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

×2 , -2

Step-by-step explanation:

3×2= 6

6-2=4

4×2=8

8-2 =6

Answer:

x2, -2

Step-by-step explanation:

To figure out this problem, try applying the answers to the numbers already placed.

As seen in the sequence, First you multiply the number by two and therefore get the second number. Then you take that number and subtract two in order to find the next value, You repeat this process in order to find infinite values of the sequence.

Answer:

A). Yes

B). Yes

C). No

D). Yes

Step-by-step explanation:

Coordinates of the midpoint of a segment joining two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] are given by [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex].

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]

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.

The answer is C

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

∵ 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

Answer:

8) d

9) a

Step-by-step explanation:

8) C = d ·π

36 = d ·π

36 / π = d

9) 4π is the difference, which is 12.56

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.

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]

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

Step-by-step explanation:

The feasible region of the result is defined by the system of inequalities.

Correct response:

The system of inequalities shown in the graph is given by the option B.

B. y ≤ x + 1

y ≤ x² - 3·x

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

Methods used to find the system of inequalities

Please find attached the possible graph of the inequality

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

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
