Answer:

[tex]y=-4x+6[/tex]

Step-by-step explanation:

Point Slope Form = Y-y1=m(X-x1)

m=-4, (x1,y1) = (1,2)

y-2=-4(x-1)

y-2=-4x+4

y=-4x+6

m<A, which is 48 degree.

The values of mL and mJ are 55 and 61 degrees, respectively.

Since vertical angles are equal in magnitude and are created by intersecting two lines, they are known as the opposing angles.

what are the explanation of the problems?

1.Angles in the vertical plane coincide. They are equal in size, thus this indicates. Calculate x x = 4x - 24 by putting them on an equal footing. In the equation, deduct x from both sides.

o = 3x - 24 On both sides, add 24.

24 = 3x Divide both sides by 3

Multiply both sides by 3 

8 to get x 

m<A, which is 8.

4x-24

=3*8+24=24+24=48 degree

2.We can thus write,

The angles L and Z are vertical.

∠L = 2x + 9 and,

∠Z = 3x - 14.

Given that both angles are vertical,

∠L = ∠Z

2x + 9 = 3x - 14

Continuing to solve

3x - 2x = 9 + 14

x = 23

The value of L is therefore,

= 2(23)+9

= 46+9

= 55°

Angle L has a value of 55°.

2. Y and J are equal because they are both vertical angles.

∠Y = 7x + 12

∠J = 10x - 9

∠Y = ∠J

7x + 12 = 10x - 9

Continuing to solve

3x = 21

x = 7

So, the value of ∠J is, = 10(7) - 9 = 70 - 9 = 61°

The value of ∠J is 61°.

Answer:

Step-by-step explanation:The mean and Median salary would increase by $4,000.

Let sum of the salaries be n1+n2+n3+.......... +n30

   Mean = sum of observation / no. of observation

Thus,

   Initial mean, M1 = n1+n2+n3+.......... +n30 / 30

When $4,000 is added to every salary 4000 is added 30 times to the sum.

Thus,

  New mean, M2 = n1+n2+n3+.......... +n30 +( 4000 * 30)

                                                30

                           = M1 + ( 4000 * 30)

                                              30

  Thus,         M2 = M1+ 4000

Therefore, The mean salary increase by $4,000.

We know Median of even number of observation =  [(n/2)th term + ((n/2) + 1)th term]/2

Here n/2th term is n15 and (n/2 +1)th term is n16

Thus,

    Initial Median, Median 1 = n15 + n16  

                                                     2

When $4,000 is increased in each salary

    New Median, Median 2 = n15 + 4000 + n16 + 4000

                                                                 2

                                         = Median 1 + 2 * 4000

                                                                    2

Thus,                  Median 2= Median 1 + 4000

Therefore, The median salary increases by $4,000

The slope of the line that passes through the points (-7, -10) and (-19,-10) is 0.

Slope is simply expressed as change in y over the change in x.

It is expresses as;

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point 1 ( -7, -10 )

Point 2 (-19,-10)

Plug the given x and y values into the slope formula and simplify.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( -10 - (-10) )/( -19 - (-7) )

Slope m = ( -10 + 10 )/( -19 + 7 )

Slope m = ( 0 )/( -12 )

Slope m = 0/-12

Slope m = 0

Therefore, the slope of the line is 0.

x and y intercepts are the points where lines cut off the x and the y axis respectively.

In this case, the line cuts the x axis at x=-8. It means that the x intercept of the line is (-8,0).

The line also cuts the y axis at y=-6, which means that the y intercept of the line is (0,-6).

The transformation from the graph of f to the graph of g is reflection in the x-axis.

We are given the function f(x) = -4x + 8

Also it says that g(x) = -f(x)

                                 = 4x - 8

Since f(x) is a linear function, the graph of f(x) and hence the graph of g(x), both are straight lines. But the graph of g(x) will be a transformed image of the graph of f(x).

Here, if f(x) = y, then the transformation from f(x) to g(x) can be represented as, (x, y) -------> (x, -y)

This transformation corresponds to the reflection in the x-axis. When reflected along x-axis, the x- co-ordinate does not change, but the y- co-ordinate changes its sign. This is exactly what happens when the function f(x) is transformed to g(x) = -f(x).

a) 14.81 J of work is needed to stretch the spring from 29 cm to 31 cm.

b) 2 cm far beyond its natural length will a force of 15 N keep the spring in stretched position.

It is mentioned that 3 J of work is needed to stretch a spring from its natural length of 24 cm to 33 cm.

We know the work done on the spring is expressed by the following given equation:

[tex]W=\frac{1}{2} ke^{2}[/tex]

Where, W = workdone that is done on the spring

k = elastic constant

e = extension of the given material

So, Work (W) = 3 J and e = 33 cm - 24cm = 9 cm = 0.09 m

So, putting the above values we calculate the value of 'k' as below:

[tex]W=\frac{1}{2} ke^{2}[/tex]

⇒ [tex]3=\frac{1}{2} k(0.09)^{2}[/tex]

⇒ 3 x 2 = 0.0081k

⇒ k =  [tex]\frac{6}{0.0081}[/tex] N/m

⇒ k = 740.74 N/m

a) Now using the same formula for work, we will determine the amount of work that is needed to stretch the spring from 29 cm to a length of       31 cm.

k =  740.74 N/m

e = 31 cm - 29 cm = 2 cm = 0.02 m

[tex]W=\frac{1}{2} ke^{2}[/tex]

⇒ W = [tex]\frac{1}{2} (740.74) (0.02)^{2}[/tex]

⇒ W = 14.81 J

The work that is done to stretch the spring from 29 cm length to 31 cm is   14.81 J.

b) From the Hooke's law we have, F = ke, where F is the force applied on the spring. Now here we have been given that a force of 15N is applied and we have to find the 'e' that is the extennsion in the natural length of the given spring.

k = 740.74 N/m

F = 15 N

F = ke

⇒ 15 N = 740.74 x e

⇒ e = [tex]\frac{15}{740.74}[/tex] m

⇒ e = 0.02 m = 2 cm

Therefore the natural length of the spring will be stretched by a length of 2 cm when a force of 15 N is applied.

The first step here is to write out this question as a proper algebraic expression. That means you assign a letter to the question mark and you now have;

4/6 = y * 1/6

(Note that the symbol * represents the multiplication sign)

y * 1/6 can be re-written as y/6 since it is actually y/1 * 1/6

Therefore you now have;

4/6 = y/6

Cross multiply and you now have,

4 * 6 = y * 6

24 = 6y

Divide both sides of the equation by 6 (to eliminate the 6 on the right hand side)

m = slope

b = y-intercept

We need to get the slope and y-intercept of the line. To get the slope, two points will be picked on the line

Using points: (-8, -1) and (0, 2)

The y-intercept is the value of y when x = 0. On the graph, it is the value of y when the line crosses or touches the y-axis.

The line crosses the y axis at y = 2

b = y-intercept = 2

Rounding a number to a particular value reduces the complexity of the number while increasing readability and accessibility.

When you round to a certain point, the exact digits are maintained on the left side of that point but are rounded or somewhat trimmed from the right.

The limit is set at five.

All right-sided values are made zero if the right-side digit to the digit where we must round off is less than or equal to five; otherwise, it is increased by one and the remaining right-side digits are made zero. If the digit to the right of the decimal point is 5, and there are just zeros or no values after it, we round up (raise by 1 as in 347500 to 34800). (Well there are many detailed rules of rounding)

The following can be used to represent the provided expression, "pi plus the square root of forty to the closest hundredth,"
