Answer:

A) 9 => 6 => 3 => 0 => -3 => -6

B) Using Formula

$a_{n}= a_{1} + d(n-1)$

=> $a_{n } = 9+3(n-1)$

=> $a_{n}= 9+3n-3\\a_{n} = 3n+6$

Answer: $a_{n }= 3n+6$

Find all solution of the following equation in the interval [0, 2pi) No decimals.

Delicious77 [7]

Step-by-step explanation:

Step 1: Add 2cos(x) to both sides

$7cos(x) + 2cos(x) + 9 = -cos(x) + cos(x)$

$9cos(x) + 9 = 0$

Step 2: Subtract 9 from both sides

$9cos(x) + 9 - 9 = 0 - 9$

$9cos(x) = -9$

Step 3: Divide both sides by 9

$9cos(x) / 9 = -9 / 9$

$cos(x) = -1$

Step 4: Find x

$cos^-^1(-1) = x$

$\pi = x$

Answer: $x = \pi$
