Answer:

-89

Step-by-step explanation:

K(t) = K(-7)

10 is being multiplied by t. t = -7

so:

10(-7) = -70

-70 - 19 = -89

Hope this helps!

Answer:

4/3

Step-by-step explanation:

Slope is rise over run. So how far do you rise to get up to 3 from -1. Put that over the run, (once you go up that many how far do you run?) Put that as a fraction and simplify if needed.

An arithmetic sequence is defined by the general term tn = 19 - (n - 1)18, where n ∈N and n ≥ 1. What is the recursive formula o

vovikov84 [41]

$t_n=19-18(n-1)$
$t_{n-1}=19-18(n-2)$
$\implies t_n-t_{n-1}=-18(n-1)+18(n-2)$
$\implies t_n=t_{n-1}-18n+18+18n-36$
$\implies t_n=t_{n-1}-18$

So the recursive formula is

$\begin{cases}t_1=19\\t_n=t_{n-1}-18&\text{for }n>1\end{cases}$
