The yaw mark's radius is 11.2 feet, or one foot to the nearest tenth.

11.1634 miles per hour is considered the minimum speed.

Yaw marks are always curved. They are, initiated by a steering input. They're the remains of a tire that's still moving while also slapping sideways.

Using a chord and middle ordinate, you can calculate the radius using the following formula:

We must apply the algorithm to get the yaw mark's radius.

where the middle ordinate is m and the chord's length is c

With a 31 foot chord and a 3 foot middle ordinate, the tires leave a yaw mark.

so,

[tex]r^{2}=\frac{31^{2} }{8*3} + \frac{3}{2}[/tex]

[tex]r^{2} =[/tex] 40.041 + 1.5

[tex]r^{2}[/tex] = 41.041

We will now apply the following formula to get the minimum speed:

where 'f' is the drag factor and 'r' is the radius

0.2 is the drag factor, hence f=0.2

and r=41.541 feet

[tex]s= \sqrt{15*0.2*41.041}[/tex]

[tex]s=\sqrt{124.623}[/tex]

s= 11.1634 mph

For a BOAT isosceles trapezoid. The length of the median is 9 ..

An isosceles trapezoid must have two non-parallel sides of equal length. Therefore, use the information provided to apply the following formula: circumference = base 1 base 2 (legs), where the length of the "leg" is one of the two equivalent non-parallel sides . The base angles of an isosceles trapezoid are equal. The center line or median of the trapezoid is parallel to the base and its length is half the total length of the base. We have given that,

length of side BO = 12

length of side TA = 6

The length of Median = 1/2(12+6)

The scale factor of the dilation of the triangle ABC is equal to 2.5.

We know that the triangles ABC and A'B'C' are similar.

The scale factor of the dilution is given by -

scale factor = measure of A'B' / measure of AB.

Now, let's find the measure of AB and the measure of A'B' from the graph given below, using the distance formula as follows-

The distance formula is = [tex]\sqrt{(y_{2} - y_{1})^{2} + (x_{2} - x_{1})^{2}}[/tex]

Hence, the distance AB =[tex]\sqrt{(2-2)^{2} + (2-0)^{2}}[/tex]

                                       = [tex]\sqrt{(0)^{2} + (2)^{2}}[/tex]

                                       = [tex]\sqrt{2^{2}}[/tex]

                                       = 2 units

Similarly, we can find the distance A'B'

The distance A'B' = [tex]\sqrt{(-1+1)^{2} + (1+4)^{2}}[/tex]

                             = [tex]\sqrt{(0)^{2} + (5)^{2}}[/tex]

                             = [tex]\sqrt{(5)^{2}}[/tex]

                             = 5 units

Now, the scale factor = measure of A'B' / measure of AB

                                       = 5/2

                                       =2.5

Thus, the scale factor of the dilation is 2.5.

1. The expression can be simplified as follows: 4 × 5 – 32 × 2 ÷ 6 = 20 – 16 ÷ 6 = 20 – 2 = 18.

2. The expression can be simplified as follows: -2(-9 + 3) = -2(-6) = 12.

3. To solve this equation, we need to isolate the variable a. We can do this by dividing both sides of the equation by -13: -a/13 = 18. Dividing both sides of the equation by -13 gives us a = -18 * 13 = -234.

4. To solve this equation, we need to isolate the variable x. We can do this by moving all terms involving x to one side of the equation and all constants to the other side. This gives us: 7 = 5x + 3(x – 2). We can then distribute the 3 to get 7 = 5x + 3x – 6. Combining like terms, we get 7 = 8x – 6, which we can solve by adding 6 to both sides to get 13 = 8x. Dividing both sides of the equation by 8 gives us x = 13/8.

5. To solve this equation, we need to isolate the variable w. We can do this by moving all terms involving w to one side of the equation and all constants to the other side. This gives us: 11w + 2(3w - 1) = 15 w. We can then distribute the 2 to get 11w + 6w - 2 = 15w. Combining like terms, we get 17w - 2 = 15w, which we can solve by adding 2 to both sides to get 17w = 15w + 2. Subtracting 15w from both sides gives us 2w = 2, which we can solve by dividing both sides by 2 to get w = 1.

6. N' is the complement of the set N. This means that N' contains all elements that are not in the set N. Since the set N contains all factors of 18, N' will contain all natural numbers less than 20 that are not factors of 18. Some elements of N' are 1, 2, 4, 5, 7, 8, 11, 13, 14, 16, and 17.

7. The solution to the inequality 17 - 2a ≤ 29 is all values of a that satisfy the inequality. To find these values, we can first subtract 17 from both sides of the inequality to get -2a ≤ 12. Dividing both sides of the inequality by -2 gives us a ≥ -6. This means that the solution is the set of all values of a that are greater than or equal to -6. This solution can be represented on a number line

8.To solve the inequality 17 – 2a ≤ 29, we first need to isolate the variable on one side of the inequality. To do this, we need to subtract 17 from both sides, which gives us -2a ≤ 12. Dividing both sides by -2, we get a ≥ -6. To graph this inequality, we can use a number line. We would draw a solid line at -6 and shade the region to the right of the line, since a is greater than or equal to -6.

9. To solve the inequality 12c + 6 > 9c – 15, we first need to isolate the variable on one side of the inequality. To do this, we need to subtract 9c from both sides, which gives us 3c + 6 > -15. Next, we need to add 15 to both sides, which gives us 3c + 21 > 0. Finally, we can divide both sides by 3 to get c > -7. To graph this inequality, we can use a number line. We would draw a solid line at -7 and shade the region to the right of the line, since c is greater than -7.

3 enlargement is the scale factor of the dilation.

What is dilation?

resizing an object is accomplished through a change called dilation. The objects can be enlarged or shrunk via dilation. A shape identical to the source image is created by this transformation. The size of the form does, however, differ. A dilatation ought to either extend or contract the original form. The scale factor is a phrase used to describe this transition.

The scale factor is defined as the difference in size between the new and old images. An established location in the plane is the center of dilatation. The dilation transformation is determined by the scale factor and the center of dilation.

While virtually all time series exhibit a random​ component, not all time series exhibit other components is a true statement.

It's accurate to say that while almost all time series show a random component, not all time series show additional components.

A time series is a collection of observations of discrete data points gathered over a period of time by repeated measurements. For instance, calculating the quantity of retail sales for each month of the year would be a time series. This is because sales income is consistently and precisely measured at regular times. Data collected once or irregularly are not time series data.

A time series observation can be divided into three categories: trend (long-term direction), seasonal (systematic, calendar-related motions), and irregular (unsystematic, short term fluctuations).

A time series is a group of data points that have been arranged chronologically in mathematics. Typically, a time series is a sequence that was captured at many equally spaced intervals in time. As a result, it is a collection of discrete-time data.

The first term of the geometric progression= 1/5

What is common ratio?

In a geometric sequence, ratio of each term to its immediately preceding term is always constant and is known as common ratio.

Given:

The second term = 3/10

The sixth term = 243/ 160

The formula for the nth term of geometric sequence is given by

an = a1 r^(n-1 ) , a1 = first term , r= common ratio

Substitute n=2

a2 = a1 r^(2-1 ) ..................(1)

3/10 = a1* r

Substitute n=6

243 / 160 = a1 r^5 ..............(2)

dividing equation 2 by 1 , we get

r^4 = 5.0625

=> r = 1.5
