Answer:
y = cos(x)
Step-by-step explanation:
This graph of the cosine function has no shifting or scaling. It is a plain cosine function:
y = cos(x)
_____
<em>Additional comment</em>
It will be worth your time to learn to recognize the sine and cosine functions. They have a maximum of +1, a minimum of -1 and a period (horizontal distance between corresponding points) of 2π. The sine function is symmetrical about the origin. The cosine function is symmetrical about the y-axis. The maximum slope (near the zero-crossings) is 1.
Answer:
1.98
Step-by-step explanation:
In this problem, we are:
Given: ∠D = 26°, Hypotenuse (DF) = 4.5
To solve: EF
Now through the given, we are to focus on point D to solve for EF.
We need to find the relationship of point D to DF and EF.
The relationship here is sine.
Reason:
Through point D, DF is the hypotenuse and EF is the opposite side.
So let's solve this simply through algebra,
sin =
sin(26°) =
0.44 =
0.44 × 4.5 = EF
1.98 = EF
What is the mean and median of 3,1,6,3,6,6,8,2,4,5,5,6,6,3,4,7,9,3,6,10,8,6,5,8,6 I NEED HELP FAST

Answer:
Median = 6
Mean = 5.44
Step-by-step explanation:
Part 1: Median
So we calculate this problem's median by counting out how many total numbers there are then finding the "middle" number. In this case there are 25 numbers. [(n-1) / 2) +1], Plug 25 in as n --> 24/2 = 12 --> 12 + 1 = 13. =>
So the median of this set would be the 13th number. We can simply count it out and we find that 6 would be the 13th number in this set.
Part 2: Mean
Now we can calculate the mean (average) by adding all the numbers up then dividing by 25 (the amt. of numbers in the whole set). -->
To simply save time, I will just tell you the sum. So correct we if I'm wrong (there are a lot of numbers to add so I might have made a mistake somewere) but I got a total sum of 136 that is not our final answer though because we still need to divide the sum of our numbers by the amt. of numbers in the set (25) =>
136 / 25 = 5.44
And thus, our median is 6, and our mean is 5.44

Answer:
Measure of angle 2 = 82°
Step-by-step explanation:
m∠1 = (10 x + 8)°
m∠3 = (12 x - 10)°
2 lines are said to intersect to form 4 angles. And the labelling of the angles was done starting from top left, clockwise: the angles are 1, 2, 3, 4.
Find attached the diagram obtained from the given information.
Vertical angles are angles opposite each other when two lines intersect. As such, they are equal to each other.
Considering our diagram
m∠1 = m∠3
m∠2 = m∠4
Sum of all four angles firmed = 360° (sum of angles at a point)
m∠1 +m∠2 + m∠3 + m∠4 = 360°
m∠1 = m∠3
(10 x + 8)°= (12 x - 10)°
10x-12x = -10-8
-2x = -18
x= 9°
Also m∠2 = m∠4, let each equal to y
(10 x + 8)°+ y + (12 x - 10)° + y = 360
10x + 12x - 10 +8 +2y = 360
Insert value of x
22(9) -2 + 2y = 360
2y = 360-196
2y = 164
y = 82°
m∠2 = m∠4 = y = 82°
Measure of angle 2 = 82°
