In the given set of data, 4/5 is the constant of proportionality in the proportional relationship.

When two or more parameters are either directly or indirectly proportional to one another, the relationship is written as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables. The proportionality constant, k, is defined as follows.

The ratio of two proportional values at a constant value serves as the definition of the proportionality constant. When the product or ratio of two variables yields a constant, the relationship between the two is proportional. By comparing the ratio of the two specified quantities, we can calculate the value of the proportionality constant. A direct variation or an inverse variation of this relationship are both possible.

Given

2 : 5/2

2 = (k)5/2

also

3 : 15/4

3 = (k)15/4

This gives us

k = 2 × 2/5

k = 4/5

k = 3 × 4/15

k = 4/5

Thus, In the given set of data, 4/5 is the constant of proportionality in this proportional relationship.

The additive inverse of -13 7/8 is +13 7/8.

The additive inverse of a number is the number that, when added to the original, equals zero. The additive inverse of -13 7/8 can be found by turning the sign of the original number into its opposite, which would be +13 7/8. This can be expressed mathematically using the formula a + (-a) = 0, where a is the original number.

When -13 7/8 is added to +13 7/8, the result is 0. This can be seen by calculation: -13 7/8 + 13 7/8 = -13 7/8 + 8/8 + 5/8 = -5/8 + 8/8 = 3/8 + 8/8 = 11/8 + 8/8 = 19/8 + 8/8 = 27/8 + 8/8 = 35/8 + 8/8 = 43/8 + 8/8 = 51/8 + 8/8 = 59/8 + 8/8 = 67/8 + 8/8 = 75/8 + 8/8 = 83/8 + 8/8 = 91/8 + 8/8 = 99/8 + 8/8 = 107/8 = 0.

The number 9550000 can be arranged in a total of 8!/(4!4!) = 70 different ways.

Digits are numerals or numbers used for counting, measuring, and representing quantities. They are the building blocks of mathematics, and are used to express amounts, relationships, and orders of magnitude. Digits are also used in computers and other digital devices to store and communicate information.

The 8 digits of 9550000 can be arranged using the formula for permutation: nPr = n!/(n-r)!

In this case, n = 8 and r = 8. So, the number of permutations of the 8 digits of 9550000 will be 8!/(8-8)! = 8!/(0!) = 8! = 40320.

However, we need to account for the fact that there are 4 zeros in the number 9550000. To do this, we need to divide the number of permutations by 4! (factorial of 4) to account for the 4 identical digits.

Therefore, the total number of ways the digits in the number 9550000 can be arranged is 40320/4! = 70.

Step-by-step explanation:

a). The sequence as represented in question a). is not an arithmetic sequence and hence, does not have a common difference.

b). The sequence formed by recording the daily odometer reading of a car after driving 15 miles each day does not have a negative common difference.

It follows from the task content that the sequence which has a negative common difference be determined.

It follows that the common difference, by definition is the difference between successive terms a (n) of the sequence.

Therefore, common difference is usually given by; a (n) - a (n-1).

a). Since the given sequence is; 64, 32, 16, 8, ....

Since The common difference is; 32 - 64 ≠ 16 - 32 ≠ 8 - 16.

Hence, the sequence does not have a common difference and hence, is not an arithmetic sequence.

b). For a sequence involving the daily odometer reading of a car after driving 15 miles every day.

It follows that the recursive function for such a sequence would take the form; a (n) = a (n-1) + 15.

By comparison with the standard recursive function for arithmetic sequences, a (n) = a (n-1) + 15, it follows that the common difference, d = 15.

The value of CE in the segment is 30 units.

The value of x in the segment is 1 units.

A line segment is bounded by two distinct points on a line. Therefore, point D is located on the segment CE. Hence,

CD = 24 and DE = x

CE = 5x

Therefore, the measurement of the segment CE can be found as follows:

CE = CD + DE

5x = 24 + x

5x - x = 24

4x = 24

divide both sides of the equation by 4

x = 24 / 4

x = 6

Distance is a measure of how far an object has traveled from a starting point. Displacement is the change in position from the starting point.

It is the total distance an object has moved and is the sum of all the displacements an object has made. The formula for calculating distance is distance = speed x time. For example, if a car has traveled at a speed of 50 km/h for 4 hours, then the distance traveled is 200 km (50 km/h x 4 h = 200 km).

Displacement is the change in position from the starting point. It is the shortest distance between the starting point and the final point and does not take into account the direction of motion. The formula for calculating displacement is displacement = final position – initial position. For example, if a car starts at point A and travels to point B, the displacement is the distance between A and B (B – A).
