At what value of x does the graph of the function f(x) have a vertical asymptote?
F(x) = 5X/ 2X-6
Solve :
3x − 6 = 2x − 1
Which function is shown in the graph below?
Answer: The correct option is 2.
Explanation:
From the given figure it is easily noticed that the graph intersect the y-axis at y=9 , therefore the y-intercept is (0,9).
To find the equation of the curve put x=0 in each option, If we get y=9 then that option is true.
Option 1:
[tex]y=(\frac{1}{2})^{(x+3)}-1[/tex]
[tex]y=(\frac{1}{2})^{(0+3)}-1=\frac{1}{8}-1=\frac{-7}{8}[/tex]
Option 2:
[tex]y=(\frac{1}{2})^{(x-3)}+1[/tex]
[tex]y=(\frac{1}{2})^{(0-3)}+1=8+1=9[/tex]
Option 3:
[tex]y=(\frac{1}{2})^{(x-1)}+3[/tex]
[tex]y=(\frac{1}{2})^{(0-1)}+3=2+3=5[/tex]
Option 4:
[tex]y=(\frac{1}{2})^{(x+1)}-3[/tex]
[tex]y=(\frac{1}{2})^{(0+1)}-3=\frac{1}{2}-3=\frac{-5}{2}[/tex]
Only the equation in option 2 have the y-intercept (0,9), therefore the correct answer is option second.

How do we refer to self-contained state actions: monadic. dyadic. triadic. k-adic?
In mathematics, self-contained state actions are known as k-adic. Monadic, dyadic, and triadic are specific cases of k-adic functions.
Explanation:In mathematics, self-contained state actions are known as k-adic. The term 'k-adic' refers to functions that take k inputs and produce a single output. Monadic, dyadic, and triadic are specific cases of k-adic functions, where k is 1, 2, and 3, respectively. Thus, it typically refers to a numeral or number system that is based on the value of k, which can be any positive integer.
In such systems, numbers are represented using a base of k, and each digit holds its own place value. K-adic expansions are useful in number theory and algebraic number theory, providing insights into number properties and relationships in various mathematical contexts.

What is the probability that it will NOT be white? Write your answer as a decimal.
13 + 15 + 18 +14 = 60 total hats
15 are white
60-15 = 45 hats that are not white
45/60 reduces to 3/4
3/4 =0.75 probability the hat will not be white

Andrea and raleigh are each rolling a fair, six-sided die. they roll their dice simultaneously, individually keeping a sum until someone reaches 100; whoever reaches 100 first wins. (if they reach 100 on the same roll, it's a tie.) andrea's die has sides 1, 2, 3, 4, 5, and 6. raleigh's has sides 1, 1, 1, 6, 6, and 6. who is more likely to win?
Let An be the likely number of rolls for Andrea to arrive at 100 or more, given that she is n away from the target of 100 (which means her current total is 100 - n ). Then we get the recurrence relation
An = 1 + (1/6) (An-1 + An-2 + An-3 + An-4 + An-5 + An – 6)
and the initial conditions A0 = A-1 = A-2 = A-3 = A-4 = A-5 = 0. This results in A100 = 29.0476 as the amount of expected rolls that Andrea has to make.
Now let Rn to be expected amount of rolls for Raleigh to arrive at 100 or more, given than he is also n away from the target of 100. Now the recurrence relation is:
Rn = 1 + (1/2) (Rn-1 + Rn-6)
with the initial conditions R0 = R-1 = R-2 = R-3 = R-4 = R-5 = 0. This gives us R100 = 29.1837 as the expected amount of rolls for Raleigh.
Therefore Andrea has to make less number of rolls thus she is expected to win.
Winner: Andrea

The area of an artist's square canvas can hold 113 square inches of paint. What is the approximate length of one side of the canvas? (Approximate to the nearest hundredth inch.)
10.62 inches
10.63 inches
10.64 inches
10.65 inches
The area of the square canvas is the square of its side length
The length of the side of the square canvas is 10.63 inches
The area the square canvas can hold is given as:
[tex]Area=113in^2[/tex]
The canvas has a square as its shape, and the area of a square is:
[tex]Area = L^2[/tex]
Where:
L represents the length of the shape (i.e. the square canvas)
So, we have:
[tex]L^2 = 113[/tex]
Take square roots of both sides
[tex]L = \sqrt{113[/tex]
Take the square root of 113
[tex]L = 10.63[/tex]
Hence, the length of the side is 10.63 inches

a randomly generated list of numbers from 0 to 4 is being used to simulate an event with numbers 3 and 4 representing a success. what is the estimated probability of a success
A. 75%
B. 60%
C. 25%
D. 40%
Answer: 40% appex
Step-by-step explanation:
The probability of success, where success is defined as generating a 3 or 4 in a random list of numbers from 0 to 4, is 40%.
To calculate the probability of success in a random number generation scenario. The numbers 0 to 4 are possible outcomes, with 3 and 4 being defined as success. There are 5 equally likely outcomes in total, and 2 of these (3 and 4) represent success. Hence, the probability of success (P(success)) is calculated as the number of successful outcomes divided by the total number of possible outcomes.
P(success) = Number of successful outcomes / Total number of outcomes
P(success) = 2/5
This fraction simplifies equals 0.4, which, when converted into a percentage, results in a 40% chance of success. Therefore, the correct answer is D. 40%.
A mother has 3 kids. Kid A is half the mother's current age. Kid B is 4 years younger than Kid A. In 3 years, Kid C will be 1/5 of his mother's age (not her current age). The sum of all their current ages is the mother's current age.
How old is the mother currently?
How old is each of her kids?
Final answer:
The mother is currently 40 years old. Kid A is 20 years old, Kid B is 16 years old, and Kid C is 36 years old.
Explanation:
Let's denote the mother's current age as M. Kid A's age is A = M/2. Kid B is 4 years younger than Kid A, so B = A - 4 = M/2 - 4. Kid C will be 1/5 of his mother's age in 3 years, so if we denote Kid C's current age as C, we have C + 3 = 1/5(M + 3). The sum of all their current ages is the mother's current age, so M = A + B + C. With these equations, we can solve for M, A, B, and C.
We substitute A and B into the mother's age equation: M = M/2 + M/2 - 4 + C. Rearranging terms, we get M - 4 = C. Now we have two expressions for C: M - 4 and 1/5(M + 3) - 3. Setting them equal to each other, we get M - 4 = 1/5(M + 3) - 3. Solving for M, we find that M = 40 years old.
Now we can find Kid A, B, and C's ages using the mother's age. Kid A is half the mother's age, A = M/2 = 20 years old. Kid B is 4 years younger than Kid A, B = A - 4 = 16 years old. Kid C's age can be found by the substitution, C = M - 4 = 36 years old. So the mother is 40 years old, Kid A is 20 years old, Kid B is 16 years old, and Kid C is 36 years old.
