The the tension in the string is 276 N. Thus, the correct answer is B.

The tension in the string provides the centripetal force needed to keep the ball moving in a circular motion. As the tension in the string increases, the centripetal force increases as well, and the ball will move in a smaller circle (the radius will decrease). Therefore, if the tension increases, the radius decreases and the velocity increases, and if the tension decreases, the radius increases and the velocity decreases.

To determine the tension in the string, we can use the equation:

Where m is the mass of the ball, v is the velocity of the ball, and r is the radius of the circle.

Dilation is the practice of altering an object's or shape's size by either enlarging or decreasing its dimensions by a certain amount.

A transform called dilation is used to alter an object's size. Dilation is a technique for enlarging or contracting objects.

The result of this transformation is an image that has the same shape as the original. A stretched figure can be enlarged by using given formula:

Scale is equal to the difference between the original and new shapes' sizes.

Stretch transformations (similarity transformations) enlarge or shrink shapes. You require a scale factor of k and a central point. Depending on the value of k, the expansion either grows or shrinks. Elongation is elongation for |k| > 1. If 1 is stretched, for |k|.

The scale factor of Reggie's drawing is 1/500.

The scale factor of a drawing is the ratio of the size of the drawing to the size of the real object.

To find the scale factor of Reggie's drawing, we can use the information given: in real life, the garage is 3 meters wide, and in the drawing, it is 6 millimetres wide.

We know that:

Scale factor = size of drawing/size of the real object

We can use this equation to find the scale factor of Reggie's drawing:

Scale factor = 6 millimetres / 3 meters

To make the units consistent, we need to convert 3 meters to millimetres.

1 meter = 1000 millimeters

So, 3 meters = 3 * 1000 millimeters = 3000 millimeters

Now we can substitute this value into the scale factor equation:

Scale factor = 6 millimetres / 3000 millimetres

Simplifying the fraction: Scale factor = 1/500

Therefore, the scale factor of Reggie's drawing is 1/500. This means that every 1 millimetre on the drawing represents 500 millimetres (or 0.5 meters) in real life.

As given DB² = DA² + AB²

As given

DB = 13 units

AB = 9 units

Putting values in the above

13² = 9²+ DA²

169 - 81 = DA²

88 = DA²

DA=√88

In ΔABC

AB² = AC² + CB²

(As given AB = 9 units , CB = x)

AC ² = 81 - x²

Now in ΔADC.

AD² = AC² + DC ²

As AC ² = 81 - x²

DC = 13 - x

AD=√88

(√88)²=81-x²+(13-x)²

The side lengths of the new right triangle can be determined by the ratio of the given triangle.

A triangle is a three-sided polygon with three straight sides that are connected at three corners. It is one of the most basic shapes in geometry and is found in many areas of mathematics. Triangles can be classified according to their angles, sides, and size. They can be equilateral, isosceles, or scalene, depending on the size of their angles and sides. Triangles are used in a variety of fields, including architecture, engineering, construction, art, and design.
The side opposite the 30° angle will always be half the length of the hypotenuse, while the side opposite the 60° angle will always be equal to the square root of three times the length of the side opposite the 30° angle. This means that if the hypotenuse of the given triangle is 2, then the side opposite the 30° angle will be 1 and the side opposite the 60° angle will be √3.

Therefore, for any other right triangle containing a 30° or a 60° angle, the side length can be found by multiplying the side length of the given triangle by the same ratio. For example, if the hypotenuse of the new triangle is 6, then the side opposite the 30° angle will be 3 and the side opposite the 60° angle will be 3√3.

In conclusion, for any right triangle containing a 30° or a 60° angle, the side lengths can be determined by multiplying the side lengths of the given triangle by the same ratio.

Answer:

AI's Auto Shop: y = 149 + 53x

Edna's Engine Repair: y = 280

Explanation:

The system of equations represent the costs of the two different repair shops. The first equation, y = 149 + 53x, represents the total cost of AI's Auto Shop. The variable x represents the number of hours of labor required, and the variable y represents the total cost. The second equation, y = 280, represents the flat fee charged by Edna's Engine Repair.

The graph of the system of equations would show two lines, one for each equation. The line for AI's Auto Shop would have a slope of 53 and a y-intercept of 149, representing the cost of parts and hourly labor. The line for Edna's Engine Repair would be a horizontal line at y = 280, representing the flat fee charged.

When the job takes 2 hours, AI's Auto Shop would charge $149 + $53*2 = $255 and Edna's Engine Repair would charge $280. So, AI's Auto Shop would be cheaper.

For a job that takes 3 hours, AI's Auto Shop would charge $149 + $53*3 = $308 and Edna's Engine Repair would charge $280. So, AI's Auto Shop would be more expensive.

The distance between the 7th seconds and the 10th seconds is  29.4 m.

It is arithmetic.

An arithmetic progression (AP) is a sequence of numbers in which the difference between any two consecutive terms is always the same, called the common difference.

Since the height in the 1st second, 2nd second and 3rd second are 4.9m, 14.7 and 24.5 respectively.

They have a common difference (d) of 9.8. That is:

d = 14.7 - 4.9 = 9.8  

Thus, it is arithmetic

The formula for determining nth of an AP is given by:

nth = a + (n-1)d

where a is the first term, d is the common difference and n is the number of terms

7th seconds:

nth = a + (n-1)d

nth = 4.9 + (7-1)9.8 = 63.7 m

10th seconds:

nth = a + (n-1)d

nth = 4.9 + (10-1)9.8 = 93.1 m

distance between the 7th and the 10th seconds:

10th seconds - 7th seconds = 93.1 - 63.7 = 29.4 m

The inverse of the function f(x) and its domain include the following: D. f⁻¹(x) = (x + 4)²; x ≥ 0.

In Mathematics, an inverse function simply refers to any type of function that is typically generated by reversing the mathematical operation in a given function (f(x)).

In order to determine the inverse of any function, you should swap both the input value (x-value) and output value (y-value) as follows;

f(x) = √x - 4

y = √x - 4

x = √y - 4

√y = x + 4

Taking the square of both sides of this inverse function, we have:

f⁻¹(x) = (x + 4)²

For the domain of this function, we have:

f(x) = √x - 4

When x= 0, we have:
