Evaluate each geometric series described<br> 1-4+16-64...., n=6

xz_007 [3.2K]

Answer:

- 819

Step-by-step explanation:

The sum to n terms of a geometric series is

$S_{n}$ = $\frac{a(r^n-1)}{r-1}$

where a is the first term and r the common ratio

Here a = 1 and r = - 4 ÷ 1 = - 4, thus

$S_{6}$ = $\frac{1((-4)^6-1)}{-4-1}$ = $\frac{4096-1}{-5}$ = $\frac{4095}{-5}$ = - 819

F(x)=−6x+7, evaluate f(x+2)

lakkis [162]

Answer:

f(x+2) = - 6x - 5

Step-by-step explanation:

As we have f(x) =- 6x + 7, then we also have f(x+2) = - 6(x+2) + 7 = - 6x - 12 + 7 = - 6x - 5.
