For the inverse variation function y = k/x (where x, k > 0), what happens to the value of y as the value of x increases? a. Increases c. Increases then decreases b. Decreases d. Decreases then increases.
If the value of x increases then the value of y decreases. Then the correct option is B.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
For the inverse variation function
[tex]\rm y = \dfrac{k}{x}[/tex] (where x, k > 0),
We know that the y is inversely proportional to the x.
Thus, if the value of x increases then the value of y decreases.
Therefore, the correct option is B.

Which of the following shows the extraneous solution to the logarithmic equation? log subscript 4 baseline (x) log subscript 4 baseline (x minus 3) = log subscript 4 baseline (negative 7 x 21) x = negative 7 x = negative 3 x = 3 and x = negative 7 x = 7 and x = negative 3
The extraneous solution is the value of the independent variable for which the problem has no solution. x=3 is an extraneous solution.
What is an extraneous solution?
An extraneous solution is a solution that develops from the process of addressing the problem but is not a real solution to the problem, such as an equation.
In order to know the extraneous solution, we need to find the value of x in the given equation,
[tex]\rm log_4(x)+log_4(x-3)= log_4(-7x+21)[/tex]
Using the logarithmic property,
[tex]\rm log_4[x(x-3)]= log_4(-7x+21)[/tex]
Taking the anti-log, we will get,
[tex]x(x-3)= -7x+21\\\\x^2-3x=-7x+21\\\\x^2+7x-3x-21=0\\\\x(x+7)-3(x+7)=0\\\\(x-3)(x+7)=0[/tex]
If we substitute the factors with the 0, we will get the value of x as 3 and -7.
We know that extraneous solutions are those solutions, which when substituted in the initial equation, the equation does not return an equation.
x=3
[tex]\rm log_4(x)+log_4(x-3)= log_4(-7x+21)[/tex]
[tex]\rm log_4(x3)+log_4(3-3)= log_4(-21+21)\\\\\rm log_4(x)+log_4(0)= log_4(0)[/tex]
As the value of logₐ(0) is undefined, therefore, x=3 is an extraneous solution.

Step-by-step explanation:
Students in Mr. Jacob's class used a number
cube with sides numbered 1 through 6 and a spinner with 4 even-numbered and 4 odd-numbered sections. For each trial, they recorded whether the outcomes for the cube and the spinner were even or odd.
Based on the data in the table, which is closest to the number of times the next 50 trials should result in both the cube and the spinner being even?
A 12
B 25
C 48
D 50
Please explain how you got the answer if you can.. or like a small summary
Answer:
25.
Step-by-step explanation:
the ratio from even to odd is equal. a half chance of getting even 3:6 & 4:8 [ theres 3 even #s on the cube, 3 odds #s on the cube] vice VERSA!! for either even or odd roll. so out of 50, half of 50 is 25. there's a 1:2 chance of even(or in whatever case) 1:2 = 25:50

Trying to factor by splitting the middle term
5.2 Factoring 18x2 - 21x - 5
The first term is, 18x2 its coefficient is 18 .
The middle term is, -21x its coefficient is -21 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 18 • -5 = -90
Step-2 : Find two factors of -90 whose sum equals the coefficient of the middle term, which is -21 .
-90 + 1 = -89
-45 + 2 = -43
-30 + 3 = -27
-18 + 5 = -13
-15 + 6 = -9
-10 + 9 = -1
-9 + 10 = 1
-6 + 15 = 9
-5 + 18 = 13
-3 + 30 = 27
-2 + 45 = 43
-1 + 90 = 89
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

4. A deposit of $1000 is made into a savings account that pays 4% annual interest compounded monthly
a. How much money will be in the account after 6 years?
b. How long will it take for the $1000 to double?
Using compound interest, it is found that:
a) $1,270.70 will be in the account after 6 years.
b) It will take 17.53 years for the $1000 to double.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.In this problem, the parameters are given as follows:
[tex]A(0) = 1000, r = 0.04, n = 12[/tex]
Item a:
Over 6 years, that is t = 6, thus:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]A(t) = 1000\left(1 + \frac{0.04}{12}\right)^{12 \times 6}[/tex]
[tex]A(t) = 1270.7[/tex]
$1,270.70 will be in the account after 6 years.
Item b:
This is t for which A(t) = 2P = 2000, hence:
[tex]2000 = 1000\left(1 + \frac{0.04}{12}\right)^{12t}[/tex]
[tex](1.0033)^{12t} = 2[/tex]
[tex]\log{(1.0033)^{12t}} = \log{2}[/tex]
[tex]12\log{(1.0033)} = \log{2}[/tex]
[tex]t = \frac{\log{2}}{12\log{1.0033}}[/tex]
[tex]t = 17.53[/tex]
It will take 17.53 years for the $1000 to double.
