B. 0.36
Step-by-step explanation:
Given:
Right ∆ABC,
AB = 5
BC = 13.93
CA = 13
Required:
Value of sin C
SOLUTION:
[tex] sin(C) = \frac{opposite}{hypotenuse} [/tex]
Opposite = 5
Hypotenuse = 13.93
[tex] sin(C) = \frac{5}{13.93} [/tex]
[tex] sin(C) = 0.3589 [/tex]
[tex] sin(C) = 0.36 [/tex]
the answer would be B, 0.36

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.) midpoint (8,5), endpoint (10,8)
Answers
Step-by-step explanation:
Hey, there!!
Here, one point is A(10,8) and P(8,5) is the midpoint.
Let B(x,y) be the another end point.
Now,
Using midpoint formulae,
[tex]p(x.y) = \frac{x1 + x2}{2} . \frac{y1 + y2}{2} [/tex]
[tex]p(8.5) = ( \frac{10 + x}{2} . \frac{8 + y}{2} )[/tex]
Since they are equal,equating with their corresponding elements we get,
[tex]8 = \frac{10 + x}{2} [/tex]
or, 16 = 10 + x
or, x=16-10
Therefore, x = 6
Now,
[tex]5 = \frac{8 + y}{2} [/tex]
or, 10 = 8 + y
or, y = 2
Therefore, The coordinates of another point are B(6,2)

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Step 1: Find 2 coordinates
(50, 20)

m = (50 - 20)/(70 - 50)
m = 30/20
m = 3/2
Answer:
3/2
Step-by-step explanation:
To find the slope, pick two points on the line, and use the slope formula
( 50,20) and (90,80)
m = ( y2-y1)/(x2-x1)
= (80-20)/(90-50)

Two functions represent the composite function h(x) = (x – 1)³ + 10 so that h(x) = (g compose f)(x). Given f(x) = x + a and g(x) = x³ + b, what values of a and b would make the composition true?
Answers
Answer:
a = -1, b = 10Step-by-step explanation:
Given the function h(x) = (x – 1)³ + 10 so that h(x) = (g°f)(x). If f(x) = x + a and g(x) = x³ + b, then;
g(f(X)) = g(x+a).
To get g(x+a), we will have to replace the variable x with x+a in g(x) as shown;
g(x+a) = (x+a)³ + b
g(f(x)) = (x+a)³ + b
Since h(x)= g(f(x)) = (x – 1)³ + 10
g(f(x)) = (x+a)³ + b = (x – 1)³ + 10
Hence (x+a)³ + b = (x – 1)³ + 10
On comparing the coefficients to get the value of a and b;
(x+a)³ = (x-1)³
Take the cube root of both sides
∛(x+a)³ = ∛(x-1)³
x+a = x-1
x+a-x = -1
a = -1
Also on comparing, b = 10
Hence the values of a and b would make the composition true are -1 and 10 respectively.
Answer:
a: -1
b: 10

Answers
Answer:
Step-by-step explanation:
Answer:
(A) A translation one unit to the left followed by a 180-degree rotation.
Step-by-step explanation:
I figured this out by seeing that ABCD was one unit too far from the x=0 line than A’B’C’D. To get it the same distance, we move it left one, which is the same as transforming one unit to the left.
Now, we can see that the coordinates are opposite of each other - this signifies a 180° rotation around the origin.
So, it’s a transformation one unit to the left and a 180° rotation around the origin.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month.

Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
Answers
Answer:
y = (-2/3)x + 490
Step-by-step explanation:
Our given equation is 2x + 3y = 1,470.
First subtract 2x from both sides of the equation:
3y = 1470 - 2x
Next divide both sides by 3:
y = 490 - (2/3)x
Move the terms on the right to fit the slope-intercept form (y = mx + b):
y = (-2/3)x + 490
Answer:
2x + 3y = 1470
=> 3y = 1470 -2x
=> y = 1470/3 - 2/3x
=> y = -2/3x + 490
First, I made the 3y alone by subtracting 2x to both sides.
Next, I divided 3 from both sides to make y alone.
Lastly, I got the slope-intercept form.
Slope = the number with which "x" is multiplied.
So, In this equation slope = -2/3
Y-intercept can be found my making the x as 0
=> y = -2/3(0) + 490
=> y = 490
So, the y-intercept is (0,490)
X-Intercept can be found by making y as 0
=> 0 = -2/3x + 490
=> -490 = -2/3x
=> -490 * 3 = -2x
=> -1470 = -2x
=> -1470/2 = -x
=> -735 = -x
=> x = 735
So, x-intercept = (735,0)

Answers
Answer: 30 students in the class.
Step-by-step explanation:
Domain is the set of all input values.
Given : A teacher writes a function to model the rate of completion on a test .
C(n) represents the completion rate
n represents the number of students who have completed the test over a class period.
Here , input variable = n
So, Domain= set of values for n
Since class has 30 students.
So, Domain = 30 students.
Hence, the appropriate domain of the function : 30 students.

in triangle ABC, angle b = 45 degree, angle c =55 degree,AD bisects angle A,find angle ADB and Angle ADC
Answers
Answer:
angle a + angle b + angle c = 180 (angle sum property)
a + 45+55= 180
a + 100 = 180
a = 180-100
a= 80
AD bisects angle a
i.e angle ADB= angle ADC
angle ADB + angle ADC = 80
angle ADB + angle ADB =80
2angleADB= 80
angle ADB = 80/2
angle ADB = 40
angle ADB = angle ADC
40 = angle ADC

Answers
Answer:
The correct option is;
Angle A and B are congruent
Step-by-step explanation:
The given parameters are;
Quadrilateral ABCD = Parallelogram
Side AB is parallel to CD
Therefore, we have for properties of a parallelogram
Opposite sides are parallel
Therefore, AB and CD are opposite sides
Opposite sides are congruent
Opposite angles are congruent, therefore ∠A and ∠C are congruent and ∠B and ∠D are congruent (depending on the orientation of side CD)
Consecutive angles are supplementary, therefore, ∠A and ∠B are supplementary angles and ∠C and ∠D are supplementary angles
Therefore, the statement which is false is Angle ∠A and ∠B are congruent.

in a small town 68% of the people owned television 72% on radio and 12% owned neither television nor radio (1)represent the information on a Veen diagram.
(2)what percentage of the population owned television.
Answers
Answer:
Percentage of those who owned TV is 16%
Step-by-step explanation:
Given
n(TV) = 68%
n(Radio) = 72%
None = 12%
Total Population = 100%
Required
What percentage owned television
See attachment for Venn diagram
[Calculating the percentage that owned television]
Represent those that own TV and Radio with x
So:
n(Both) = x
From the Venn diagram;
Total Population = (n(TV) - x )+ (n(Radio) - x) + None + x
This gives
100% = (68% - x) + (72% - x) + 12% + x
Open all brackets
100% = 68% - x + 72% - x + 12% + x
Collect like terms
100% = 68% + 72% + 12% - x - x + x
100% = 152% - x
Make x the subject of formula
x = 152% - 100%
x = 52%
The percentage of those who owned TV = n(TV) - x
Percentage = 68% - 52%
Percentage = 16%
