Answer:

The image of [tex]P(x,y) = (2,-3)[/tex] is [tex]P'(x,y) = (-2, -3)[/tex].

Step-by-step explanation:

According to this statement, we need to find the image of a given point by reflection with respect to the y-axis. The reflection can be done by following operation:

[tex]P(x,y) = (x, y) \to P'(x,y) = (-x, y)[/tex] (1)

Where:

[tex]P(x,y)[/tex] - Original point.

[tex]P'(x,y)[/tex] - Reflected point.

If we know that [tex]x = 2[/tex] and [tex]y = -3[/tex], then the reflecting point is:

[tex]P'(x,y) = (-2, -3)[/tex]

The image of [tex]P(x,y) = (2,-3)[/tex] is [tex]P'(x,y) = (-2, -3)[/tex].

Answer:

x = - 4

Step-by-step explanation:

Since we are looking at a circle, we know that the sum of all arc angles should add up to 360°. This means that the following...

- 32x - 3 = 360 - 85 - 35 - 115

- 32x - 3 = 125

- 32x = 125 + 3

- 32x = 128

x = 128 / (-32)

x = - 4

Answer:

add the two bases together: 19.5 + 14.5 = 34 x 8 (height) = 272 divided by 2 (times half) = 136cm is your answer.

Formula of a trapezoid:

Base 1 + Base 2 times height times height (basically dividing by 2)

the answer is seven twelfth

Answer:

Step-by-step

sum of the adjacent angles of parallelogram is supplementary.

Therefore,

Q + R = 180°

4y+7 + 10y-37 = 180°

14y - 30° = 180°

14y = 210°

y = 210°/14

y = 15°

Step-by-step explanation:

8x + 12 = 52

move constant to right

8x=52-12

subtract numbers

8x=40

divide both sides

The discriminant of function [tex]f(x,y)=x^3 + y^4 - 6x-2y^2+3[/tex] is 72xy³ – 24x and points (√2,0), (-√2, 1) and (-√2, -1) are saddle point, and points (√2, 1) and (√2, -1) are local minima.

A function is an expression in terms of one or more variable.

If f(x, y)  is a two-dimensional function that has a local extremum at a point ([tex]x_o, y_o[/tex])  and has continuous partial derivatives at this point, then [tex]f_x (x_o, y_o)=0[/tex] and [tex]f_y (x_o, y_o)=0[/tex]. The second partial derivatives test classifies the point as a local maximum or local minimum.

Then

1. If D > 0 and [tex]f_{xx}(x_o, y_o) > 0[/tex] , the point is a local minimum.

2. If D > 0 and [tex]f_x_x (x_o, y_o) < 0[/tex], the point is a local maximum.

3. If D < 0, the point is a saddle point.

4. If D = 0, higher order tests must be used.

Given that

[tex]f(x,y)=x^3 + y^4 - 6x-2y^2+3[/tex]

[tex]f_x = 3x^2-6[/tex]

[tex]f_x = 0[/tex] implies that [tex]x = \pm\sqrt2[/tex]

[tex]f_y= 4y^3-4y[/tex]

[tex]f_y= 0[/tex]  implies that y = 0; y = [tex]\pm[/tex]1.

Thus, the critical points are (√2,0), (√2,1), (√2, -1);(-√2,0), (-√2,1); (√2, -1).

[tex]f_{xx} = 6x[/tex]; [tex]f_y_y = 12y^3 - 4[/tex], [tex]f_{xy}= 0[/tex]

D(x, y) = [tex]f_{xx}f_{yy} - f_{xy}^2[/tex]

          = 6x × (12y³ – 4)

D(√2, 0) = -24√2 < 0  implies (√2,0)  is a saddle point.

D(√2, 1) = 48√2 > 0 ; [tex]f_{xx}(2, 1) = 6\sqrt2 > 0[/tex] implies (√2, 1)  is local minimum.

D(√2, -1) = 48√2 > 0; [tex]f_{xx}(2, -1) = 6\sqrt2 > 0[/tex]  implies (√2, -1)  is local minimum.

D(-√2, 0) = 24√2 > 0; [tex]f_{xx}(-2,0) = -6\sqrt2 < 0[/tex]  implies (-√2, 0)  is local maximum.

D(-√2, 1) = -48√2 < 0  implies (-√2, 1)  is a saddle point.

D(-√2, -1) = -48√2 < 0  implies (-√2, -1)  is a saddle point.

Thus, (√2,0), (-√2, 1) and (-√2, -1) are saddle point, and (√2, 1) and (√2, -1) are local minima.

Answer: Rs. 11,520

Step-by-step explanation:

As the method of compounding is not stated, the default of simple interest will be used.

Simple interest is a fixed amount that is paid over the course of the loan and is based on the original amount borrowed.

Formula is:

Amount owed = Amount borrowed * ( 1 + rate * time)

= 8,000 * ( 1 + 8% * 5.5 years)

= 8,000 * 1.44

= rs 11,520
