A limit in mathematics is a value that a function approaches when the input gets closer to a certain value. Limits are used to find a function's derivative and integral as well as to characterize how a function behaves around particular places.

lim x -> c f(x) = L

(a) False.

According to the rules of limits, if both limits are present, the limit of a sum of two functions is equal to the total of their limits. The assertion, however, cannot be valid if one or both of the boundaries do not exist.

(b) False.

According to the limit laws, if the sum of two functions approaches 0, then the sum of their limits also does. The opposite of this statement is untrue, though.

In this instance, even if x approaches 5 and both f(x) and g(x) approach 0, the product of their limits, f(x)g(x), may not exist at all or may approach a non-zero value.

(c) False.

A function's limit as x gets closer to a number from the right is not always the same as the limit as x gets closer to the same number from the left.

Although f(3) = 2 in this instance and lim x3+ f(x) = 2, the limit of f(x) as x approaches 3 from the left may not be 2.

(d) False.

The absence of a limit does not imply the existence of the function's value at that time.

In this instance, the value of h(0) may still exist even though the limit of h(t) as t approaches 0 does not exist.

The solution is Option C.

The measure of sides of 7 , 9 , 17 does not form a triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ABC

Now , the measure of sides of the triangle are a , b , c

The value of a = 7

The value of b = 9

The value of c = 17

Now , The sum of the two smallest numbers has to equal a number greater that the largest one

So , 7 + 9 = 16

And , 16 is not greater than 17

Hence , the triangle cannot be formed with sides 7 , 9 , 17

Use the distributive property and multiply everything inside the parenthesis by 4.

The value of x in the equation (x + 7)² - 11 = 0 are x = -7 + √11 and x = -7 - √11

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

The variable to be solved is x . Variables are numbers represented by letters in an equation.]

Therefore,

(x + 7)² - 11 = 0

(x + 7)(x + 7) - 11 = 0

x² + 7x + 7x + 49 - 11 = 0

x² + 14x + 38 = 0

Therefore, let's factorise the quadratic equation as follows:

x² + 14x + 38 = 0

Using the quadratic formula,

[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

Answer:

x = 22.5

<ADE = 67.5

Step-by-step explanation:

Triangle = 180 degrees

180 - 1 right angle (90 degrees) = 90 degrees

90 = 4x

x = 22.5

<ADE is corresponding to <ABC, therefore <ADE is also equal to 3x. Since we know x = 22.5 already:

3 x 22.5 = 67.5

so <ADE = 67.5

To find out how much candy Vanessa should eat each day, we first need to find the total amount of candy in the box. If the box weighs 1/8 of a pound, we can convert this weight to ounces to get a clearer idea of the quantity of candy. There are 16 ounces in a pound, so 1/8 of a pound is equal to 1/8 * 16 = 2 ounces.

Now that we know the total amount of candy, we can divide this by the number of days that Vanessa wants the candy to last to find out how much she should eat each day. If the candy is meant to last 2 days, she should eat 2 ounces / 2 days = 1 ounce of candy per day.

Given that, at least 53 people buy food from the food truck. It means minimum 53 people buy the food, and number greater than 53 is quite possible; however, the possibility of people buying food less than 53 is not possible.

Since the number of people is alway 53 or greater than 53 therefore we may represent this condition using the greater and equal sign.

Lets use the variable p for people who buy the food.

Now the inequality can be written as

Probability is the part of mathematics that discusses the size of the likelihood of something happening in life. Indeed, there are many events that cannot be ascertained to occur or not occur at a later time. but by knowing the measure of the success or failure of the expected event to occur, people can make better and wiser decisions about what should be done. Probability theory provides methods related to uncertainty and is an integral part of the decision-making process.

The concepts of probability are the basis of samples and the inferences about the population that can be made from a sample. After understanding the concept of probability which is the basis of statistics, we will then be given the theory of random variables and their properties, formation of probability distributions, socialization of various discrete and constant random variable probability distributions, and statistical sampling distributions.

The difference between the amount he planned to spend and what he actually spent was negative and greater than 20 dollars, indicating that he overspent by more than 20 dollars.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Tanisha is a waitress at a restaurant.

From past experience, Tanisha noticed that she will get about $14 in tips for each table she waits on.

The amount of money earned by Tanisha in 10 days will be:-

The equation for the total cost, y, in terms of the number of kites purchased, x, is y = 4x + 8.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that, there is a charge of $4 per kite plus a flat rate of $8 to ship these items to Alaska.

Let x be the number of kites purchased.

Cost for the kites purchased = 4x

Total cost including the shipping charge = 4x + 8

When x = 0, y = $8

When x = 1, y = 4 + 8 = 12

When x = 4, y = 16 + 8 = 24

When x = 7, y = 28 + 8 = 36

When x = 10, y = 40 + 8 = 48

The tertiary alkene (c) is the most stable, followed by the secondary alkene (a), and finally the primary alkene (b).

The stability of alkenes depends on the number of alkyl substituents attached to the double bond, as well as their positions. Alkenes with the most stable arrangement have the greatest number of alkyl substituents attached to the double bond and are known as tertiary alkenes. Secondary alkenes have two alkyl substituents attached to the double bond and primary alkenes have only one alkyl substituent attached to the double bond.

Based on this information, the order of decreasing stability of alkenes is:

C. Nonsampling error is the error that results from factors outside of the sampling process, such as undercoverage, nonresponse bias, response bias, or data entry errors. Sampling error is the error that results because a sample is being used to estimate information about a population.

Nonsampling error describes problems in data collecting and processing that take place unrelated to the sampling procedure itself. It is brought on by things like inaccurate data collection or measurement, interviewer bias, response bias, undercoverage, or data entry mistakes. Whether a sample or a whole census is employed, nonsampling mistakes can still happen.

On the other hand, sampling error is the error that happens when a sample is used to estimate the characteristics of a population. There will always be some degree of uncertainty when drawing conclusions about the population from sample data because the sample is only a part of the whole population. Sampling error develops as a result of the random variation present during the selection of a sample.

                                                                                        = 12! / [(12 - 4)! × 4!]

                                                                                            = 12! / [(8! × 4!)]

                                                                                            = 495

No. of ways to select 4 people from the remaining 8 for the second group = ⁸C₄   = 8! / [(8 - 4)! × 4!] = 8! / [(4! × 4!)] = 70

No. of ways to select 4 people from 4 for the third group = ⁴C₄  = 4! / [(4 - 4)!] × 4!] = 4! / [(0! ×4!)] = 1

Total no. of ways to select people for group = (495 x 70 x 1) / 3! = 34650 /6 = 5775

Hence, we can split 12 people into 3 teams of 4 in 5775 different ways.
