A certain sequence is defined such that the th term in the sequence is equal to n n how much greater is the 10th term th term in the sequence?
Treat this like a function question, only instead of f(n) = n^2 + 1, you’re told that the nth term equals n^2 + 1. Different language, same exact result:
The 7th term will be 7^2 + 1 = 50, and the 10th term will be 10^2 + 1 = 101. 101 is 51 greater than 50.
Final answer:
To find how much greater the 10th term is compared to the nth term in a sequence, we need the sequence's rule. Assuming the rule is n^2, the 10th term is 10^2. The difference would be 10^2 - n^2, but without the value for n or a clear sequence definition, the numerical difference remains unknown.
Explanation:
The question appears to be asking for the 10th and nth terms of a defined sequence, but there seems to be a typo or missing information specifying the rule for the sequence. To find how much greater the 10th term is compared to the nth term, we would first need the explicit formula for the sequence. If the sequence is defined such that the nth term is n2, then the 10th term would be 102, and the nth term would be n2. The difference between the two terms is then 102 - n2. Without the value for n or a proper sequence definition, we cannot find the actual numerical difference.
Which of the following is the absolute value parent function
Answer: Option B |x| and Option C |x|-1
Explanation:
Absolute function is the function that gives the positive value of any variable even of negative variable.
For example if -1 is operated under absolute function that is |-1| gives the value 1
Option A is incorrect because [tex]\frac{1}{x}[/tex] is not written under the denotion of absolute function.
if we say 'x' is an absolute function it will be denoted by |x|.
Option D is incorrect again because it is not written under the denotion of absolute function.
Absolute function or modulus function is same .

What is the missing term in the factorization
To find the missing term in the factorization, we rewrite the equation in the form of ax^2 + bx + c = 0, equate the coefficients and solve for the term. The missing term is -25.
Explanation:
To find the missing term in the factorization, we can rewrite the given equation in a general form of the quadratic equation like ax^2 + bx + c. In our case, this would be:12x^2 - 3(4x^2 - 10x + ?) = −75. Here, 'a' has a coefficient of 12, 'b' is -10 multiplied by 3 (the '3' outside the brackets), and 'c' is ? multiplied by 3. By equating the coefficients on both sides of the equation, we can solve for the missing term '?'. Therefore, the missing term is '? = -75 / 3' or '? = -25'.

Which of the following represents ninth root of x to the seventh power in exponential form?
Answer:
[tex]x^{\frac{7}{9}}[/tex]
Step-by-step explanation:
write ninth root of x to the seventh power in exponential form
[tex]\sqrt[9]{x^7}[/tex]
To write the radical in exponential form we use the below property
[tex]\sqrt[n]{x^a} = x^{\frac{a}{n}}[/tex]
The radical becomes the base of the fraction
[tex]\sqrt[9]{x^7}=x^{\frac{7}{9}}[/tex]
we cannot simplify the fraction.
The given expression in exponential form is
[tex]x^{\frac{7}{9}}[/tex]
Kayla claims that the absolute value of a number is always greater than the number itself. Which statement about her claim is true? Kayla is correct. Any positive number is greater than a negative, and absolute value of a number is always positive. Kayla is correct. The distance between 0 and a number is always more than the number. Kayla is incorrect. The absolute value of a positive number is negative, and negative numbers are less than positive numbers. Kayla is incorrect. The absolute value of 0 or a positive number is equal to the number.
Solution:
The Claim that Kayla has made that absolute value of a number is always greater than the number itself is not true.
The correct statement should be, :
The Absolute value of a number is always greater than or equal to the number itself is a true statement.
Symbolically, | x | ≥ x , if x is a real number.→→True statement
Out of four options, given
Option(D)→ The Claim made by Kayla is incorrect.As, The absolute value of 0 or a positive number is equal to the number.

concert tickets cost $15 for general admission, but only $9 with a student ID. ticket sales total $4500. wirte and graph ab equation that models this situation. explain how to use your graph to find how many student tickets were sold if 200 general admission tickets were sold
The equation is given as 15x + 9y = 4500
The tickets sold when 200 are sold is y = 166.7
How to model the equation
The equation that models this would be
$15x + $9y = $4500
15x + 9y = 4500
If 200 admission tickets were sold we would have
15 * 200 + 9y = 4500
3000 + 9y = 4500
9y = 4500 - 3000
9y = 1500
y = 166.7 please approximate because tickets number has to be whole
The approximated total tickets that were sold is given as 167
Use your graph to check for the value of the corresponding y side if 200 tickets are sold

What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
The two points are: (3, −5) and (−8, 4)
As we know,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The equation of the line:
y - 4 = (4+5)/(-8-3)[x + 8]
y - 4 = (-9/11)[x + 8]
Thus, the equation of the line is y - 4 = (-9/11)[x + 8] which passes through the points (3, −5) and (−8, 4) option (A) is correct.

hope this helps! <3
The solution of the inequality is x ≥ 18.
What is Inequality?Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
We have −1/3x≤−6
