The measurement of length of the car is 2.25m, when the width is 1.5 meter. Thus, option B is correct.

Measurement is the process of relating numerical values to physical quantities and phenomena. The sciences, engineering, construction, and other technical fields, as well as nearly all daily activities, all depend on measurement. The components, circumstances, restrictions, and theoretical underpinnings of measurement have thus been extensively studied.

Measurements can be made using only the human senses, in which case they are frequently referred to as estimates, or, more frequently, by using instruments.

These instruments can range in complexity from straightforward rules for measuring lengths to extremely complex systems built to detect and measure things that are completely outside the range of the senses, like radio waves from a far-off star or the magnetic moment of a subatomic particle.

Given that length : width is  3 : 2

let length be 3x and width be 2x

width is given 1.5m

2x = 1.5

x = 1.5/2

x = 3/4

Length = 3x

If a figure can be transformed into another figure by a sequence of translations, rotations, and reflections, and the size and shape remain the same, the figures are congruent.

A congruence transformation is a type of transformation that preserves the size and shape of a figure. The most common congruence transformations are translations, rotations, and reflections.

Translations involve moving a figure a certain distance in a certain direction without changing its size or orientation.

Rotations involve rotating a figure around a certain point without changing its size or shape.

Reflections involve flipping a figure over a certain line without changing its size or shape.

In order to show that two figures are congruent, you can use a combination of these congruence transformations to match one figure to the other. By using these transformation you can map each point of one figure to a corresponding point on the other figure and if the size and shape of figures remain the same, that means that the figures are congruent.

It's important to notice that Congruence is an equivalence relation and it's reflexive, symmetric, and transitive.

1) FInd the sides of small triangle. Since it has 2 congruent angles it also has to congruent sides opposite those angles. So the sides adjacent (connected to) the right angle are both 6.

2) Find the hypotenuse (side opposite the right angle) in the small triangle

a^2 +b^2 = c^2

6^2 +6^2 = c^2

36+36 = c^2

72 = c^2

c = [tex]\sqrt{72}[/tex]

In simplified radical form  [tex]\sqrt{72\\[/tex] = 6[tex]\sqrt{2}[/tex]

3) Now find the sides of big triangle. It has 2 congruent angles therefore it has two congruent side opposite those angles. We know that one of the sides is 6[tex]\sqrt{2}[/tex] because it is also the hypotenuse of the small triangle. The other side adjacent to the right angle is also 6[tex]\sqrt{2}[/tex].

4) Now find x which is the hypotenuse of the big triangle.

[tex](6\sqrt{2} )^{2}[/tex]+                    [tex](6\sqrt{2} )^{2}[/tex]= [tex]c^{2}[/tex]

The best estimate of the average change in rent each year include the following: C. $40.

Mathematically, the rate of change is also referred to as slope or gradient and it can be calculated by using this formula;

Rate of change, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change, m = (y₂ - y₁)/(x₂ - x₁)

Next, we would determine the rate of change of the value of y with respect to the value of x on the scatter plot, which represents a line that is passing through the points (0, 800) and (10, 1200):

Rate of change, m = (1200 - 800)/(10 - 0)

Now, According to the question:

600 [tex]u^2[/tex] of land to be enclosed by fence

Area inside plot should be maximized, amount of fence should be minimized

If we draw a quick sketch, we get something like this:

_____ _____

|        |         |

|        |         |

|        |         |

|        |         |

The two rectangles could be different sizes but if one rectangle size maximizes area then it would make sense to use that some rectangle for both sides.

Let's put some variables into our picture so we can define our constraints.

       y        y  

  |         |        |

x |      x |      x |

  |         |        |

  |         |        |

Now we just need an equation to connect our unknowns (how much fence to use) to our constraint (it has to have an exact area of 600 u^2.

A = x × 2y = area = 600

P = 3x + 4y = perimeter = a minimum

First we solve the area equation for y:

y = [tex]\frac{600}{2x}[/tex] = [tex]\frac{300}{x}[/tex]  

and then we substitute that result into our perimeter equation:

P = 3x + 4 (300/x)

P = 3x + 1200/x

Our perimeter equation is: P(x) = 3x + 1200/x OR P(x) = 3x +1200[tex]x^-^1[/tex]

We can find what value of x makes our perimeter as small as possible (a minimum) by graphing or by using Calculus.

In Calculus we know that maximums and minimums always occur when the derivative is zero. This is because the slope (rate of change) at these points in a graph are always flat or zero. Our derivative is

P'(x) = 3 - 1200[tex]x^-^2[/tex]

When set equal to zero, we can solve for x:

3 - 1200[tex]x^-^2[/tex]= 0

1 - 400[tex]x^-^2[/tex] = 0

1 = 400/[tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 400

x = ± 20

Our fence length can't be a negative number so our answer must be 20u.

If our x length is 20, then our y length must be 300/x to ensure our area is 600 u^2.

The y length is 300/(20) = 15

Let's put all of our numbers into our picture to see if it make sense.

      15      15    

    |        |         |

20 |    20 |    20 |

    |        |         |

    |        |         |

       15      15

Sure enough our area is 600.

Here's what we have right now:

A(20, 15) = 600

P(20, 15) = 120

How about we try something a little bigger like 20.5 for x and 14.63 for y?

A(20.5, 14.63) = 600

P(20.5, 14.63) = 120.02

How about we try something a little smaller like 19.5 for x and 15.38 for y?

A(19.5, 15.38) = 600

P(19.5, 15.38) = 120.02

It looks like if we try to change x, even a little, to make it bigger or smaller the perimeter only gets bigger.

You might have guessed at the beginning that a square is the best shape to use to maximize area, so let's try that as well.

Each rectangle is 300 u^2. We want a square so each side would be √(300) = 17.32

              17.32         17.32    

        |                |                 |

17.32 |       17.32 |        17.32 |

        |                |                 |

             17.32          17.32

A(17.32, 17.32) = 600

P(17.32, 17.32) = 121.24

Hence, The dimensions of the rectangular plot that require the least amount of fencing is :

A(17.32, 17.32) = 600

The radius of the signal is 10 units. The 1st option is the answer

The equation of a circle is a mathematical expression that describes the properties of a circle. It is typically represented in the form of (x - h)²+ (y - k)² = r², where (h, k) is the center of the circle, and r is the radius

Since the border is modeled by the equation (x – 10)² + y²= r² and the boundary is located at (2, 6).

To get the radius of the signal substitute x = 2 and y = 6 into the given equation and solve for r:

(x – 10)² + y²= r²

(2 – 10)² + 6²= r²

(-8)² + 6²= r²

64 + 36 =  r²

A. The total number of points of intersection of the graphs of the equations y = 5e^x and xy = 20 is two.

To find the points of intersection, we must solve the two equations for x and y.

For the first equation, y = 5e^x, we can solve for x by taking the natural logarithm of both sides and getting x = ln(y/5).

For the second equation, xy = 20, we can solve for y by dividing both sides by x and getting y = 20/x.

We can then substitute the expression for x in terms of y into the expression for y in terms of x and solve for y to get y = 20/(ln(y/5)). This is a nonlinear equation that must be solved numerically.

By using numerical methods, we can solve the equation and find the two points of intersection, which are (x, y) = (3.68, 4.64) and (x, y) = (0.87, 22.95).

Essentially, the procedure identifies two points on the line (P and Q) that are equidistant from the external point (R), then proceeds to draw a perpendicular bisector of the segment between those two points. The external point is already equidistant from P and Q, so we only need to find another equidistant point (S) to complete the construction.

wood (m) = (6 ft x 0.3048) / 6

wood (m) = 1.8288 m      

Therefore, the amount of wood, in meters, needed to rebuild the frame is 1.8288 m.
