I took the quiz
The vertices of ABC are A (-5, 5), B (-2,5), C(-2,3).
1. Graph the figure ABC.
2, Translate each vertex 3 units down and 4 units to left.
3. Draw and label the vertices A'B'C.
Answer:
It will be in the attachment below.
Step-by-step explanation:
Translating a vertex 3 units down and 4 units to the left means that the x coordinate is 4 less than before and the y is 3 less. So, subtract 4 from -5 to get -9; from -2 (twice) to get -6 (twice), and subtract 3 from 5 (twice) to get 2 (twice); from 3 to get 0. So, the new coordinates are (-9, 2), (-6, 2), and (-6, 0). The original shape is in red, and the translated shape is blue.
Write the slope-intercept form of an equation of the line that passes through the point (5, -5) and is parallel to the graph of the equation 3x + y = -2.
Answer:
[tex]y=-3x+10[/tex]
Step-by-step explanation:
Parallel equations have same slope
Therefore slope of 3x + y = -2 is same as slope of other equation.
Slope of 3x + y = -2 is
m=-3
Now we have write equation having slope -3 and passing through point (5, -5)
[tex](y+5)=-3(x-5)[/tex]
[tex]y=-3x+10[/tex]
Mrs. K has 23 students in her class. Mr. Curran has 19 in his class.
How many more students does Mrs. K have than Mr. Curran?
Answer:
4 more students
Step-by-step explanation:
To find how many more students Mrs. K has, subtract 19 from 23:
23 - 19
= 4
So, Mrs. K has 4 more students than Mr. Curran

The possible graph obtained from a similar question has a straight line portion and a quadratic portion.
Points on the straight line are; (0, 1), (3, 4), and (5, 6)
Therefore;
Equation of the line is; y - 1 = 1 × x
Therefore;
y = x + 1
The shaded region is below the line which gives;
y ≤ x + 1
Points on the quadratic graph are; (0, 0), (4, 4), and (2, -2).
The general form of a quadratic equation is; y = a·x² + b·x + c
Therefore, we have;
0 = a × 0 + b × 0 + c
Which gives;
c = 0
4 = a × 4² + b × 4 = 16·a + 4·b
-2 = a × 2² + b × 2 = 4·a + 2·b
4 = 16·a + 4·b...(1)
-2 = 4·a + 2·b...(2)
Multiplying equation (2) by 2 and subtracting from equation (1) gives;
2 × -2 = 2 × (4·a + 2·b) = 8·a + 4·b
-4 = 8·a + 4·b
4 - (-4) = 16·a + 4·b - (8·a + 4·b) = 8·a
8 = 8·a
a = 1
-2 = 4 × 1 + 2·b
2·b = -2 - 4 = -6
Which gives;
y = 1·x² - 3·x = x² - 3·x
The line is a solid line and shaded region is the region under the graph which gives;
y ≤ x² - 3·x
Therefore;
The inequalities in the graph are given by option B.
B. y ≤ x + 1
y ≤ x² - 3·x

The function f(x) is a quadratic function and the zeros of f(x) are -2 and 6. Assume the leading coefficient of f(x) is 1. Write the equation of the quadratic polynomial in standard form.
Step-by-step explanation:
Since the zeroes of f(x) are -2 and 6,
(x + 2) and (x - 6) are factors of f(x).
=> f(x) = (x + 2)(x - 6) = x² - 4x - 12.
Answer:
The function f(x) is a quadratic function and the zeros of f(x) are -2 and 6. Assume the leading coefficient of f(x) is 1.
(x+2) and (x-6) are the factors of f(x)
[tex]f(x) = (x + 2)(x - 6) \\ = {x}^{2} - 6x + 2x - 12 \\ = \boxed{{x}^{2} - 4x - 12}[/tex]
(x²-4x-12) is the right answer.Hard qn on Trigonometric equations and identities, please help
Answer:
(i) [tex]OE = 0.6\cdot \sin \theta + 1.4\cdot \cos \theta[/tex], (ii) [tex]\theta \approx 33.368^{\circ}[/tex], (iii) The maximum value of OE is approximately 1.523 meters, which is associated with an angle of approximately 23.199º.
Step-by-step explanation:
(i) From Geometry, we get that sum of internal angles of trangle AOD.
[tex]\angle A + \angle O + \angle D = 180^{\circ}[/tex] (1)
If we know that [tex]\angle O = 90^{\circ}[/tex] and [tex]\angle A = \theta[/tex], then the value of [tex]\angle D[/tex] is:
[tex]\angle D = 180^{\circ}-90^{\circ}-\theta[/tex]
[tex]\angle D = 90^{\circ}-\theta[/tex] (2)
But we also have the following identity:
[tex]\angle D +\angle D' +\angle D'' = 180^{\circ}[/tex] (3)
If we know that [tex]\angle D = 90^{\circ}-\theta[/tex] and [tex]\angle D' = 90^{\circ}[/tex], then the value of [tex]\angle D''[/tex] is:
[tex]90^{\circ}-\theta +90^{\circ}+\angle D'' = 180^{\circ}[/tex]
[tex]\angle D'' = \theta[/tex] (4)
By Trigonometry, we derive the following formula:
[tex]OE = OD +DE[/tex]
[tex]OE = AD\cdot \sin A +CD\cdot \cos D''[/tex] (5)
If we know that [tex]AD = 0.6\,m[/tex], [tex]CD = 1.4\,m[/tex], [tex]A = \theta[/tex] and [tex]D'' = \theta[/tex], then the value of OE is:
[tex]OE = 0.6\sin \theta + 1.4\cos \theta[/tex] (6)
(ii) If we know that [tex]OE = 1.1\,m[/tex], then the value of [tex]\theta[/tex]:
[tex]0.6\cdot \sin \theta + 1.4\cdot \cos \theta = 1.1[/tex]
By trial and error, we find that [tex]\theta \approx 33.368^{\circ}[/tex].
(iii) Let [tex]OE = 0.6\cdot \sin \theta + 1.4\cdot \cos \theta[/tex], the first and second derivatives of the function are, respectively:
[tex]OE' = 0.6\cdot \cos \theta -1.4\cdot \sin \theta[/tex] (7)
[tex]OE'' = -0.6\cdot \sin \theta -1.4\cdot \cos \theta[/tex] (8)
We equalize the first derivative of the function to zero and solve for [tex]\theta[/tex]:
[tex]0.6\cdot \cos \theta - 1.4\cdot \sin \theta = 0[/tex]
[tex]1.4\cdot \sin \theta = 0.6\cdot \cos \theta[/tex]
[tex]\tan \theta = \frac{0.6}{1.4}[/tex]
[tex]\theta \approx \tan^{-1} \frac{0.6}{1.4}[/tex]
[tex]\theta \approx 23.199^{\circ}[/tex]
And we evaluate the second derivative:
[tex]OE'' = -0.6\cdot \sin 23.199^{\circ}-1.4\cdot \cos 23.199^{\circ }[/tex]
[tex]OE'' = -1.523[/tex]
Then, the critical value is associated with an absolute maximum.
The maximum value of OE is:
[tex]OE = 0.6\cdot \sin 23.199^{\circ}+1.4\cdot \cos 23.199^{\circ }[/tex]
[tex]OE \approx 1.523\,m[/tex]
The maximum value of OE is approximately 1.523 meters, which is associated with an angle of approximately 23.199º.

What is the nth term rule of the linear sequence below?
7, 9, 11, 13, 15, ...
Tn = 0
Answer:
the best number is 17 cuz the sequence is to add 2 sooo it's 17 then 19
Answer:
2n+5
Step-by-step explanation:
Sequence = 7,9,11,13,15 ....
tn = a + (n-1)d where a is first number, and d is common difference
tn = 7 + (n-1)2
= 7 + 2n - 2
= 2n+5
therefore tn (or nth term rule) = 2n+5

The lines represented by the equations 25y- 20x=100 and 5y - 4x = 20 are
Answer:
The system of equations represent the same line ⇒ B
Step-by-step explanation:
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system of the equations represent the same linea = d, b = e, and c ≠ f, then the system of the equations represent two parallel linesa ≠ d, and/or b ≠ e, and/or c ≠ f, then the system of the equations represent two intersecting lines∵ The one line represented by the equation 25y - 20x = 100
→ Divide the terms of the equation by 5 to simplify it
∴ 5y - 4x = 20 ⇒ (1)
∴ a = 5, b = -4, c = 20
∵ The other line represented by the equation 5y - 4x = 20 ⇒ (2)
∴ d = 5, e = -4, f = 20
→ Compare the two equations
∵ a = d, b = e, c = f
→ By using the 1st case above
∴ The system of equations represent the same line

a man bought a camera for rupees 460 and sold it at 5% profit find the selling price of the camera
Answer:
profit is 23 selling price is $483
Step-by-step explanation:
Cp of Camera=Rs.460
profit= 5%
so profit =5% of 460=(5*460)/100=Rs.23
then selling prices of camera= cp of camera + profit Rs=$460+23=483 hope this helps
