Answer:  L isn't the midpoint of segment MN.

Step-by-step explanation:

NL+LM=NM

6x-5+2x+3=4x+9

8x-2=4x+9

8x-2+2=4x+9+2

8x=4x+11

8x-4x=4x+11-4x

4x=11

Divide both parts of the equation by 2:

2x=5.5

NL=6x-5

NL=(2x)(3)-5

NL=(5,5)(3)-5

NL=16.5-5

NL=11.5

LM=2x+3

LM=5.5+3

LM=8.5

NL≠LM

Hence, L isn't the midpoint of segment MN.

In summary, based on the given lengths and mathematical reasoning, we have determined that point L is the midpoint of segment MN because the lengths of NL and LM are equal when x = 2.

We must compare the lengths of the two segments NL and LM and see if they are identical in order to establish whether point L is the midpoint of segment MN.

NL = 6x - 5

LM = 2x + 3

The lengths of NL and LM ought to be equal if L is the middle of segment MN. To put it another way, NL and LM ought to be equal.

Constructing the equation

6x - 5 = 2x + 3

Now, solve for x:

6x - 2x = 3 + 5

4x = 8

x = 2

As soon as we know the value of x, we can put it back into the NL and LM formulas to get their lengths at x = 2:

NL = 6x - 5 = 6 * 2 - 5 = 12 - 5 = 7

LM = 2x + 3 = 2 * 2 + 3 = 4 + 3 = 7

The lengths of NL and LM are both 7 units.

Point L is in fact the middle of segment MN because both segments NL and LM have similar lengths.

It lies in the quadrant IV.

Since we know that a full circle is broken into four parts known as quadrants into regions of π/2.Since quadrant  1 ranges from 0 to π/2,  quadrant 2 ranges from π/2 to π, then quadrant 3 ranges from π to 3π/2, and at last quadrant 4 ranges from 3π/2 to 2π.

And we know 2π is equal to approx  6.28 radians,  so each quadrant will have  2π/ 4 = π2  ≈1.57 radians

So for angle  -7 it will be =  −7/(π/2) ≈−4.45.

Answer:

16,300,000 viewers

Step-by-step explanation:

We have two ordered pairs and we can write an equation in the slope intercept form of the line from the information that we have.

y = mx + b  y is the number of viewers and x in the number of minutes of ads.

m is the slope.  That is the change in y over the change in x.  We will use the two points given to find this.

(14, 10,000,000) (25, 17,000,000)  

slope:

[tex]\frac{y{1}- y{2} }{x_{1}-x_{2} }[/tex] = [tex]\frac{17,000,000 - 10,000,000}{25-15}[/tex] =[tex]\frac{7,000,000}{10}[/tex] = 700,000

Now we need the b or the y-intercept.  We will use the slope and one of the points to find this.  We could use either point. I am going to use the point (15, 10,000,000)

y = mx + b

I will use 10,000,000 for y

I will use 15 for x

I will use 700,000 for the slope.

I will plug these numbers in and solve for b

10,000,000 = 700,000(15) + b

10,000,000 = 10,500,000 + b  Subtract 10,500,000 from both sides

-500,000 = b

Now we can write the equation

y = mx + b

y = 700,000x -500,000 Plug is the 24  for x to solve for the number of views.

y = 700,000(24) -500,000

y = 16,800,000 - 500,000

y = 16,300,000

Step-by-step explanation:

1. Hans needs to rent a moving truck. Suppose Company A charges $40.00 per day and Company B charges a $60.00 fee plus $20.00 per day, for what number of days is the cost the same?

Let x = # of days, since Company A charges $40/day then cost after x days = 40x

Let x = # of days, since Company B charges $20/day plus $60 fee, then cost after x days = 20x + 60

a. For what # of days is the cost the same?

   When the cost is the same => 40x = 20x + 60

                                                    40x - 20x = 60

                                                             20x = 60

                                                                 x = 60/20

                                                                 x = 3

 The cost is the same after 3 days.

 Checking:

$40(3)  = $20(3) + $60

$120    = $60 + $60

$120    = $120

The Expression for the Area a of the rectangle as a function of length L is given by A(L) = 12L - L^2 .

Let,

length, L, and the width, W, are components that help determine the area, A, and the perimeter, P of the rectangle. These are given by the following equations

 A=LW

 P=2L+2W

Given,

Perimeter of the Rectangle = 24m.

We are asked to express the perimeter of the rectangle as a function of the length, L, of one of its sides.

We will first set up the equation of the Perimeter of the rectangle. We can let the width of the rectangle be W.

P = 2L+2W

24 = 2L+2W

12 = L+W

W = 12-L

Since we want to express the Area as a function of L, we have to find the value of W in terms of L. This is so we can eliminate the width in the equation for the Area. The Area as a function of L is as follows.

A(L, W) = LW

A(L) = L(12-L)

A(L) = 12L-L^2

Therefore, the Area as a function of L is given by A(L) = 12L-L^2.

The equation of the line y = -4.2x + 7.9 expressed in standard form is 42x + 10y = 79.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is written as axe + by = c, where a and b are the coefficients of the variables x and y, respectively, and c is a constant. On the other hand, we can write the equation in point-slope form, (y - y1) = m, if we know the slope m and a point on the line (x, y).

Given the equation of a line, multiply both sides by 10 to turn the decimals into integers.

y = -4.2x + 7.9

10y = 10(-4.2x + 7.9)

10y = -42x + 79

Then

using vectors,

n =  j + 0.20 k

e = i + 0.25 k

And the

n · e = 1x0 + 0x1 + 0.20×0.25 = 0.05

Now take magnitude then

|n|·|e| = i(1² + 0.20²)·i(1²+0.25²) = 1.105
