Find the point (,) on the curve =8 that is closest to the point (3,0). [To do this, first find the distance function between (,) and (3,0) and minimize it.]

Answers

Question:

Find the point (,) on the curve [tex]y = \sqrt x[/tex] that is closest to the point (3,0).

[To do this, first find the distance function between (,) and (3,0) and minimize it.]

Answer:

[tex](x,y) = (\frac{5}{2},\frac{\sqrt{10}}{2}})[/tex]

Step-by-step explanation:

[tex]y = \sqrt x[/tex] can be represented as: [tex](x,y)[/tex]

Substitute [tex]\sqrt x[/tex] for [tex]y[/tex]

[tex](x,y) = (x,\sqrt x)[/tex]

So, next:

Calculate the distance between [tex](x,\sqrt x)[/tex] and [tex](3,0)[/tex]

Distance is calculated as:

[tex]d = \sqrt{(x_1-x_2)^2 + (y_1 - y_2)^2}[/tex]

So:

[tex]d = \sqrt{(x-3)^2 + (\sqrt x - 0)^2}[/tex]

[tex]d = \sqrt{(x-3)^2 + (\sqrt x)^2}[/tex]

Evaluate all exponents

[tex]d = \sqrt{x^2 - 6x +9 + x}[/tex]

Rewrite as:

[tex]d = \sqrt{x^2 + x- 6x +9 }[/tex]

[tex]d = \sqrt{x^2 - 5x +9 }[/tex]

Differentiate using chain rule:

Let

[tex]u = x^2 - 5x +9[/tex]

[tex]\frac{du}{dx} = 2x - 5[/tex]

So:

[tex]d = \sqrt u[/tex]

[tex]d = u^\frac{1}{2}[/tex]

[tex]\frac{dd}{du} = \frac{1}{2}u^{-\frac{1}{2}}[/tex]

Chain Rule:

[tex]d' = \frac{du}{dx} * \frac{dd}{du}[/tex]

[tex]d' = (2x-5) * \frac{1}{2}u^{-\frac{1}{2}}[/tex]

[tex]d' = (2x - 5) * \frac{1}{2u^{\frac{1}{2}}}[/tex]

[tex]d' = \frac{2x - 5}{2\sqrt u}[/tex]

Substitute: [tex]u = x^2 - 5x +9[/tex]

[tex]d' = \frac{2x - 5}{2\sqrt{x^2 - 5x + 9}}[/tex]

Next, is to minimize (by equating d' to 0)

[tex]\frac{2x - 5}{2\sqrt{x^2 - 5x + 9}} = 0[/tex]

Cross Multiply

[tex]2x - 5 = 0[/tex]

Solve for x

[tex]2x =5[/tex]

[tex]x = \frac{5}{2}[/tex]

Substitute [tex]x = \frac{5}{2}[/tex] in [tex]y = \sqrt x[/tex]

[tex]y = \sqrt{\frac{5}{2}}[/tex]

Split

[tex]y = \frac{\sqrt 5}{\sqrt 2}[/tex]

Rationalize

[tex]y = \frac{\sqrt 5}{\sqrt 2} * \frac{\sqrt 2}{\sqrt 2}[/tex]

[tex]y = \frac{\sqrt {10}}{\sqrt 4}[/tex]

[tex]y = \frac{\sqrt {10}}{2}[/tex]

Hence:

[tex](x,y) = (\frac{5}{2},\frac{\sqrt{10}}{2}})[/tex]

Consuelo recorded the amount of time, in minutes, she spent exercising on the treadmill. 15, 25, 30, 25, 45, 20, 35, 30, 35, 30, 40 Which value best represents the mode? 10 min 10 min 30 min 30 min 35 min 35 min 25 min

Answers

Answer: 30 mins.

Step-by-step explanation:

The mode is the value that appears the most times.

In such a situation, first order the numbers in an ascending order:

15, 20, 25, 25, 30, 30, 30, 35, 35, 40, 45

As can be seen from the above, 30 is the number that appears the most so the mode is 30 mins.

Jane made a door frame for the house but does not have a tool to measure the angles. How can she check that the corner is 90 degrees?

She can use any square object around her. Since squares are made up of right angles, any side she chooses can be used to compare the angle of the door. If the square corner fits perfectly, the angle is 90. If the square fits with space, obtuse. If the square doesn’t fit, acute

Step-by-step explanation:

a rectangle is 16 feet long and 8 feet wide find its area

Answers

The area of the rectangle is 128 square feet.

To find the area of a rectangle, you multiply the length by the width. In this case, the rectangle is 16 feet long and 8 feet wide.

Area = Length * Width

Substituting the given values:

Area = 16 feet * 8 feet

To perform the calculation, multiply the numbers:

Area = 128 square feet

Therefore, the area of the rectangle is 128 square feet.

The area of a rectangle represents the total amount of space enclosed within its boundaries. In this case, the rectangle measures 16 feet in length and 8 feet in width, so the area is calculated as 16 feet multiplied by 8 feet, resulting in 128 square feet.

The concept of area is fundamental in geometry and is used to measure the size of two-dimensional shapes. In the case of a rectangle, the area represents the product of its length and width, as every point within the rectangle contributes to its overall size.

Knowing the area of a rectangle can be useful in various situations. For example, if you want to determine how much flooring material is required to cover a rectangular room, you would need to know the area of the floor.

Triangle GHI is the right angled triangle.

Step-by-step explanation:

A right angled triangle follows the pythagoras theorem where,

h² = p² + b²

h is the longest side.

So,

15² = 12² + 9²

225 = 144 + 81

225 = 225

Hence this follow the pythagoras theorem and is a right angled triangle.
