Which of the following values for X will make relation A shown below, a function?
A=(5,3),(4,9),(7,2),(x,6)
3
4 (I know 4 is wrong)
5
7
The value of x that makes the relation a function is 3.
Option A is the correct answer.
We have,
A = (5, 3), (4, 9), (7, 2), (x, 6)
Given the points (5, 3), (4, 9), (7, 2), and (x, 6), we need to ensure that x does not repeat in the relation.
If we substitute the given values of x (3, 4, 5, 7) into the relation, we find:
For x = 3: (3, 6)
For x = 4: (4, 6)
For x = 5: (5, 6)
For x = 7: (7, 6)
Now,
A function can not have the same output for the same input.
So,
(4, 6) and (4, 9) are not possible.
(5, 6) and (5, 3) are not possible.
(7, 6) and (7, 2) are not possible.
And,
(3, 6) is possible
Thus,
The value of x that makes a function is 3.

Step-by-step explanation:
A hacker is trying to guess someone's password. The hacker knows (somehow) that the password is 9 characters long, and that each character is either a lowercase letter, (a, b, c, etc.), an uppercase letter (A, B, C, etc.) or a numerical digit (0, 1, 2, 3, 4, 5, 6, 7, 8, or 9). Assume that the hacker makes random guesses. What is the probability that the hacker guesses the password on his first try? Enter your answer as a decimal or a fraction, not a percentage.
The probability that the hacker guesses the password on their first try is extremely low.
What is the probability that the hacker guesses the password on his first try?
There are 26 lowercase letters, 26 uppercase letters, and 10 numerical digits, for a total of 62 possible characters for each position in the password. Since the password is 9 characters long, there are \(62^{9}\) possible passwords.
The probability that the hacker guesses the password on their first try is 1 out of the total number of possible passwords:
Probability = 1 / (\(62^{9}\))
Using a calculator, this can be simplified to approximately 1.2 x \(10^{-16}\)
Therefore, the probability that the hacker guesses the password on their first try is extremely low.

is the binomial probability mass function formula related to the compound interest formula?
binomial has : (1 - p)^(n - k)
compound interest has : (1+r)^(nt)
For binomial probability mass function formula and compound interest formula, These both involve the use of exponents, they are not otherwise related to each other in any significant way.
What is Compound interest?
Compound interest is the interest that is earned not only on the initial principal amount of an investment, but also on any interest that has accumulated over time. In other words, it is interest that is "compounded" or added to the principal amount at specific intervals, such as daily, monthly, quarterly, or annually.
Now,
The binomial probability mass function formula and the compound interest formula are not directly related to each other, as they are used to model different types of phenomena.
The binomial probability mass function is used to calculate the probability of obtaining a certain number of successes in a fixed number of independent trials, where each trial has two possible outcomes (success or failure) and the probability is same. The binomial probability mass function is
P(x) = pˣ (1-p)ⁿ⁻ˣ
where X is the number of successes, k is the specific number of successes we are interested in, n is the total number of trials, p is the probability of success on each trial, and represents the binomial coefficient.
The compound interest formula, on the other hand, is used to calculate the value of an investment over time, assuming a fixed interest rate and compounding periods. The future value is
FV = PV x (1 + r/n)ⁿˣ
where FV is the future value of the investment, PV is the present value of the investment, r is the interest rate (expressed as a decimal), n = number of times interest is compounded per year, and x = number of years.
While both formulas involve the use of exponents, they are not otherwise related to each other in any significant way.

The binomial probability mass function formula and the compound interest formula are not directly related to each other.
The binomial probability mass function formula is used to calculate the probability of observing a certain number of successes in a fixed number of independent trials, where each trial has only two possible outcomes (success or failure) and the probability of success is constant across all trials. The formula is:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where X is the random variable representing the number of successes, k is the number of successes we want to observe, n is the total number of trials, p is the probability of success, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.
On the other hand, the compound interest formula is used to calculate the value of an investment that earns a fixed interest rate over a certain period of time, assuming that the interest is compounded at regular intervals. The formula is:
A = P * (1 + r/n)^(nt)
where A is the final amount of the investment, P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, t is the number of years, and (1 + r/n)^(nt) represents the growth factor of the investment.
While both formulas involve exponents and use the terms (1 - p) and (1 + r/n), they are fundamentally different in their purpose and application.

an angle is 10 degrees more than 3 times the measure of its compliment. find the measure of both angles
Answer:
20° and 70°
Step-by-step explanation:
complimentary angle sum to 90°
let x be the compliment then the angle is 3x + 10 , so
x + 3x + 10 = 90 , that is
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
3x + 10 = 3(20) + 10 = 60 + 10 = 70
the 2 angle measures are 20° and 70°

P(x) 2x^4 - 4x^3 - 16x^2
9514 1404 393
Answer:
P(x) = (2x)(x)(x-4)(x+2)
Step-by-step explanation:
Once the common factor of 2x^2 is factored out, you have ...
P(x) = 2x^2(x^2 -2x -8)
To factor the quadratic, you look for factors of -8 that have a sum of -2.
-8 = (1)(-8) = 2(-4)
These last factors have that sum, so we can write P(x) as ...
P(x) = (2x)(x)(x +2)(x -4)

Find the amount (future value) of the ordinary annuity. (Round your answer to the nearest cent.)
$300/week for 9 1/2
years at 5.5%/year compounded weekly
Answer: $227,226.51
Step-by-step explanation:
First, we need to convert the period to weeks.
9 1/2 years = 9.5 years
1 year = 52 weeks
9.5 years = 494 weeks
Next, we can use the formula for the future value of an annuity:
FV = (PMT x (((1 + r/n)^(n*t)) - 1)) / (r/n)
where:
PMT = payment amount per period
r = annual interest rate
n = number of compounding periods per year
t = number of years
Plugging in the given values:
PMT = $300
r = 0.055 (5.5% expressed as a decimal)
n = 52 (compounded weekly)
t = 9.5 years = 494 weeks
FV = ($300 x (((1 + 0.055/52)^(52*494)) - 1)) / (0.055/52)
FV = $227,226.51
Therefore, the future value of the annuity is approximately $227,226.51.

The missing variables for item 1 in this problem are given as follows:
c = 2.r = 4.What are the trigonometric ratios?The three trigonometric ratios are the sine, the cosine and the tangent of an angle, and they are obtained according to the formulas presented as follows:
Sine = length of opposite side to the angle/length of hypotenuse of the triangle.Cosine = length of adjacent side to the angle/length of hypotenuse of the triangle.Tangent = length of opposite side to the angle/length of adjacent side to the angle = sine/cosine.For the angle of 60º, we have that:
\(2\sqrt{3}\) is the opposite side.c is the adjacent side.Hence the length c is obtained as follows:
tan(60º) = \(\frac{2\sqrt{3}}{c}\)
\(\sqrt{3}c = 2\sqrt{3}\)
c = 2.
Applying the Pythagorean Theorem, the length r is given as follows:
r² = \(2^2 + (2\sqrt{3})^2\)
r² = 16
r = 4.

#SPJ1
Answer:
c = 2
r = 4
Step-by-step explanation:
From observation of the given right triangle, we can see that its interior angles measure 30°, 60° and 90°. Therefore, it is a special 30-60-90 triangle.
The side lengths in a 30-60-90 triangle have a special relationship which can be represented by the ratio 1 : √3 : 2, where:
The shortest leg is opposite the 30° angle.The longest leg is √3 times the length of the shortest leg and is opposite the 60° angle.The hypotenuse is the longest side and twice the length of the shortest leg.Therefore, the formula for the side lengths is a : a√3 : 2a, where "a" represents a scaling factor that can be any positive real number.
Side a is opposite the 30° angle (shortest leg).Side a√3 is opposite the 60° angle (longest leg).Side 2a is the hypotenuse (longest side).Therefore, if we know the length of one side of a 30-60-90 triangle, we can calculate the length of the other sides using this ratio.
In triangle #1, the longest leg is 2√3.
As a√3 is the longest leg, we can use this to calculate the scale factor "a".
\(\begin{aligned}a\sqrt{3}&=2\sqrt{3}\\\\\dfrac{a\sqrt{3}}{\sqrt{3}}&=\dfrac{2\sqrt{3}}{\sqrt{3}}\\\\a&=2\end{aligned}\)
Therefore, the scale factor "a" is 2.
The side labelled "c" is the shortest leg opposite the 30° angle. Therefore:
\(c = a=2\)
The side labelled "r" is the hypotenuse of the triangle. Therefore:
\(r = 2a = 2 \cdot 2=4\)
Therefore:

Total water bill for the month is $62.37.
It seems that you may have accidentally left out the total amount of your water bill.
The total amount by simply adding the amounts of the individual bills together:
Total water bill =\($36.34 + $26.03\)
= \($62.37\)
You have not provided enough information to determine your total water bill.
You have only given the amounts of your individual bills from Metro Water Services and Madison Suburban Utility District.
To find your total water bill, you simply need to add the two bills together.
So, the total amount you owe for water this month would be:
Total water bill = \($36.34 + $26.03\)
= \($62.37\)
It appears that you may have forgotten to include the full amount of your water bill by accident.
Simple addition of the separate bill amounts yields the following sum:
Water bill total = \($36.34 + $26.03\)
= \($62.37\)
Your total water bill cannot be calculated because not enough information has been given.
Only the amounts of your individual Metro Water Services and Madison Suburban Utility District bills have been provided.
You just need to combine the two invoices together to get your total water bill.
As a result, this month's total water bill for you would be:
Water bill total = \($36.34 + $26.03\)
