If a mother is 20 years old when her baby is born how old will she be when she is twice as old as her child

Answer:

13.20

Step-by-step explanation:

1/5 (1+5+10+20+100) - 14

The required expected value is 13.20.

A box contains bill of = $1, $5, $10, $20, and $100
It costs $14 to reach in and withdraw one bill.

Its estimated value of the variable in probability.

Expected value=  mean - 14
                       =    (1+5+10+20+100)/5 -14
                       =    13.20

Thus, the required expected value is 13.20.

The price of 1 Kg (1000 g.) is 0.25 x 1000 = Rs 250

Answer:

the inverse of a function takes the output of the actual function as the input and gives the input of the initial function as the output

here, we are given that when we input 23 in the inverse function of 'f', we get 3

this means that if we input 3 in the initial function, we will get 23 as the output

f(x) = x² - ax + 8

changing the input value to 3

f(3) = (3)² - 3a + 8

changing the output value to 23

23 = 9 - 3a + 8

3a = 17 - 23

3a = -6

a = -2

Answer:

[tex]\displaystyle \left(-x+2, -\frac{1}{2}y-4}\right)[/tex]

Step-by-step explanation:

We are given that one of the endpoints of the line segment is:

[tex]\displaystyle \left( x + 4, \frac{1}{2}y\right)[/tex]

And that the midpoint of the line segment is (3, -2).

And we want to find the other coordinates in terms of x and y.  

We can consider using the midpoint formula:

[tex]\displaystyle M = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]

We are given that the midpoint is (3,-2). Substitute:

[tex]\displaystyle (3, -2) = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]

We can solve for each coordinate independently.

x-coordinate:

We have:

[tex]\displaystyle 3=\frac{x_1+x_2}{2}[/tex]

One of the two endpoints is (x + 4, 1/2y). Hence, we can substitute x + 4 for x₁:

[tex]\displaystyle 3=\frac{(x+4)+x_2}{2}[/tex]

Solve for the second x-coordinate x₂:

[tex]\displaystyle \begin{aligned} 6 & = x+4 + x_2 \\ \\ x_2 + x & = 2 \\ \\ x_2 & = -x +2 \end{aligned}[/tex]

Hence, the x-coordinate of the second point is -x + 2.

y-coordinate:

We have:

[tex]\displaystyle -2=\frac{y_1+y_2}{2}[/tex]

We can substitute 1/2y for y₁. This yields:

[tex]\displaystyle -2=\frac{\dfrac{1}{2}y+y_2}{2}[/tex]

Solve for y₂:

[tex]\displaystyle \begin{aligned} -4 & = \frac{1}{2}y + y_2 \\ \\ y_2 & = -\frac{1}{2}y - 4\end{aligned}[/tex]

In conclusion, the other coordinate expressed in terms of x and y is:

[tex]\displaystyle \left(-x+2, -\frac{1}{2}y-4}\right)[/tex]

Answer:

16 =x

Step-by-step explanation:

The angles are corresponding angles and since the lines are parallel, they are equal

5x+18 =7x-14

Subtract 5x from each side

5x+18 -5x=7x-5x-14

18 = 2x-14

Add 14 to each side

18+14 = 2x-14+14

32 = 2x

Divide by 2

32/2 = 2x/2

16 =x

Answer: x=16

Step-by-step explanation:

make it an equation: the equation 5x+18=7x-14

then, solve for x.

steps :

1. add 14 to both sides to get 5x+32=7x

2. subtract 5x to both sides to get 32=2x

3. divide both sides by 2 to get 16=x

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The graph of a function f is the set of all points in the plane of the form (x, f(x)).

For the given situation,

The graph below shows the functions tan(x) and arctan(x) that is tan^-1(x)

In order to have an inverse function for trigonometry, we restrict the domain of each function, so that it is one to one.

A restricted domain gives an inverse function because the graph is one to one and able to pass the horizontal line test.

Thus by restricting the domain [tex](-\frac{\pi }{2} ,\frac{\pi }{2} )[/tex] we can obtain the function [tex]tan(x)[/tex] as [tex]tan^{-1} (x)[/tex].

Hence we can conclude that the restriction that should be applied to the function [tex]y = tanx[/tex] for [tex]tan^{-1} (x)[/tex] to be defined is option (C) restrict the domain to [tex](-\frac{\pi }{2} ,\frac{\pi }{2} )[/tex] is the correct answer.

Answer:

x+6y-2 is the simplfied answer

Step-by-step explanation:

The transformation of the graph of f to the graph of g is that the graph is translated down 135 units.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given two functions are

f(x) = 12x – 1,400 and

g(x) = 12x – 1,535

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.

We need to find the transformation of the graph of f to the graph of g.

The graph is translates down 135 units, because the y-intercept decreased by 135 units from f(x) to g(x).

Hence,  the transformation of the graph of f to the graph of g is that the graph is translated down 135 units.

Answer:

6. Ethan should shade the region marked B

7. No, point (0, 4) will not be included in the solution set

8. Point (0, -2) will not be included in the solution set

Step-by-step explanation:

Let us explain how to solve the question

The graph represents the equation 2x - 5y = 10

The inequality is 2x - 5y > 10

The sign of inequality is greater than without equal, that means the line represents it must be a dotted line because all the points on the line do not belong to the solution set of the inequality.

To find the area of the solution you must put y on a side and the other term on the other side

∵ 2x - 5y > 10

→ Add 5y to both sides to move y in the other side

∴ 2x - 5y + 5y > 10 + 5y

∴ 2x > 10 + 5y

→ Subtract 10 from both sides to move 10 to the other side

∵ 2x - 10 > 10 - 10 + 5y

∴ 2x - 10 > 5y

→ That means 5y < 2x - 10

∴ 5y < 2x - 10

6.

→ y < that means the area of the solutions is under the line

∴ The solutions of the inequality lie in area B

∴ Ethan should shade the region marked B

7.

∵ Point (0, 4) lies above the line in the region marked A

→ That means it does not lie in the area of the solutions

∴ Point (0, 4) will not be included in the solution set

8.

∵ Point (0, -2) lies on the line

∵ All the point on the line did not belong to the solution set as we

  said before

∴ Point (0, -2) will not be included in the solution set
