Step-by-step explanation:

Formula: An=8/5x5(4)

The solution of the function is as follows:

(f o g)(x) = 16x² + 17x + 1

(g o f)(x) = 4x² + 36x + 1

Composite functions are when the output of one function is used as the input of another.

Therefore, let's solve the composite functions as follows:

f(x) = x² + 9x

g(x) = 4x + 1

Therefore,

(f o g)(x) = f(g(x))

Therefore,

f(g(x)) = (4x + 1)² + 9x = (4x + 1)(4x + 1) + 9x = 16x² + 4x + 4x + 1 + 9x = 16x² + 17x + 1

(g o f)(x) = g(f(x))

g(f(x)) = 4(x² + 9x) + 1 = 4x² + 36x + 1

Therefore,

(f o g)(x) = 16x² + 17x + 1

(g o f)(x) = 4x² + 36x + 1

There are 6 goats and 17 ducks present in the farmhouse

Let x represent the number of goats

Let y represent the number of ducks

x + y= 23....equation1

Goats have 4 legs and ducks have 2 legs

4x + 2y= 58.......equation 2

From equation 1

x + y= 23

x= 23-y

Substitute 23-y for x in equation 2

4(23-y) + 2y = 58

92- 4y + 2y= 58

92-2y= 58

-2y= 58-92

-2y= -34

y- 34/2

y= 17

Substitute 17 for y in equation 1

x + y= 23

x + 17= 23

1)  A sequence of real numbers is an ordered list of real numbers where each number in the list is assigned a specific position or index, usually denoted by n. The sequence is denoted by {xn} n>n0, where xn represents the nth term of the sequence and n ranges from 0 to infinity.

2)An example of a sequence of rational numbers is {2, 1.5, -0.5, -1.25, ...}, where each term in the sequence is a rational number.

3) The recursive definition of the summation of ai is a mathematical formula that defines the nth term of the summation in terms of the previous terms. It is typically denoted as:

∑(i=1)^ni = a1 + (a2 + (a3 + ....(an-1 + an)...)),

Where a1 is the first term of the summation, a2 is the second term, and so on and so forth. This recursive definition is used to calculate the nth term of the summation by adding the previous term to the current term. It is generally used in mathematical induction and recursion.

4)The associative property of summation notation states that the order in which the summation is performed does not affect the final result. In other words, for any three indices a, b, and c, and any sequence of numbers {xn}, the following equation holds:

∑(a=b)c xn = ∑(a=c)b xn = ∑(a=b)c xn

This property allows us to group the terms in a summation in different ways without changing the final result.

5) The translation invariance property of summation notation states that the value of a summation is unchanged when the index of summation is translated (shifted) by a constant value. In other words, for any indices a and b, any constant k, and any sequence of numbers {xn}, the following equation holds:

∑(a=b)xn = ∑(a+k=b+k)xn

This property allows us to shift the index of summation without affecting the final result of the summation.

Answer:

(115 x 5) / 100 = 0.575 grams of the pure drug.

Step-by-step explanation:

To make a 5% solution, the concentration of the pure drug is 5 grams per 100 mL of solution.

To find the amount of pure drug needed for a specific volume, such as 115 mL, you can use the formula:

(volume of solution x concentration of pure drug) / 100

So in this case:

(115 x 5) / 100 = 0.575 grams of the pure drug.

This calculation shows that 0.575 grams of the pure drug would be needed to make 115 mL of a 5% solution.

Answer:

5.75 g

Step-by-step explanation:

First calculate 5% of the total amount of solution, 115 ml:

[tex]\implies \sf 5\%\;of\;115\;ml=\dfrac{5}{100} \times 115=5.75\;ml[/tex]

As we have not been told any information about the drug, assume the standard equivalent that 1 ml equals 1 gram.  Therefore, the amount of pure drug needed to make 115 ml of solution at the 5% strength is 5.75 g.

Nya's average speed was 10 miles per hour.

What is the speed, distance, and time?

Speed, distance, and time are related concepts in physics that are used to measure and describe motion.

Speed is a measure of how fast an object is moving. It is typically measured in units of distance per unit of time, such as miles per hour or kilometers per hour. Speed can be calculated using the formula:

Speed = Distance / Time

To find Nya's average speed in miles per hour, we need to divide the distance she traveled by the time it took her to travel that distance.

Average speed = distance/time

We know that Nya rode her bike 2 ½ miles in ¼ hour. To use these measurements in the formula, we need to convert the units to the same unit of measurement. In this case, we need to convert the distance to miles and the time to hours.

Average speed = (2.5 miles) / (0.25 hour)

To find out the speed in miles per hour, you need to multiply by the conversion factor 1 hour/60 minutes, so

Average speed = (2.5 miles) / (0.25 hour) * (1 hour/60 minutes)

Average speed = (2.5 miles) / (0.25 hour) * (4)

Average speed = 10 miles per hour.

Hence, Nya's average speed was 10 miles per hour.

Answer:

Answer:

Step-by-step explanation:

The solution to the equation -9 = 6m + 15 is m = -4.

Given the equation in the question;

-9 = 6m + 15

Rewrite the equation as 6m + 15 = -9

Move all terms not containing m to the right side of the equation by subtracting 15 from both sides

6m + 15 - 15 = -9 - 15

6m = -9 - 15

Add -9 and -15

6m = -24

Divide both sides by 6

6m/6 = -24/6

m = -24/6

m = -4

Solution check

Plug m = -4 into the equation and check

-9 = 6m + 15

-9 = 6( -4 ) + 15

-9 = -24 + 15

-9 = -9

Correct.

Therefore, the numerical value of m is -4.

We have discussed the general strategy for solving an equation of the form x/a = b.

What is an equation?

An equation is a mathematical statement that shows that two expressions are equal. An equation is composed of two sides, separated by an equal sign (=), with each side containing one or more variables, numbers, and/or mathematical operations.

The general strategy for solving an equation of the form x/a = b is to:

Multiply both sides of the equation by a, in order to cancel out the fraction on the left side. This will isolate the variable x on one side of the equation.

Simplify the equation by combining like terms if necessary.

Check the solution by substituting it back into the original equation and verifying that it makes the equation true.

For example, consider the equation x/2 = 4

Multiply both sides by 2: x/2 * 2 = 4 * 2

x = 8

To check the solution, substitute it back into the original equation: x/2 = 4, 8/2 = 4. The equation is true, so x = 8 is the correct solution.

It's important to keep in mind that when solving equations, it is important to follow the order of operations, and also to be careful when dividing or multiplying by zero.

Answer: The missing value is 86

Step-by-step explanation: The mean of a data set is the same as the average. The formula for mean is the sum of the data values/(the number of data values). Right now there are only 6 data values and we are looking for a seventh. If we sum the 6 current values and divide by 6, we get a data set with a mean of 96.5. We need a lower mean. The data set we need has 7 points so the sum of all 7 points should be 7(95) since if we divide 7(95) by the number of points which is 7, we get 95 which is the mean we want. 7(95) is 665. We can subtract the sum of the current 6 points from 665 to find the value we want.

The cost of the class would be $740 x 3 = $2220. If you were to work instead, at $10 per hour for 10 hours per week for 15 weeks, you would earn $1500. So, the net cost of the class would be $2220 - $1500 = $720.

In general, a college degree can lead to higher earning potential and greater career opportunities, so in most cases, it can be considered a worthwhile investment. However, the decision to take a particular class should be based on individual circumstances and goals. If the class is relevant to your future career aspirations and you can afford the cost, it may be a good investment. However, if the class is not directly related to your career goals, or you are not able to afford the cost, it may not be worth it.
