Check the picture below.

well, HIJK is a parallelogram only if its diagonals bisect each other, if that's so, the midpoint of HJ is the same as the midpoint of IK, let's check

Answer:

1. bisect each other 2. (2,2) 3. have the saem midpoint

Step-by-step explanation:

The coordinates of the vertices for the figure HIJK are H(0, 5), I(3, 3), J(4, –1), and K(1, 1).

To determine if it is a parallelogram, use the converse of the parallelogram diagonal theorem. This states that if the diagonals

✔ bisect each other

, then the quadrilateral is a parallelogram.

The midpoint of HJ is

✔ (2, 2)

and the midpoint of IK is (2, 2).

Therefore, HIJK is a parallelogram because the diagonals

✔ have the same midpoint

, which means they bisect each other.

The rectangular coordinates will be (x=7cot(θ), y=7).

A pair of coordinates locating the position of a point in a plane, the first being the length of the straight line ( r ) connecting the point to the origin, and the second the angle ( θ ) made by this line with a fixed line.

We have the standard conversion toolbox:

[tex]x=rcos(\theta)\\\\y=rsin(\theta)[/tex]

Here it is given that

[tex]r=7cosec(\theta)[/tex]

so

[tex]x=7cosec(\theta)\times cos(\theta)=\dfrac{7cos(\theta)}{sin(\theta )}=7cot(\theta)\\\\\\y=7cosec(\theta)\times sin(\theta)=\dfrac{7sin(\theta)}{sin(\theta)} = 7[/tex]

therefore the rectangular coordinates are (7cot(θ), 7)

Let the present age of Meena be ' x ' years.

That means,

Present age of her mother

[tex]\sf{ = 4x \: years }[/tex]

Now,

After 5 years

The age of the Meena will be

[tex]\sf{ = x + 5 \: years }[/tex]

Therefore,

According to given condition,

The age of her mother will be

= [tex]\sf{ = 4x + 5 \: years ...eq(1)}[/tex]

But, It is given that,

That is,

After 5 years, Her mother age will be

[tex]\sf{ = 3(x + 5) \: years ...eq(2)}[/tex]

From eq(1) and (2) :-

[tex]\sf{ 4x + 5 = 3(x + 5) }[/tex]

[tex]\sf{ 4x + 5 = 3x + 15}[/tex]

[tex]\sf{ 4x - 3x = 15 - 5 }[/tex]

[tex]\sf{ x = 10 \: years }[/tex]

Thus, The present age of the Meena will be 10 years.

Therefore,

The present age of her mother will be

[tex]\sf{ 4x = 4 × 10 }[/tex]

[tex]\sf{ = 40 \: years }[/tex]

Hence, The present of Meena and her mother is 10 years and 40 years.

The equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Let's suppose the equation that models the exponential decline is:

[tex]\rm y = a(b^x)[/tex]

From the data given, we can calculate the value of a and b:

a = 46348587109809610

b = 0.9861

y = 46348587109809610(0.9861)ˣ

Thus, the equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.

An expression is defined as a set of numbers, variables, and mathematical operations. The simplification of the expression (5x/x^2-1 )×(x+1/x^2) is 5/x(x-1).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The simplification of the given expression can be done as,

Answer:

the slope of parallel lines are - the same

i.e,m1=m2

the slope of perpendicular lines are- negative reciprocals

i.e,m1*m2= -1

where, m1 and m2 slopes of two lines

A. The slope of parallel lines are: the same/equal

B. The slope of perpendicular lines are negative reciprocals.

If two lines are parallel to each other, they will have the same slope. If the slope of one is 4, the slope of the other line that is parallel to it would also be 4.

On the other hand, the slope of perpendicular lines are negative reciprocal of each other. That is, if the slope of one is, -1, the slope of the other line would be 1.

Therefore, parallel lines have the same slope, while perpendicular lines have slope values that are negative reciprocal to each other.

Answer:

  £54,915

Step-by-step explanation:

The tax table is applied as follows:

  first 11,000 -- no tax

  11,000 to 43,000 -- tax is 0.20 × (43,000 -11,000) = 6,400

  43,000 to 150,000 -- tax is 0.40 × (150,000 -43,000) = 42,800

  150,000 to 162,700 -- tax is 0.45 × (162,700 -150,000) = 5,715

Then the total tax on earnings of £162,700 is ...

  £6,400 +42,800 +5,715 = £54,915

Nerys paid a tax of £54,915.

Additional comment

The tax computation could be simplified to ...

  f(x) = max(0, 0.2x -2200, 0.4x -10800, 0.45x -18300)

In this instance, the value 0.45x -18300 is the highest, at £54,915. Not all the computations are required if you realize the lines cross at x = 11,000, 43,000, and 150,000.

Answer:

17 cm and 31 cm

12 cm and 36 cm

18 cm and 30 cm

Step-by-step explanation:

The midsegment of a trapezoid is equal to the average of the two bases. When taking an average of two numbers, you add them and divide by 2. So  the equation will be as follows:

[tex]\frac{PQ + SR}{2} = XY[/tex]

XY is given to be 24, so:

[tex]\frac{PQ + SR}{2} = 24[/tex]

Multiplying on both sides gets us:

[tex]PQ + SR = 48[/tex]

So any values of PQ and SR that add to 48 work. Therefore, we will sum the given options:

17 cm + 31 cm = 48 cm

18 m + 30 m = 48m (Did you mean meters?)

4 cm + 8 cm = 12cm

9 cm + 15 cm = 24cm

12 cm + 36 cm = 48cm

18 cm + 30 cm = 48 cm
