Answer:

Step-by-step explanation:
let f: R→[1,+[infinity]) by f(x)=x
2
+1. This is a surjective but not injective function. So, it has right inverse. but it is nat unique. Provide twas dhfferent. right inverse functians of f.
The two right inverse functions of f are g(x)=x−1 and h(x)=−x−1. Both functions map from [1,∞) to R, and they both satisfy f(g(x))=f(h(x))=x for all x∈[1,∞).
A right inverse function of f is a function g such that f(g(x))=x for all x in the domain of f. In this case, the domain of f is R, and the range of f is [1,∞).
We can see that g(x)=x−1 is a right inverse function of f because f(g(x))=f(x−1)=x−1+1=x for all x∈[1,∞). Similarly, h(x)=−x−1 is also a right inverse function of f because f(h(x))=f(−x−1)=x−1+1=x for all x∈[1,∞).
The fact that f has two different right inverse functions shows that it is not injective. An injective function has a unique right inverse function. However, a surjective function always has at least one right inverse function.

Shonna skateboarded for some number of minutes on Monday. On Tuesday, she skateboarded for twice as many minutes as she did on Monday, and on Wednesday, she skateboarded for half the sum of minutes from Monday and Tuesday. Altogether, she skateboarded for a total of three hours. How many minutes did she skateboard each day?
Call the minutes she spend skateboarding on Monday as x
On Tuesday, she skateboarded for twice as many minutes -> 2x
On wednesday, she skateboarded for half the sum of minutes from Monday and Tuesday -> (x+2x)/2 = 1.5x
In total, she skateboarded a total of 3 hours (180 minutes) -> 2x + x + 1.5x = 4.5x = 180
-> x = 180 : 4.5 = 40
So, she spend 40 minutes on Monday, 80 minutes on Tuesday and 60 minutes on Wednesday
Recheck : She spend 80 : 40 = 2 times as much time on Tuesday than Monday, and she spend half the sum of Monday and Tuesday : (40+80)/2 = 60, and 40 + 80 + 60 adds up to 180, which is 3 hours.
Amongst the 25 parts on the wheel:
12 parts give you x2 and are labelled "1" (yellow)
6 parts give you x3 and are labelled "3" (green)
4 parts give you x5 and are labelled "5" (blue)
2 parts give you x10 and are labelled "10" (pink)
1 part gives you x20 and is labelled "20" (red)
How to play the game:
Your objective is obviously to make a profit, you get a currency called scrap, say I start with 100 scrap. You can bet any amount (within the initial 100 scrap) on any one of those numbers/parts on the wheel.
If I bet 50 scrap on the red 20 and spun the wheel and it landed on 20, I would get 50 x 20 = 1000 scrap.
However you can bet on more than one colour on the wheel at one time, meaning I can bet 50 scrap on 3 (green), 30 scrap on 5 (blue) and 20 scrap on 10 (pink)... if the wheel were to then land on 1 (yellow) or 20 (red) I would lose all my scrap, if it were to land on 5 (blue) then I would lose my 50 scrap on 3 (green) and my 20 scrap on 10 (pink), BUT because it landed on 5 (blue) then I would get 5 x 30 scrap which is 150.
Probabilities:
The wheel has an equal chance to land on any of the 25 parts of the wheel meaning because their is only one 20 (red) on the wheel, you have a 1 in 25 chance of landing on it. The probability and percentages are as follows:
1 (yellow): 12/25 or 48%
3 (green): 6/25 or 24%
5 (blue): 4/25 or 16%
10 (pink) 2/25 or 8%
29 (red) 1/25 or 4%
Task:
My task for you is to streamline my betting odds allowing me to either make guaranteed profit from my initial 100 scrap or a strategy that gives me the best possible odds to make profit.
To streamline your betting odds and increase your chances of making a profit from your initial 100 scrap, you can use a combination of different betting strategies.
Here are a few possible strategies:
1) Spread your bets: Instead of betting all of your scrap on one number, you can spread your bets across multiple numbers to increase your chances of winning.
For example, you could bet 25 scrap on 1 (yellow), 25 scrap on 3 (green), 25 scrap on 5 (blue), and 25 scrap on 10 (pink). This way, you have a 48% chance of winning on 1 (yellow), a 24% chance of winning on 3 (green), a 16% chance of winning on 5 (blue), and an 8% chance of winning on 10 (pink).
2) Bet on the most likely outcomes: Another strategy is to bet on the numbers with the highest probabilities of winning. For example, you could bet 50 scrap on 1 (yellow) and 50 scrap on 3 (green), which have the highest probabilities of winning at 48% and 24%, respectively.
3) Use a combination of the above strategies: You could also combine the above strategies to increase your chances of winning. For example, you could bet 25 scrap on 1 (yellow), 25 scrap on 3 (green), 25 scrap on 5 (blue), and 25 scrap on 10 (pink), and then also bet an additional 50 scrap on 1 (yellow) and 50 scrap on 3 (green).
Overall, the key to streamlining your betting odds is to spread your bets across multiple numbers and focus on the numbers with the highest probabilities of winning. By using a combination of different betting strategies, you can increase your chances of making a profit from your initial 100 scrap.

Find the slope and the y-intercept of the equation below:
1. 4x-3y=12
2. 2y=6x-12
if you can put the step please do so. Tysm.
Answer + Explanation:
1. you want to rearrange the equation ( don't change the actual value ) to put it in the form y = mx + b. in this form, m represents the slope and b represents the y-intercept.
this is how you would do that:
4x - 3y = 12
subtract 4x from both sides
-3y = -4x + 12
divide both sides by -3
y = 4/3x - 4
this means the slope is 4/3 and the y-intercept is -4
2. do the same thing, rearranging into y = mx + b form
2y = 6x - 12
divide both sides by 2
y = 3x - 6
this means the slope is 3 and the y-intercept is -6
Deceleration, A car slows down with an acceleration of a(t) = -15 ft/s^2. Assume that v(0)=60 ft/s, s(0) =0, and t is measured in seconds. A) Determine and graph the position function for t> 0. B) How far does the car travel in the time it takes to come to a rest?
The car travels a Distance of 120 ft in the time it takes to come to a rest.
A) Determine and graph the position function for t > 0
Given that: Deceleration of car, a(t) = -15 ft/s²Velocity of car, v(0) = 60 ft/sInitial position of car, s(0) = 0
We know that:v(t) = v(0) + a(t) * tHere, v(0) = 60 ft/sa(t) = -15 ft/s²v(t) = 60 - 15tThen, s(t) = s(0) + v(0)t + (1/2)a(t)t²Putting in the values, we get:s(t) = 60t - 7.5t²
Thus, the position function for t > 0 is s(t) = 60t - 7.5t²
.Graph: We can use the above formula for position function to create a graph using a graphing calculator. The graph will look like this:
B) How far does the car travel in the time it takes to come to a rest?When the car comes to rest, its final velocity (v) will be 0. We can find the time taken to come to rest as follows:0 = 60 - 15t15t = 60t = 60/15 = 4 seconds
The car travels for 4 seconds before coming to rest.
We can find the distance travelled during this time as follows:Distance travelled, s = s(4) = 60(4) - 7.5(4²) = 240 - 120 = 120 ft
Therefore, the car travels a distance of 120 ft in the time it takes to come to a rest.

Holly Krech is planning for her retirement, so she is setting up a payout annuity with her bank. She wishes to receive a payout of $1,800 per month for twenty years. She must deposit $218,437.048 and the total amount that Holly will receive from her payout annuity will be $432,000.
A. How large a monthly payment must Holly Krech make if she saves for her payout annuity with an ordinary annuity, which she sets up thirty years before her retirement?
B. how large a monthly payment must she make if she sets the ordinary annuity up twenty years before her retirement?
A. To save for her payout annuity with an ordinary annuity set up thirty years before her retirement, Holly Krech must make a monthly payment of $175.97.
B. If she sets up the ordinary annuity twenty years before her retirement, Holly Krech must make a monthly payment of $432.00.
What is the monthly payment required for an ordinary annuity set up 30 years before retirement?To calculate the monthly payment for an ordinary annuity set up thirty years before retirement, we can use the formula for the present value of an ordinary annuity. Given the deposit amount of $218,437.048 and the total amount received from the annuity of $432,000, and solving for the monthly payment, we find that Holly must make a monthly payment of $175.97.
How much must be paid monthly for an ordinary annuity set up 20 years before retirement?For an ordinary annuity set up twenty years before retirement, we use the same formula for present value. With the deposit amount and total amount received unchanged, we solve for the monthly payment, which comes out to be $432.00.
It's important to note that the monthly payment increases when the annuity is set up closer to the retirement date. This is due to the shorter time period available for saving, resulting in a higher required contribution to reach the desired payout amount.

Consider the following function. f(x) = ex x8 (a) find the intervals of increase or decrease. (enter your answers using interval notation.)
The interval of increase for the function f(x) = ex x8 is (0, ∞).
To determine the intervals of increase or decrease for the given function, we need to analyze the sign of the derivative.
Let's find the derivative of f(x) with respect to x:
f'(x) = (ex x8)' = ex x8 (8x7 + ex)
To determine the intervals of increase, we need to find where the derivative is positive (greater than zero).
Setting f'(x) > 0, we have:
ex x8 (8x7 + ex) > 0
The exponential term ex is always positive, so we can ignore it for determining the sign. Therefore, we have:
8x7 + ex > 0
Now, we solve for x:
8x7 > 0
Since 8 is positive, we can divide both sides by 8 without changing the inequality:
x7 > 0
The inequality x7 > 0 holds true for all positive values of x. Therefore, the interval of increase for the function is (0, ∞), which means the function increases for all positive values of x.
The function f(x) = ex x8 increases in the interval (0, ∞).

The exponential function is y = 1200(1.04)^t and the investment amount after 16 years is $2247.58.
What is exponential function?
The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.
Jayden invests $1,200 in a savings account. Each year, the value increases by 4%.
Let t = time in years
Let y = amount of money invested in savings account
Start with $1200 and each year add 4% interest to the amount in the bank.
1st year: Interest = 1200 × (0.04) = $48
This is added to the previous amount -
= $1200 + $1200 × (0.04)
= $1200 (1+0.04)
= $1200 (1.04)
= $1248
2nd year: Previous amount + interest on the previous amount
= $1248 (1+0.06)
= $1248 (1.06)
= $1297.92
So, the exponential formula becomes -
y = 1200(1.04)^t
Now, to find the value of investment after 16 years, substitute t = 16.
y = 1200(1.04)^t
y = 1200(1.04)^16
y = 1200(1.87298125)
y =$2247.58
Therefore, the value of investment after 16 years is $2247.58.
