Answer:

Step-by-step explanation:

Here,

Said that x and y vary inversely ,

So,

Then an increase in x causes corresponding decrease in y and vice-versa then to find the constant k will be:

Hence,

Here y = 8 and x = 10

So their constant will be,

x × y = k

=> k = 8 × 10

=> k = 80

The rate of change of the function is 3.25.

The percentage change in value over a predetermined period of time is mathematically described by the term "rate of change."

In general, the formula for rate of change is: R = (D2 - D1)/T. where: R = rate of change.

Given:

X l Y

0 l -4

4 l -9

8 l -14

12 l -19

So, the rate of change

= (-4 - (-9)) / (4-0)

= (4+ 9) / 4

= 13 / 4

= 3.25

Thus, the rate of change is 3.25

Answer:

Subtract 10

Step-by-step explanation:

The first option, "take the ones digit", is obviously incorrect because the ones digit of 9 is not -1. The second one is incorrect because you are dividing by 2 and then adding 5. Dividing odd numbers by 2 will give you a decimal and a decimal plus an integer (the integer is 5 in this case) will still be a decimal (provided that the decimal is not an integer as well). However, both of the outputs are integers, so we know that the second one is wrong. The third one is wrong as well because 9 / 3 = 3, not -1. The last one is correct because 15 - 10 = 5 and 9 - 10 = -1.

LP is the length of one of the equal sides of the rhombus. Since LN is the length of the other equal side and LP is half the length of LN, LP is 14 cm.

In a rhombus, the diagonals bisect each other at a right angle. Given that LN is 28 cm, we can conclude that LP is half the length of LN since the diagonals bisect each other.

Therefore, LP = 28 cm / 2 = 14 cm.

In a rhombus, the diagonals divide the shape into four congruent right-angled triangles. Each triangle has two equal sides, which are the sides of the rhombus, and a hypotenuse, which is one of the diagonals. Since the diagonals bisect each other at a right angle, the triangles formed are also congruent.

This means that the average cost of selected automobiles has increased by 16% between the two years.

Given data: The average cost of selected automobiles in 2019 = $15,000

The average cost of selected automobiles now (current year) = $17,400

Let's calculate the rate of increase in the average cost of the automobile between the two years.

To find the rate of increase, use the following formula;
rate of increase = increase in value / original value * 100

To get the increase in the value of selected automobiles, subtract the current year's average cost of selected automobiles from the previous year's average cost of selected automobiles.

i.e. increase in value = current year's average cost - previous year's average cost

= $17,400 - $15,000

= $2,400

Now put the values in the formula to get the rate of increase;

rate of increase = increase in value / original value * 100

= 2400 / 15000 * 100

= 16

Therefore, the rate of increase for selected automobiles between the two time periods is 16%.

It's essential to note the rate of increase or decrease in the value of products or services. It helps in decision making, future predictions, etc.

The above question deals with finding the rate of increase in the cost of selected automobiles. To get the rate of increase, the formula rate of increase = increase in value / original value * 100 is used.

To get the increase in the value of selected automobiles, subtract the current year's average cost of selected automobiles from the previous year's average cost of selected automobiles. i.e. increase in value = current year's average cost - previous year's average cost.

The value of selected automobiles was $15,000 in 2019, and now it is $17,400.

Now, the rate of increase in the average cost of automobiles can be found using the formula rate of increase = increase in value / original value * 100.

Put the values in the formula to get the rate of increase.

Therefore, the rate of increase for selected automobiles between the two time periods is 16%.

It indicates that if a person had bought an automobile in 2019 for $15,000, he has to pay $17,400 for the same automobile now.

The value of x is x = 9/4. The equation 2xc = d as follows: 2xc = d2x * 1/2 = 9/22x = 9/2 * 2x = 9/4

The equation 2xc = d and 2x + 1 = 9 are similar in that they are both linear equations and involve the variable x.

However, they are different in that they have different constants and coefficients.

How to use 2xc = d to solve 2x + 1 = 9? To use 2xc = d to solve 2x + 1 = 9, you first need to rewrite 2x + 1 = 9 in the form 2xc = d.

To do this, you need to isolate x on one side of the equation. 2x + 1 = 9

Subtract 1 from both sides2x = 8. Divide both sides by 2x = 4Now, we can write 2x + 1 = 9 as 2x * 1/2 = 9/2.

Therefore, we can see that this equation is similar to 2xc = d, where c = 1/2 and d = 9/2.

We can use this relationship to solve for x in the equation 2xc = d as follows: 2xc = d2x * 1/2 = 9/22x = 9/2 * 2x = 9/4 Therefore, x = 9/4.

The selling price of a sum of book and notebook is $8

Let x represent the price of a notebook

Let y represent the price of a book

2x+ 5y= 34.......equation 1

5x+2y= 22.........equation 2

Solve using the elimination method

Multiply equation 1 by 5 and equation 2 by 2

10x + 25y= 170

10x + 4y= 44

Subtract both equation

21y= 126

y= 126/21

y= 6

Substitute 6 for y in equation 1

2x + 5y= 34

2x + 5(6)= 34

2x + 30= 34

2x= 34-30

2x= 4

x= 4/2

Count is incremented by 1 before returning the result because we want to count the number of trials needed to achieve the first success.

To create a Geometric random variable with a probability of success equal to p, you can use the following algorithm:

Initialize a counter variable, let's call it count, to 0.

Generate a random number between 0 and 1, let's call it rand_num.

Set the initial probability of success, prob_success, to p.

While rand_num is greater than prob_success, do the following steps:

Increment count by 1.

Generate a new rand_num between 0 and 1.

Update prob_success by multiplying it with (1 - p).

Return count + 1 as the generated Geometric random variable.

This algorithm works by repeatedly generating random numbers until a success occurs. Each time a failure occurs (when rand_num is greater than prob_success), the probability of success is updated to account for the remaining trials.

Note that count is incremented by 1 before returning the result because we want to count the number of trials needed to achieve the first success.

To determine the type of function, we would compare the y values. If the ratio of consecutive y values is the same, then the function is exponential. We have

2/1 = 4/2 = 8/4 = 2

Thus, it is an exponential function. The general formula for an exponential function is

y = ab^x

We would find a and b

Substituting x = 0 and y = 1 into the formula, we have

1 = ab^0

1 = a

Substituting x = 1 and y = 2 into the formula, we have

2 = ab^1

2 = ab

Substituting a = 1 into 2 = ab, then

2 = 1 * b = b

By substituting a = 1 and b = 2 into the original formula, the equation would be

y = 2^x

Let me guess. You got this from Edmentum.

You use a compass to draw an arc (or a full circle). The radius must be kept the same so that you can copy the length of the segment properly. If the compass could move freely, then it is unlikely the arc will be a piece of a circle, and rather some squiggly curve. So this is why the compass width must be locked into place.

To evaluate (6.7 * 10⁻¹⁶) - (8.2 * 10⁻¹⁷), Celia should Subtract the numbers to get the difference.

Step 1: Make the powers of 10 the same To make the powers of 10 the same, adjust the second number, which is 8.2 × 10⁻¹⁷, to have the same power of 10 as the first number, which is 6.7 × 10⁻¹⁶.

Since 10⁻¹⁷ is a smaller power of 10 than 10⁻¹⁶, we must multiply the numerator and denominator of 8.2 × 10⁻¹⁷ by 10 to obtain an equivalent value that has the same power of 10 as the first number. Therefore, we get;8.2 × 10⁻¹⁷ = (8.2 × 10⁻¹⁷) × (10 / 10)

= 82 × 10⁻¹⁸.

Step 2: Subtract the numbers Now that we have the same power of 10 in both numbers, we can subtract them. 6.7 × 10⁻¹⁶ - 82 × 10⁻¹⁸ = 6.7 × 10⁻¹⁶ - 0.0082 × 10⁻¹⁶ = 6.6918 × 10⁻¹⁶.
