Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15
Which of the sets of ordered pairs represents a function?
A = {(-5,5), (-2, 2), (2,-2), (5, -5)}
B = {(4, 2), (3, -2), (9, 4), (11, -3)}
help!! whats the answer? and how do I solve!! :(

Express as a simple fraction in lowest terms
OK
Answer:
1/3
Step-by-step explanation:
First find the LCD or least common denominator. The least common denominator is the number that both of the denominators are divisible by.
In this case, 2 and 3 are both divisible by 6.
Convert both fractions into a fraction with a denominator of 6.
1/2 = 3/6 (multiply numerator and denominator by 3)
2/3 = 4/6 (multiply numerator and denominator by 2)
Now you can multiply as they have the same denominator.
3/6 × 4/6 = 12/36
Simplify.
12/36 = 1/3 (numerator and denominator are divisible by 12)
Hope that helps.

50 points! Tell whether the orthocenter is inside, on, or outside the triangle. Then find the coordinates of the orthocenter.
Q(-1, 5), R(4, 3), S(-1, -2)
Answer:
(1,3) is inside the triangleStep-by-step explanation:
Orthocenter is the intersection of altitudes.
We'll calculate the slopes of the two sides and their altitudes ad find the intersection.
Side QRm = (3 - 5)/(4 - (-1)) = -2/5Perpendicular slope:
-1/m = 5/2Perpendicular line passes through S(-1, -2):
y - (-2) = 5/2(x - (-1)) ⇒ y = 5/2x + 1/2Side RSm = (-2 - 3)/(-1 -4) = -5/-5 = 1Perpendicular slope:
-1/m = -1/1 = -1Perpendicular line passes through Q(-1, 5):
y - 5 = -(x - (-1)) ⇒ y = -x + 4The intersection of the two lines is the orthocenter.
Solve the system of equations to get the coordinates of the orthocenter:
5/2x + 1/2 = x + 45x + 1 = -2x + 87x = 7x = 1Find y-coordinate:
y = -1 + 4 = 3The orthocenter is (1, 3)
If we plot the points, we'll see it is inside the triangle
find the 50ty term if the nth term is 5n-3
Answer:
247
Step-by-step explanation:
From the question given above, the following data were obtained:
nth term (Tₙ) = 5n – 3
Number of term (n) = 50
50th term (T₅₀) =?
The 50th term can be obtained as follow:
Tₙ = 5n – 3
T₅₀ = 5(50) – 3
T₅₀ = 250 – 3
T₅₀ = 247
Therefore, the 50th term is 247.

Step-by-step explanation:
What is the common difference (d) of the A.P. 7, 1, – 5, – 11, ... ?
Answer:
d = -6
Step-by-step explanation:
t1 = 7, t2 = 1, t3 = -5, t4 = -11
t2 - t1 = 1 - 7 = -6
t3 - t2 = -5 - 1 = -6
t4 - t3 = - 11 - (- 5) = -11 + 5 = -6
Therefore, the common difference is constant( I. e -6). Therefore the common difference is -6.

The graph of a linear function is shown on the grid.
What is the slope of the line?
- 10
3
0
NW
D 2
Answer:
The slope is -2/3
Step-by-step explanation:
Pick two points on the graph and use the slope formula.
For example, (2, 0) and (-1, 2) are on the graph.
m = change in y/change in x
= (2 - 0)/(-1 - 2)
= 2/-3
The slope is -2/3

Create a graph of the combined function h(x) = f(x) / g(x) in which f(x) = x - 6 and g(x) = x + 6. On your graph, show the graphs of f(x) and g(x) also.
Answer:
we have
f(x)=x-6f(x)=x−6 -----> equation A
This is a linear equation with slope m=1m=1 and a y-intercept equal to -6−6
g(x)=x+6g(x)=x+6 -----> equation B
This is a linear equation with slope m=1m=1 and a y-intercept equal to 66
The function f(x) and g(x) are parallel lines
we know that
h(x)=f(x)+g(x)h(x)=f(x)+g(x)
Substitute
h(x)=x-6+x+6h(x)=x−6+x+6
h(x)=2xh(x)=2x
This is a linear equation with slope m=2m=2 that passes through the origin ( represent a direct variation)

Answer:
fourth option
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
= [tex]\frac{15+16+21+23+25+25+25+39}{8}[/tex]
= [tex]\frac{189}{8}[/tex]
= 23.6 ( to 1 dec. place )
The median is the middle value of the data set. If there is no exact middle then it is the average of the values either side of the middle.
15 16 21 23 25 25 25 39
↑ middle
median = [tex]\frac{23+25}{2}[/tex] = [tex]\frac{48}{2}[/tex] = 24
The mode is the value that occurs most often, that is 25
Thus
mean = 23.6 , median = 24 , mode = 25

Find the missing angle measure of the triangle.
Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2

Answer:
opposite sides of parallelogram are parellel.
so, angle A and angle D are co interior angle.
(3x+4)°+x°=180°
