The lines represented by the equations 25y- 20x=100 and 5y - 4x = 20 are
Answers
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

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.
Answers
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.

7. In a right angles triangle if an angle measures 35º, then find the
measure of the third angle.
Answers
Answer:
55°
Step-by-step explanation:
A right angle is = to 90°
90° + 35° = 125°
Angles in a triangle add up to 180
180 - 125 = 55
Answer:
The answer is 55
Step-by-step explanation:
If all the angles of a triangle add up to 180°, and one of the angles are 35° and another is obviously 90° that means you have to add up the two angles, then subtract that answer from 180°
90 + 35 = 125
180 - 125 = 55

Hard qn on Trigonometric equations and identities, please help
Answers
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.
