hours studied to get a grade of 75.
So this x-value is the average number of hours that a student needs to study to get a grade of 75 points.

- If MML = (11x - 5), mJK = (4x + 26)° and mZMNL = (10x – 12),
find mZMNL.
Answer:
m∠ MNL = 78º
Step-by-step explanation:
Arcs meassures
mML = (11x - 5)º
mJK = (4x + 26)°
Angle meassure
m∠MNL = (10 x – 12)º
______________________
angle measure = average of arcs
m∠MNL = (mML+ mJK)/2
Replacing
(10x – 12)º = ((11x - 5)º + (4x + 26)° )/ 2
10x -12 = (15x + 21 )/2
10x - 7.5x = 10.5 + 12
2.5x = 22.5
x= 9
m∠MNL = (10 x – 12)º
= 90 - 12
