Find the 12th term of each sequence. a9= 120, a14=195

Luda [366]

The general formula for an Arithmetic Progression is :

$\boxed {\boxed {T_n = a_1 + (n-1)d}}$

$\text {Given that } a_9 = 120,$

$T_9 = a_1 + (9 - 1)d = 120$

$a_1 + 8d = 120 \text { ------------------(1)}$

$\text {Given that } a_{14} = 195,$

$T_9 = a_1 + (14 - 1)d = 195$

$a_1 + 13d = 195 \text { ------------------(2)}$

Equation (2) - Equation (1) :

$13d - 8d = 195 - 120$

$5d = 75$

$d = 15$

Substitute d = 15 into Equation (1) :

$a_1 + 8(15) = 120$

$a_1 = 120 - 120$

$a_1 = 0$

$\text {Substitute }a_1 = 0 \text{ and d = } 15,$

$\boxed { \boxed { T_n = 15(n -1) }}$

Find 12th term :

$T_{12} = 15(12 -1) = 165$

$\boxed {\boxed {\text {Answer: The 12th term is 165.}}}$

What is the relationship between the factors and the graph of a polynomial equation??

bija089 [108]

Answer:

Each intercept corresponds to a zero of the polynomial function and every zero yields a factor.

Step-by-step explanation:

Each intercept corresponds to a zero of the polynomial function and every zero yields a factor, so we can now write the polynomial in factored form. Graphs behave differently at various intercepts. Sometimes, the graph will cross over the horizontal axis at an intercept. Other times, the graph will touch the horizontal axis and bounce off.

What Is the slope of a line perpendicular to y=x-6

postnew [5]

The slope of a line that is perpendicular to y = x - 6 means that the slope has to be a negative reciprocal of the original slope

That means the slope of the line that is perpendicular to y = x - 6 is '-1'
