Answer:
Step-by-step explanation:
We have, C(x) = 0.005x3 – 0.02x2 + 30x + 5000
Clearly, the marginal cost, MC (x) = \(\frac{d}{d x}\)C(x)
= \(\frac{d}{d x}\)(0.005x3 – 0.02x2 + 30x + 500)
= 0.005 × 3x2 – 0.02 × 2x + 30 + 0
= 0.015x2 – 0.04x + 30
Now, marginal cost when 3 units arei produced
MC(3)= 0.015(9) – 0.04(3) + 30
= 0135 – 0.12 + 30= 30.015

Once Emily's bank account fails below $0.
her bank charges her $3 each day until
she makes a deposit to reach a positive
balance. If the balance in her account is
$32 and she makes a $60 purchase, what is
the balance in her account after 7 days if
she does not make a deposits
========================================================
Explanation:
Her original balance starts off at $32. After making the $60 purchase, her balance becomes 32-60 = -28 dollars. We wouldn't say 60-32 = 28 because the expense is larger than her balance.
Being in the negative territory means Emily is in debt to the bank, until she can get her balance back to $0 or higher. Since they charge her $3 a day for being in the negative area, and her balance is like this for 7 days, then they charge a total of 7*3 = 21 dollars.
So the -28 will drop to -28-21 = -49 dollars
If she doesn't want any more charges done, she needs to deposit $49 or more into the account on the 8th day.

Rachel is arranging 12 cans of food in a row on a shelf. She has 8 cans of beets, 3 cans of corn, and 1 can of beans. In how many distinct orders can the cans be arranged if two cans of the same food are considered identical (not distinct)?
Given:
Total number of food cans = 12
Cans of Beets = 8
Cans of corn = 3
Can of beans = 1
To find:
How many distinct orders can the cans be arranged if two cans of the same food are considered identical.
Solution:
To find the distinct ways arrangement, we have a formula:
[tex]\text{Number of distinct ways}=\dfrac{n!}{r_1!r_2!...r_k!}[/tex] ...(i)
Where, n is the number of objects and [tex]r_1,r_2,...,r_k[/tex] are repeated objects.
Total number of food cans is 12. So, [tex]n=12[/tex].
She has 8 cans of beets. So, [tex]r_1=8[/tex]
She has 3 cans of corns. So, [tex]r_2=3[/tex]
She has 1 can of beans. So, [tex]r_3=1[/tex]
Substituting these values in (i), we get
[tex]\text{Number of distinct ways}=\dfrac{12!}{8!3!1!}[/tex]
[tex]\text{Number of distinct ways}=\dfrac{12\times 11\times 10\times 9\times 8!}{8!\times 3\times 2\times 1\times 1}[/tex]
[tex]\text{Number of distinct ways}=\dfrac{11880}{6}[/tex]
[tex]\text{Number of distinct ways}=1980[/tex]
Therefore, the number of distinct orders to arrange the cans is 1980.

Answer: 3 hours and 45 minutes
Step-by-step explanation:
We can see that the first clock is at 10:30 am (the short hand is the hour, and it's pointing at 10, and the long hand is the minutes, and it's pointing at 6, which would mean 30 minutes since you multiply 6 by 5)
The second clock is at 2:15 pm using the same logic.
12:00 is when the time changes from am to pm. So, find the time difference from 10:30 am to 12:00
Subtract 30 from 60, and we get thirty, so after 30 minutes, the time will change from 10:30 to 11:00. Then we have 1 hour from 11:00 to 12:00. This means that from 10:30 to 12:00, the time spent is 1 hour and 30 minutes.
Finally, we add 2 hours and 15 minutes, since that's the second time.
Add both those times together:
1 hour and 30 minutes plus 2 hours and 15 minutes = 3 hours and 45 minutes.
Answer:
4 hours and 45 minutes
Step-by-step explanation:
the first clock shows 10:30am and the second clocks shows to be at 2:15pm
which you count by hours is 10,11,12,1,2 so you went but 4 hours and 45 minutes

Math Subject: Symmetry.
Question is attached below.
The term "line of symmetry" refers to the fictitious axis or line that you fold a figure along to create its symmetrical halves.
What is Symmetry?A definition of symmetry states that whether one form is moved, rotated, or flipped, it looks precisely like the other shape. Just fold the paper, draw one-half of the heart at the fold, then cut it out to discover that the second half precisely matches the first half when you are instructed to cut out a "heart" from a sheet of paper. The heart-shaped carving is an illustration of symmetry.
Symmetry is defined in mathematics as "a mirror image." Symmetry is the property of an image that remains unchanged after a form has been rotated or flipped. There are patterns in it. In daily life, you may have heard the word "symmetrical" frequently. One half of a thing is the mirror image of the other half, which is a balanced and proportionate likeness. Asymmetrical refers to a form that is not symmetrical. In nature, architecture, and the arts, symmetrical things are all around us.
The term "line of symmetry" refers to the fictitious axis or line that you fold a figure along to create its symmetrical halves. In essence, it splits one thing into two mirror images. The symmetry line may run vertically, horizontally, or diagonally. There might be one or many symmetry lines.

Answer:
1. Choose Your Shape: Start with a shape that you want to create a line of symmetry for. It could be a simple shape like a square, rectangle, or triangle.
2. Draw the Shape: Draw the shape neatly on a piece of paper using a pencil.
3. Identify the Line of Symmetry: Decide where you want to place the line of symmetry. This line should divide the shape into two equal halves.
4. Draw the Line of Symmetry: Draw a straight line through the center of the shape, from one side to the other. Use a ruler to ensure the line is straight and passes through the center.
5. Create the Mirror Image: To create the mirror image on the other side of the line, imagine that the line is a mirror. Reflect each point on one side of the line to the other side while maintaining the same distance from the line. You can also use a ruler or straightedge to guide you as you draw.
6. Check for Symmetry: Carefully examine both sides of the line to make sure they are mirror images of each other. The distances and angles should match.
7. Finalize the Drawing: Once you're satisfied with the symmetry, trace over your pencil lines with a pen or darken them to make your drawing more prominent.
8. Erase Construction Lines: Gently erase any construction lines or guidelines you drew in the earlier steps.

As per the given percentage of tax and discount, the final cost of the milk is $3.8186
The term percentage in math is known as a relative value indicating hundredth parts of any quantity.
Here we have given that You buy a gallon of milk that costs $3. 50.
And here we also know that the milk is discounted for 10% off.
Here we have also have to pay tax of 6. 25% on the discounted price.
First we have to calculate the discounted prices, that can be obtained by the following calculation,
=> 3.50 - [3.50 x 10/100]
=> 3.50 - [3.50 x 0.1]
=> 3.50 - 0.35
=> 3.15.
Now, we have to calculated the tax for the price of the milk,
=> 3.50 + [3.50 x 6.25/100]
=> 3.50 + [3.50 x 0.0625]
=> 3.50 + 0.2186

point. From the time it is released it will bounce at a rate of 3
cycles per second.
a. Draw a graphical representation and give the equation
involving the situation.
b. What is the displacement of the spring after 2.5
seconds?
a. The graphical representation of the oscillation of the weight suspended from a spring is a sine wave, with the displacement of the weight on the y-axis and time on the x-axis. The equation involving the situation would be y = Asin(2pift + phi) where A is the amplitude of the oscillation (3 cm in this case), f is the frequency of oscillation (3 cycles per second in this case), t is the time elapsed since the weight was released, and phi is the phase offset (0 in this case).
b. To find the displacement of the spring after 2.5 seconds, we can substitute 2.5 seconds for t in the equation: y = Asin(2pift + phi) = 3sin(2pi32.5 + 0) = 3sin(15pi) = 3*0 = 0 cm. So the displacement of the spring after 2.5 seconds is 0 cm.

1. What is the unit of measurement for speed using the metric system?
Answer:
meter per second(m/s)
Answer:
Hey there! The metric system has a unit called meters per second for measuring speed. It's abbreviated as m/s and it's used to measure how far something travels in a certain amount of time. For example, if something goes 50 meters in 10 seconds, its speed would be 50 m/s / 10 s = 5 m/s. There are other units for measuring speed too, like kilometers per hour (km/h) and centimeters per second (cm/s). It just depends on what you're measuring and how precise you need to be.
________________________________________________________
How do things like distance and time affect the speed of an object?Well, speed is all about how far something goes in a certain amount of time. So if you increase the distance traveled or decrease the time it takes to travel that distance, the speed will increase. On the other hand, if you decrease the distance traveled or increase the time it takes to travel that distance, the speed will decrease.
Why is it important to measure and calculate speed in certain situations?There are all sorts of situations where knowing the speed of something is important. For example, if you're driving a car, it's important to know how fast you're going so you can stay safe and follow the speed limits. In sports, measuring speed can help coaches and players improve their performance. And in science, measuring the speed of light or other phenomena can help us better understand the world around us. So as you can see, speed is a pretty important concept!

Sample data consist of 46 randomly selected observations with a mean of 4. 23 milliroentgens and a standard deviation of 1. 91 milliroentgens. Test the claim that the machine gives a radiation dose lower than the maximum on the label
There is very strong evidence to reject the null hypothesis, and to conclude that the machine gives radiation doses lower than the maximum on the label.
What is hypothesis testing?Hypothesis testing is a statistical method used to test a claim or a hypothesis about a population parameter, based on a sample of data. The goal of hypothesis testing is to determine whether there is enough evidence in the sample data to support or reject a claim about a population.
What is t-test?A t-test is a type of statistical hypothesis test that compares the mean of a sample to a known population mean. There are different types of t-tests, depending on the design of the study and the number of samples being compared.
To test the claim that the machine gives a radiation dose lower than the maximum on the label (5.00 milliroentgens), we can use a one-sample t-test. A one-sample t-test compares the mean of a sample to a known population mean (in this case, the maximum on the label). The null hypothesis for this test is that the mean radiation dose given by the machine is equal to or greater than the maximum on the label (5.00 milliroentgens). The alternative hypothesis is that the mean radiation dose given by the machine is less than the maximum on the label.
The test statistic for a one-sample t-test is:
t = (sample mean - population mean) / (sample standard deviation / sqrt(sample size))
Plugging in the given values:
t = (4.23 - 5.00) / (1.91 / sqrt(46)) = -4.05
We can use a t-distribution table to find the p-value associated with this test statistic. With 45 degrees of freedom (sample size - 1), the p-value for t = -4.05 is extremely low, much less than 0.001, the significance level commonly used in hypothesis testing.

Probability:
Probability defines the probability of an event occurring. There are many real world situations where we need to predict the outcome of an event. We may or may not be certain about the outcome of an event. In such cases, I say that this event may or may not occur. Probability in general has excellent applications for making probability-based predictions in games and economics, and it also has widespread applications in this emerging field of artificial intelligence. The probability of an event can be calculated by simply dividing the number of favorable outcomes by the total number of possible outcomes using the probability formula. The value of the probability that an event will occur can range from 0 to 1. This is because the preferred number of outcomes can never exceed the total number of outcomes. Also, the resulting favorable number can never be negative. The formula for calculating the probability of a
event is:
probability (event) = favorable outcome/total outcome
Now,
According to the Question:

The value of I is -1.
What is the Value of i?This article's introduction included a proposition. The specific measure or value of what I stands for was the subject of the statement. It is discussed in this section of the article along with an explanation of its value.
Iota is the term used to describe the imaginary portion of a complex number. The symbol "iota" or I is used to represent an imaginary number's value. An imaginary number is produced when we square a negative number.
The value of I is -1.
The concept of complex numbers is understood using this value of i.
x2 plus 1 equals zero in a quadratic equation.
x2 = -1
x = √-1
The imaginary portion is shown as -1.
I = √-1
i2 = -1
An imaginary number can be squared to get a negative value, as was previously discussed.
I = √-1
both sides being square
i2 = -1
An imaginary number plus a real number are combined to get any complex number. Iota, sometimes known as I stands for all non-real quantities.
