Lines m and n are parallel, as shown in the diagram below. What are the measures of angles A and B?
Answer:
a = 55° and b = 60°
Step-by-step explanation:
→ Remember 2 key points about angles
Angles in a triangle add up to 180°Alternate angles are equal→ Angle a is alternate to 55° so using the 2nd point,
a = 55°
→ Remember the fact that angle in a triangle add up to 180°
55° + 65° + b = 180°
→ Collect the whole numbers
120° + b = 180°
→ Minus 120° from both sides to isolate b
b = 60°
The solution is : the measures of angles A and B are:
A = 55° and B = 60°
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
We know that 55+ b+ other angle = 180 since they make a straight line
The other angle = 65 since they are alternate interior angles
55+ B+ 65 = 180
Combine like terms
120 + B = 180
B = 60
A + B + 65 = 180
interior angles of a triangle must equal 180 degrees
A +60+ 65 =180
Combine like terms
A +125 = 180
A = 55
Hence, The solution is : the measures of angles A and B are:
A = 55° and B = 60°

The graph of g(x) resembles the graph of f(x)=x^2, but it has been changed. Which of these is the equation of g(x)?
Answer:
A.
Step-by-step explanation:
We need to find the equation where, if x is equal to 3, g(x) is equal to 1, because g(x) passes through the point (3,1)
Then, replacing x by 3 on every option we get:
[tex]g(x)=(\frac{1}{3}x)^2= (\frac{1}{3}3)^2=1\\g(x)=(\frac{1}{9}x)^2= (\frac{1}{9}3)^2=\frac{1}{9}\\g(x)= \frac{1}{3}x^2= \frac{1}{3}3^2=3\\g(x)=3x^2=3*3^2=27[/tex]
So, the answer is A. because g(x) is equal to 1
Consider the y-intercepts of the functions:
f(x) = |x – 1] + 2
g(x) =
(x + 3)
h(x) = (x + 1) -3
1
What is the ordered pair location of the greatest y-intercept of the three functions?
Answer:
+3, 0
Step-by-step explanation:
y-intercept for f(x) is when x = 0, so it is +1, 0
y-intercept for g(x) is when x = 0, so it is +3, 0
y-intercept for h(x) is when x = 0, so it is -2, 0
The y-intercept of a function is the point where x = 0.
The ordered pair that represents the greatest y-intercept is (0,3)
The functions are given as:
[tex]\mathbf{f(x) = |x - 1| + 2}[/tex]
[tex]\mathbf{g(x) = (x + 3)}[/tex]
[tex]\mathbf{h(x) = (x + 1) - 3}[/tex]
Set x = 0, and solve the functions
[tex]\mathbf{f(x) = |x - 1| + 2}[/tex]
Substitute 0 for x
[tex]\mathbf{f(0) = |0 - 1| + 2}[/tex]
[tex]\mathbf{f(0) = |- 1| + 2}[/tex]
Remove absolute brackets
[tex]\mathbf{f(0) = 1 + 2}[/tex]
[tex]\mathbf{f(0) = 3}[/tex]
[tex]\mathbf{g(x) = (x + 3)}[/tex]
Substitute 0 for x
[tex]\mathbf{g(0) = (0 + 3)}[/tex]
[tex]\mathbf{g(0) = 3}[/tex]
[tex]\mathbf{h(x) = (x + 1) - 3}[/tex]
Substitute 0 for x
[tex]\mathbf{h(0) = (0 + 1) - 3}[/tex]
[tex]\mathbf{h(0) = 1 - 3}[/tex]
[tex]\mathbf{h(0) = - 2}[/tex]
Hence, the ordered pair that represents the greatest y-intercept is (0,3)

If f(x)=k (square root)2+x, and f^-^1 (-15)=7, what is the value of k
There's a bit of ambiguity in your question...
We know that [tex]f^{-1}(-15)=7[/tex], which means [tex]f(7)=-15[/tex].
I see three possible interpretations:
• If [tex]f(x)=k\sqrt2+x[/tex], then
[tex]f(7)=-15=k\sqrt2+7\implies k\sqrt2=-22\implies k=-\dfrac{22}{\sqrt2}=11\sqrt2[/tex]
• If [tex]f(x)=k\sqrt{2+x}[/tex], then
[tex]f(7)=-15=k\sqrt{2+7}\implies -15=3k\implies k=-5[/tex]
• If [tex]f(x)=\sqrt[k]{2+x}[/tex], then
[tex]f(7)=-15=\sqrt[k]{2+7}\implies-15=9^{1/k}\implies\dfrac1k=\log_9(-15)[/tex]
which has no real-valued solution.
I suspect the second interpretation is what you meant to write.

If Ahmed scored 45% in a test and the maximum mark was 60, what was his mark for the test?
Answer: 27
Step-by-step explanation:
45% is equal to .45.
.45 x 60 = 27.
If we multiply .45 by 60, we get 27. Therefore, Ahmed got 27 marks out 60.
If you want to check your answer, you can divide 27/60 to get .45.
Answer:
[tex]\boxed{27 \ Marks}[/tex]
Step-by-step explanation:
Total Marks = 60
Ahmed Scored in the test = 45% of 60
=> [tex]\frac{45}{100} * 60[/tex]
=> [tex]\frac{45}{10} * 6[/tex]
=> 4.5 * 6

3. Consider the sequence,-8, -5, -2, 1, ...
a) Determine the explicit formula for the general term, 1,, of this sequence in simplified
form. (2 marks)
b) Use this formula to determine the value of t20. (1 mark)
c) Algebraically determine which term has a value of 40. (1 mark)
Answer:
a) [tex]a_n=3\,n-11[/tex]
b) [tex]a_{20}=49[/tex]
c) term number 17 is the one that gives a value of 40
Step-by-step explanation:
a)
The sequence seems to be arithmetic, and with common difference d = 3.
Notice that when you add 3 units to the first term (-80, you get :
-8 + 3 = -5
and then -5 + 3 = -2 which is the third term.
Then, we can use the general form for the nth term of an arithmetic sequence to find its simplified form:
[tex]a_n=a_1+(n-1)\,d[/tex]
That in our case would give:
[tex]a_n=-8+(n-1)\,(3)\\a_n=-8+3\,n-3\\a_n=3n-11[/tex]
b)
Therefore, the term number 20 can be calculated from it:
[tex]a_{20}=3\,(20)-11=60-11=49[/tex]
c) in order to find which term renders 20, we use the general form we found in step a):
[tex]a_n=3\,n-11\\40=3\,n-11\\40+11=3\,n\\51=3\,n\\n=\frac{51}{3} =17[/tex]
so term number 17 is the one that renders a value of 40

Consider the points P(5,5,1) and Q(13,13,3).
a. Find PQ with right arrow and state your answer in two forms: (a,b,c) and ai+bj+ck.
b. Find the magnitude of PQ with right arrow.
c. Find two unit vectors parallel to PQ with right arrow.
Answer:
a) [tex]\overrightarrow{PQ} = (8,8, 2)[/tex] or [tex]\overrightarrow{PQ} = 8\,i + 8\,j + 2\,k[/tex], b) The magnitude of segment PQ is approximately 11.489, c) The two unit vectors associated to PQ are, respectively: [tex]\vec v_{1} = (0.696,0.696, 0.174)[/tex] and [tex]\vec v_{2} = (-0.696,-0.696, -0.174)[/tex]
Step-by-step explanation:
a) The vectorial form of segment PQ is determined as follows:
[tex]\overrightarrow {PQ} = \vec Q - \vec P[/tex]
Where [tex]\vec Q[/tex] and [tex]\vec P[/tex] are the respective locations of points Q and P with respect to origin. If [tex]\vec Q = (13,13,3)[/tex] and [tex]\vec P = (5,5,1)[/tex], then:
[tex]\overrightarrow{PQ} = (13,13,3)-(5,5,1)[/tex]
[tex]\overrightarrow {PQ} = (13-5, 13-5, 3 - 1)[/tex]
[tex]\overrightarrow{PQ} = (8,8, 2)[/tex]
Another form of the previous solution is [tex]\overrightarrow{PQ} = 8\,i + 8\,j + 2\,k[/tex].
b) The magnitude of the segment PQ is determined with the help of Pythagorean Theorem in terms of rectangular components:
[tex]\|\overrightarrow{PQ}\| =\sqrt{PQ_{x}^{2}+PQ_{y}^{2}+PQ_{z}^{2}}[/tex]
[tex]\|\overrightarrow{PQ}\| = \sqrt{8^{2}+8^{2}+2^{2}}[/tex]
[tex]\|\overrightarrow{PQ}\|\approx 11.489[/tex]
The magnitude of segment PQ is approximately 11.489.
c) There are two unit vectors associated to PQ, one parallel and another antiparallel. That is:
[tex]\vec v_{1} = \vec u_{PQ}[/tex] (parallel) and [tex]\vec v_{2} = -\vec u_{PQ}[/tex] (antiparallel)
The unit vector is defined by the following equation:
[tex]\vec u_{PQ} = \frac{\overrightarrow{PQ}}{\|\overrightarrow{PQ}\|}[/tex]
Given that [tex]\overrightarrow{PQ} = (8,8, 2)[/tex] and [tex]\|\overrightarrow{PQ}\|\approx 11.489[/tex], the unit vector is:
[tex]\vec u_{PQ} = \frac{(8,8,2)}{11.489}[/tex]
[tex]\vec u_{PQ} = \left(\frac{8}{11.489},\frac{8}{11,489},\frac{2}{11.489} \right)[/tex]
[tex]\vec u_{PQ} = \left(0.696, 0.696,0.174\right)[/tex]
The two unit vectors associated to PQ are, respectively:
[tex]\vec v_{1} = (0.696,0.696, 0.174)[/tex] and [tex]\vec v_{2} = (-0.696,-0.696, -0.174)[/tex]

Match the system with the amounts of solutions. pls
From top to bottom, the answers are
no solutionsone solutioninfinitely many solutionsone solution==============================================
Explanation:
The first system of equations has each equation with the same slope 2, but different y intercepts. This indicates we have parallel lines. Parallel lines never cross, so there are no solutions. A solution is where the two lines cross.
The second system of equation has one solution where the two lines cross. This is because the slopes are different
The third system has infinitely many solutions. We have the same line graphed out twice. One line is directly on top of the other to yield infinitely many intersection points.
The fourth system is similar to the second system. Different slopes lead to exactly one solution. The y intercept doesn't affect the number of solutions (whether its 0, 1 or infinitely many)
For each equation shown, they are in the form y = mx+b with m as the slope and b as the y intercept.
Bus A and Bus B leave the bus depot at 7 am. Bus A takes 25 minutes to do its route and bus B takes 40 minutes to complete its route. At what time are they both back at the bus depot together? Give your answer as a 12-hour clock time.
====================================================
Explanation:
List out the multiples of 25 to get {25, 50, 75, 100, 125, 150, 175, 200}
Do the same for the multiples of 40 to get {40, 80, 120, 160, 200}
We see that the lowest common multiple (LCM) is 200
---------
Another way to get the LCM is to multiply 25 and 40 to get 25*40 = 1000. Then divide this over 5 as this is the GCF between the two original numbers. We end up with the same LCM since 1000/5 = 200.
--------
There's a third way to get the LCM
List out the prime factorization of each value
25 = 5*5
40 = 2*3*5
Note how we have the unique factors of 2, 3 and 5. Circle the unique factors such that we highlight the ones that occur the most. We have 2 occur once, 3 occur once, and 5 occurs twice. We have circled one 2, one 3, and two 5's. They multiply out to 2*3*5*5 = 8*25 = 200
-----------------
Whichever method works for you, the LCM is 200. This means that every 200 minutes, we have bus A and bus B arrive at the depot at the same time. Their cycles line up at the 200 minute mark.
Convert this to hours,minutes format.
200 minutes = 180 minutes + 20 minutes
200 minutes = 3 hours + 20 minutes
200 minutes = 3 hrs, 20 min
We can represent "3 hrs, 20 min" in 12-hour clock notation by writing 3:20
Add this onto 7:00, which is 7 AM and we get
(7:00) + (3:20) = (7+3):(00+20) = 10:20 AM
We have started at 7 AM and fast forwarded 3 hours and 20 minutes to arrive at 10:20 AM.
