What is the central angle measure of the sector in radians?
Answer:
13π/9 rad
Step-by-step explanation:
Given the following
Area of a sector = 26πcm²
radius of the sector = 6cm
Required
central angle measure of the sector in radians
Area of a sector = Ф/2π * πr²
26π = Ф/2π * πr²
26 = Ф(6)²/2π
26 = 36Ф/2π
2π = 36Ф/26
π = 18Ф/26
26π = 18Ф
Ф = 26π/18
Ф = 13π/9 rad
Hence the measure of the central angle in radians is 13π/9 rad

What are the coordinates of the circumcenter of this triangle?
Enter your answer in the boxes.
Answer:
The coordinate of the circumcenter of the given triangle is (4, -1)
Step-by-step explanation:
The circumcenter is found by the intersection of the perpendicular bisectors of a triangle as follows;
The vertices of triangle ΔABC are A(1, 1), B(1, -3), and C(7, -3)
The coordinates of the midpoint of segment AB is 1/2(1 + 1, 1 + (-3)) = (1, -1)
The slope of segment AB = ∞, therefore, the slope of the perpendicular to segment AB = -1/∞ = 0
The line representing the perpendicular to segment AB is y = -1
The coordinates of the midpoint of segment BC is 1/2(1 + 7, (-3) + (-3)) = (4, -3)
The slope of segment BC = 0, therefore, the slope of the perpendicular to segment BC = ∞, which is a vertical line parallel to the y-axis with equation, x = 4
Therefore, the coordinate of the circumcenter is the intersection of the lines y = -1, and x = 4, which is the point (4, -1).

What is the equivalent decimal form for
2/40?
Answer:
decimal form: 0.05
Step-by-step explanation:
To find decimals divide them, so 2 divided by 40 is 0.05.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. thank you and have a nice day!
Answer:
0.05
Step-by-step explanation:
40 x 10 = 400
2 x 10 = 20
400 ÷ 4 = 100
20 ÷ 4 = 5
5/100 = 5 ÷ 100 = 0.05

Please answer this please 9th grade math
Answer:
1st choice
Step-by-step explanation:
For it to be parallel it has to have the same slope
Line 2 and 3 doesn't have the same slope, one has a slope of 3 and the other is -3 so they are not parallel
Solve line 4 equation first
3y + 18 = x
3y = x + 18
3y/3 = x/3 + 18/3
y = 1/3x + 6, slope is 1/3 same with line 1 so therefore line 1 and 4 are parallel
Answer:
Lines 1 and 4 are parallel
Step-by-step explanation:
The image below shows the four lines graphed, and proves that lines 1 and 4 are parallel.
Hope this helps! :)
1/3 (2 + 4) -6 = 2/3 (5 - z)
Answer:
11
Step-by-step explanation:
You can simplify everything on the left side of the equation first.
1/3 (2 + 4) - 6 = -4
-4 = 2/3 (5 - z)
Multiply both sides by 3/2 (multiplying by the reciprocal of 2/3 gets rid of the fraction)
(3/2) * -4 = 2/3 (5 - z) * (3/2)
-6 = 5 - z
-11 = -z
z = 11

Which of the lines below has a slope of zero?
B
D
OA. Line A
OB. Line B
OC. Line C
OD. Line D
Answer:
The answer is B but ima add this bc i need points :P
Step-by-step explanation:
The slope of line B is zero. option B is correct.
Graph of lines are shown, line with slope zero to be determine.
Slope of the line is given by m = tan[tex]\theta[/tex].
Here,
For line A the slope is m = ∞.
For line B the slope is m = 0.
For line C the slope is m = 1.
For line D the slope is m = -1.
Thus, the line with slope zero is line B.

Which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 8)} {(0, 0), (1, 2), (2, 6), (2, 8)} {(0, 0), (0, 2), (2, 0), (2, 4)} {(0, 2), (1, 4), (2, 6), (3, 6)}
Answer: {(0, 2), (1, 4), (2, 6), (3, 6)}
Step-by-step explanation:
For a relation to be considered a function, each x-value needs to have one corresponding y-value--it cannot have more than 1.
Since all the other sets of ordered pairs feature points with two x-values with different y-values, the set above is the only function of the provided options.

12,17,24,33,44,57,72 what is the nth term
Answer: 57
Step-by-step explanation:
Answer:
89
Step-by-step explanation:
Every term is +2
Starting with 12 to 17, you added 5. Then 17 and 7 to get 24. Then 24 and 9 to get 33, etc. You`ll notice that the bolded terms add by two. The systems continues just like that. You need to add 17 to 72, which gives you 89 as the 9th term. Hope this helps
