Answer:

We have been given the points origin and P (4,3)

We have reflection rule which is:

(x,y)\text{when reflected around y-axis}\Rightarrow(-x,y)

(x,y)\text{when reflected around x-axis}\Rightarrow(x,-y)

The given point x=4 and y=3 when reflected around y-axis the point becomes:

(-4,3)

The given point x=4 and y=3 when reflected around x-axis the point becomes:

(4,-3)

Answer with explanation:

When a point is reflected across either through x or y axis ,then perpendicular distance of that point from x or y axis called Preimage is equal to perpendicular distance of that point from x or y axis called image.

When a point is reflected through x axis or y axis,it totally depends on which quadrant the point is lying.

If point(a,b) is lying in first Quadrant ,and then we have to find it's reflection across x axis and y axis then coordinate of image point will be ,which will lie in fourth Quadrant and second quadrant respectively ,will have coordinates  (a,-b) and (-a,b) respectively.

These are rules of reflection across x and y axis of point(a,b),where a and b are positive real number

(a,b)_{x}=(a,-b)\\\\(a,b)_{y}=(-a,b)\\\\(-a,b)_{x}=(-a,-b)\\\\(-a,b)_{y}=(a,b)\\\\(-a,-b)_{x}=(-a,b)\\\\(-a,-b)_{y}=(a,-b)\\\\(a,-b)_{x}=(a,b)\\\\(a,-b)_{y}=(-a,-b)

Using the Same rule when point (4,3) is reflected around x and y axes

(4,3)_{x}=(4,-3)\\\\(4,3)_{y}=(-4,3)

A coordinate plane with the x-axis labeled Blueberries (in pints) and the y-axis labeled Cost (in dollars) shows a line going through (0, 0) and (5, 17).

<h3>What is directly proportional?</h3>

It is defined as the relationship between two quantities as one quantity increases the other quantity also increases and vice versa.

It is given that there is a proportional relationship between cost and pints of blueberries as,

Blueberries (in pints)          2      5

Cost (in dollars)                6.80   17

17/6.80 = 5/2

As we draw the graph and analyze each option one by one we get the graph shown by the statement C following the given proportional relationship.

Thus, a coordinate plane with the x-axis labeled Blueberries (in pints) and the y-axis labeled Cost (in dollars) shows a line going through (0, 0) and (5, 17).

I'm not sure where to start and how to differentiate this.
Mazyrski [523]
The picture is not clear. let me assume y = (x^4)ln(x^3)

product rule :
d f(x)g(x) = f(x) dg(x) + g(x) df(x)

dy/dx = (x^4)d[ln(x^3)/dx] + d[(x^4)/dx] ln(x^3)
= (x^4)d[ln(x^3)/dx] + 4(x^3) ln(x^3)

look at d[ln(x^3)/dx]
d[ln(x^3)/dx]
= d[ln(x^3)/dx][d(x^3)/d(x^3)]
= d[ln(x^3)/d(x^3)][d(x^3)/dx]
= [1/(x^3)][3x^2] = 3/x
... chain rule (in detail)

end up with
dy/dx = (x^4)[3/x] + 4(x^3) ln(x^3)
= x^3[3 + 4ln(x^3)]

Which shape has a line of symmetry that can be drawn through the figure?
zimovet [89]

Answer: Option D.

Step-by-step explanation:

A figure has a line of symmetry if we can draw a line through the figure, in such way that the line cuts the figure in exactly two equal halves.

Then any figure that can be cutin exactly two halves, is a correct answer to this question.

Then:

For a circle, the line of symmetry is the diameter of the circle.

For the square, the line of symmetry can be obtained by cutting the square with a line that is perpendicular to one of the sides, and cuts that side exactly on the midpoint.

For an equilateral triangle, the line of symmetry is the line that cuts any base in the midpoint and also passes through the opposite vertex.

Then all the figures are correct options, then the correct option is D
