Using the inscribed angle theorem, the value of x is: 9.
What is the Inscribed Angle Theorem?Note that an intercepted arc is regarded as part of the circumference of a circle, which is between a chord and a tangent. Thus, based on the inscribed angle theorem, the inscribed angle measure = 1/2(the intercepted arc measure).
So, we would have:
m∠DEF = 1/2(arc DE)
m∠DEF = 4x + 19
arc DE = 360 - (28x - 2) = 360 - 28x + 2
arc DE = 362 - 28x
Plug in the values
4x + 19 = 1/2(362 - 28x)
Solve for x
2(4x + 19) = 362 - 28x
8x + 38 = 362 - 28x
8x + 28x = 362 - 38
36x = 324
x = 324/36
x = 9

What is the quotient when 2 x 2 + 4 x – 14 is divided by 2 x
The quotient when 2x² + 4x – 14 is divided by 2x is [tex]x + 2 - \frac{7}{x}[/tex] .
What is Quotient in Division?When two numbers are divided by each other, the result is known as a quotient. For instance, when we divide 8 by 2, the result will be 2, where 2 is the quotient.
As we know division is a mathematical operation that involves dividing items into equal groups. It is represented by the symbol (÷). When we divide a number, the result we ultimately get is the quotient.
Here we have
2x² + 4x – 14 is divided by 2x
=> [tex](2x^{2} + 4x - 14) \div {2x}[/tex]
=> [tex]\frac{(2x^{2} + 4x -14)}{2x}[/tex]
Take 2x as common
=> [tex]\frac{2x(x + 2 - \frac{7}{x} )}{2x}[/tex]
=> [tex]x + 2 - \frac{7}{x}[/tex]

A farmhouse shelters 23 animals. Some are goats and some are ducks. Altogether there are 58 legs. How many of each animal are there?
There are 6 goats and 17 ducks present in the farmhouse
How to calculate the number of goats and ducks ?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
x= 23-17
x= 6
Hence there are 6 goats and 17 ducks in the farmhouse shelter

The doctor has ordered a 5% saline solution to be prepared. How many grams of pure drug will be needed to make 115 mL of solution at the 5% strength?
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 rode her bike about 2 ½ miles in ¼ hour. What was her average speed in miles per hour?
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.

What is the total amount of money Peter earns raking lawns in August and September?The total amount of money Peter earns from raking lawns in August and September can be found by solving the equation 5 x 8 + 10 = m, where m represents the total money earned.
Here,
In this equation, 5 represents the number of lawns Peter raked in August, 8 represents the amount he earns for each lawn, and 10 represents the amount he earned from raking lawns in September.
When this equation is solved, the result is m = 55, meaning that Peter earned a total of $55 from raking lawns in August and September.
This can be seen by multiplying 5 times 8, which is 40, and then adding 10, which brings the total to 55.
Therefore, the total amount of money Peter earns from raking lawns in August and September is $55.

Find the differential of each function. (a) y - x^2 sin 8x
The differential of the function y - x² sin 8x with respect to x is dy/dx - 2x sin 8x + 8x² cos 8x
To find the differential of the function y = x² sin 8x, we can use the standard notation dy/dx which represents the rate of change of y with respect to x.
To calculate dy/dx, we need to use the product rule, which states that the derivative of the product of two functions is the derivative of the first function times the second function plus the first function times the derivative of the second function.
Let z be the given function,
z= y - x² sin 8x
The derivative of x² is 2x

How to solve composite function?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

(f − g)(x) = 3x + 12
(f − g)(x) = 3x + 16
(f − g)(x) = 13x + 12

The function that represents how many more texts that were sent this week than last week is: B. (f − g)(x) = 3x + 16.
How to Evaluate Functions?To find the value of a given functional expression, we have to apply the basic knowledge of how to solve algebraic expressions.
For example, if we are given that (f - g)(x), it means we are to subtract the function g(x) from f(x). That is (f - g)(x) = f(x) - g(x).
Given the following functions:
Number of texts sent this week is represented as the function, f(x) = 8x + 14
Number of texts sent last week is represented as the function, g(x) = 5x - 2.
Number of texts that were sent this week than last week = (f - g)(x)
(f - g)(x) = (8x + 14) - (5x - 2)
(f - g)(x) = 8x + 14 - 5x + 2

If the mean of this data is 95, find the missing data. 103, 99, 90, 86, 105, 96, ___
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.

check:
The solution to the equation -9 = 6m + 15 is m = -4.
What is the solution to the given equation?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

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.
