Answers

The derivative is always negative on (0, infinity), therefore , f is decreasing and thus has an inverse on this interval.

Hope This Helped!!! :)

Final answer:

To show that f(x) = cot(x) is strictly monotonic on the interval (0,pi), we need to show that the derivative of f(x) is either strictly positive or strictly negative on that interval.

Explanation:

To show that f(x) = cot(x) is strictly monotonic on the interval (0,pi), we need to show that the derivative of f(x) is either strictly positive or strictly negative on that interval.

The derivative of f(x) can be found using the chain rule as follows:

Find the derivative of cot(x): d(cot(x))/dx = -csc^2(x)Since f(x) = cot(x), the derivative of f(x) is -csc^2(x).

Now, let's consider the interval (0,pi). The function f(x) = cot(x) is defined on this interval, and its derivative -csc^2(x) is strictly negative for all x in (0,pi). Therefore, f(x) is strictly decreasing on the interval (0,pi), which means it is strictly monotonic.

Since f(x) is strictly monotonic on the interval (0,pi), it has an inverse function on that interval. The inverse function of f(x) is denoted as f^{-1}(x).

in the drawing six out of every 10 tickets are winning tickets of the winning tickets one out of every three awards is a larger prize what is the probability that a ticket is randomly chosen will award a larger prize

Answers

Final answer:

The probability that a randomly chosen ticket will award a larger prize is calculated by multiplying the probability of getting a winning ticket with the probability that the winning ticket is for a larger prize, which results in a 20% chance.

Explanation:

The question is seeking to determine the probability that a ticket chosen at random from a raffle will award a larger prize. We are given that 6 out of every 10 tickets are winning tickets, and of those winning tickets, 1 in every 3 is for a larger prize. To find this probability, we need to multiply the probability of a ticket being a winner by the probability of the winning ticket awarding a larger prize:

Probability of a winning ticket = 6/10 or 0.6Probability of a larger prize if it's a winning ticket = 1/3 or approximately 0.333

Now, we multiply these probabilities:

Probability of a larger prize = Probability of winning ticket × Probability of a larger prize given a winning ticket

Probability of a larger prize = 0.6 × 0.333

Probability of a larger prize = 0.2 or 20%

Answer: B or 1/5

The awnser is ten hope I helped you have to count how many spaces Joan travel to Gary and how many spaces he traveled from garb to kash

The answer is: 22.4339811320566038 mi.
→ Consider rounding to 22.43 mi.
_______________________________________________________
(Note: Do not forget the units, in "miles", which can be abbreviated as: "mi.").
____________________________________________________________________
Explanation:
_____________________________________________________________________
Let us assume that, at the beginning, Joan is leaving her own house to pick up Kash, first.
_____________________________________________________________________
Then, the answer to our problem is the sum of the length of all sides of the triangle given, remember that each "unit" on the graph represents miles.
_____________________________________________________________________
We can solve this using the Pythagorean theorem:
_____________________________________________________________________
a² + b² = c² ; in which: c = the distance from Joan's house to Kash's house;
b = the distance from Kash's house to Gary's house;
a = the distance from Gary's house to Joan's house;
_____________________________________________________________________
Our answer is the sum of: "a + b + c".
_____________________________________________________________________
Using the graph, we can the determine the values for: "a" and "b";
Using the Pythagorean theorem, we can determine the value for "c";
then we can add: "a + b + c" to determine our answer.
_____________________________________________________________________
From inspecting the graph:
_____________________________________________________________________
b = the distance from Kash's house to Gary's house = 8 mi. [miles] ;
a = the distance from Gary's house to Joan's house = 5 mi. [miles] ;
__________________________________________________________
Using the Pythagorean theorem, we want to solve for "c":
__________________________________________________________
a² + b² = c² ; We substitute our known values for "a" and for "b" :
_____________________________________________________
5² + 8² = c² ; Simplify:
_____________________________________________________
25 + 64 = c² ;

89 = c² ; Take the positive square root of both sides to solve for "c";
_______________________________________________________
√89 = √(c²) ; c = √89 = 9.4339811320566038
_______________________________________________________
Now, we can find our answer:
_______________________________________________________________
a + b + c = 5 + 8 + (9.4339811320566038) = 22.4339811320566038 mi.
→ Consider rounding to 22.43 mi. ;
which is our answer.

in a certain class, the ration of passing grades to failing grades is 9 to 3. If 17 grades were failing, how many passing grades were there?

Answers

[tex] \frac{9}{3} = \frac{x}{17} cross multiply 3x=17*9=153 x= \frac{153}{3} =51[/tex]

Final answer:

The ratio of passing to failing grades in the class is 3 to 1. With 17 failing grades, we can determine there were 51 passing grades by setting up a proportion and solving for the number of passing grades.

Explanation:

The question relates to the ratio of passing grades to failing grades and asks us to find the number of passing grades if there are 17 failing grades. The ratio given is 9 to 3, which simplifies to 3 to 1 (since both 9 and 3 are divisible by 3). This means for every 3 passing grades, there is 1 failing grade.

Since there are 17 failing grades and the ratio of failing to passing is 1 to 3, we can set up a proportion to find the number of passing grades (p):

1/3 = 17/p

Multiplying both sides by p and then by 3 gives us:

3 × 17 = 1 × p

51 = p

Therefore, there were 51 passing grades.

Describe how the graph of y=log (10 000x) is related to the graph of y=log x

Answers

Background: log (a . b) = log a + log b
hence log(10000x) = log 10000 + log x but we know that log 10000 = 4
= 4 + log x
therefore the graph of log(10000x) is just the graph of log x transposed by 4

graph of y=log (10 000x) is related to the graph of y=log x is transposed by 4 units.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given graphs of y=log (10 000x)

y equal to ten thousand of x

We know a property of log.

logab=loga+logb

Log ab equal to log a plus log b.

So log (10 000x) =log 10000+log x

=4+logx

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.

So the graph of log (10 000x) is transposed by 4 units.

Hence graph of y=log (10 000x) is related to the graph of y=log x is transposed by 4 units.

Anastasia uses the equation p = 0.7(rh + b) to estimate the amount of take-home pay, p, for h hours worked at a rate of r dollars per hour and any bonus received, b.

What is an equivalent equation solved for h?

h = (– b)÷ r
h = – b ÷ r
h = ÷ r – b
h = ÷ r

Answers

Answer:

Step-by-step explanation:

Final answer:

The equivalent equation solved for h is h = -b/r. To derive this equation, we can isolate h in the given equation p = 0.7(rh + b) by multiplying both sides by the reciprocal of 0.7, distributing, and simplifying, option n 2 is correct.

Explanation:

The equivalent equation solved for h is h = −b ÷ r.

To derive this equation, we need to isolate h in the given equation p = 0.7(rh + b). We can start by multiplying both sides of the equation by the reciprocal of 0.7, which is 1.4286 (approximately).

Then, we can distribute the 1.4286 to the terms inside the parentheses to get p = 1.4286rh + 1.4286b. Next, we can subtract 1.4286b from both sides of the equation to isolate the 1.4286rh term.

Finally, we can divide both sides of the equation by 1.4286r to solve for h, which gives us the equivalent equation h = −b ÷ r.

After 1 minute of competition, Joey has eaten 10 hot dogs. Joey wants to know the number of hot dogs per minute that he needs to eat for the next 9 minutes to break his own record.

Answers

Final answer:

Joey Chestnut needs to eat more than 6.89 hot dogs per minute for the next 9 minutes to break his record of 72 hot dogs.

Explanation:

To find the number of hot dogs per minute Joey Chestnut needs to eat in the remaining 9 minutes to break his record, we need to start by calculating how many more hot dogs he needs to surpass 72 hot dogs. Since he has already eaten 10 hot dogs in the first minute, he needs to eat more than 62 hot dogs in the next 9 minutes to break the record.

We calculate the average number of hot dogs per minute by dividing the remaining number of hot dogs by the number of minutes left. So,

Number of hot dogs needed > 72 hot dogs - 10 hot dogs = 62 hot dogsMinutes remaining = 9 minutesHot dogs per minute needed = Number of hot dogs needed / Minutes remainingHot dogs per minute needed > 62 hot dogs / 9 minutes ≈ 6.89 hot dogs per minute

If x > 1, then which of the following has the LEAST value?

Answers

Final answer:

If x > 1, then the expression (0.25 - x) will have the least value when x is equal to 1.

Explanation:

If x > 1, then the expression (0.25 - x) will be negative. When comparing negative values, the one with the least absolute value will have the least value. Therefore, to find the expression with the least value, we want to find the largest negative value for (0.25 - x). Since x > 1, the largest negative value for (0.25 - x) would occur when x is closest to its minimum value, which is 1. Therefore, the expression (0.25 - x) will have the least value when x is equal to 1.

Hmmmm, the correct answer isn't stated here. The answer should be: [tex]B=-A+ \frac{R}{x} [/tex]

The answer is C. Solve it like you would a equation with b for the variable. You first, distribute the x into the problem in the parenthesis: R=Ax+Bx. Then, you realize that Ax is positive and the to remove it is to subtract Ax and will leave with Bx on the right side of this equation (remember, what you do on one side, you must do to the other in order to keep it balanced). That means you must subtract Ax from the left side of the equation also, leaving you with: R-Ax=Bx. Now, to get that B alone, you must realize that the right hand side of the equation is a multiplication problem so the only way to remove it is to divide right? So the right hand side now is only B. REMEMBER! You must do to both sides of the equation so you must divide the left hand side of the equation by X. And you are left with R - Ax/ X. Same as (R-Ax)/x. So choice c is the correct answer.
