Answer:

4.5 > x

Step-by-step explanation:

19 > 2x + 10

19 - 10 > 2x + 10 - 10

9 > 2x

9/2 >2x/2

9/2 > x

or

4.5 > x

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.

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.

In Quadrant III, all values of tan and cot are positive.

⇒ tanθ = 1/(3/4)

⇒ tanθ = 4/3

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,

[tex]\dfrac{5x}{x^2-1} \times \dfrac{x+1}{x^2}\\\\=\dfrac{5x}{x^2-1^2} \times \dfrac{x+1}{x^2}\\\\=\dfrac{5x}{(x+1)(x-1)} \times \dfrac{x+1}{x^2}\\\\= \dfrac{5}{(x-1)x}[/tex]

Hence, the simplification of the expression (5x/x^2-1 )×(x+1/x^2) is 5/x(x-1).

7874

7874 rounded to 1 sf

if the previous digit is 5 or more round up, if not keep it as it is.

1 sf= 8000

therefore, 7874 rounded to 1 sf is 8000.

Answer:

8000

Step-by-step explanation:

Since the leftmost 7 is in the thousands place, you need to round the number to the nearest thousand. The digit to the right of the first 7 is an 8, so 7 goes up 1 to 8.

Answer:

The vertex is (5, -9).

Step-by-step explanation:

One way of approaching this problem consists of finding the roots.  Seet the quadratic equal to zero and solve for x:  {2, 8}.

The axis of symmetry is exactly halfway between 2 and 8:  x = 5.

Now find the y-component of the vertex by evaluating f(5):

f(5) = (5 - 8)(5 - 2) = -9

The vertex is (5, -9).  This is the minimum value of the function.  The graph of this quadratic opens up.

The solution of the graphed system of equations y = -x² + x + 2 and y = -x + 3 is (1,2)

The system of equations is given as:

y = -x² + x + 2

y = -x + 3

From the graph in the complete question, we have the following point of intersection between the equations

(x,y) = (1,2)

The point of intersection between the equations is the solution

Hence, the solution of the graphed system of equations is (1,2)

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.
