Help please ASAP!!
Fittoniya [83]

Answer:

\displaystyle 702

Step-by-step explanation:

we are given a exponential function

\displaystyle f(x) =  {3}^{x + 1}  - 22

where x represents the number and f(x) represents the amount

we are also given that when x is 3 then f(x) is 59 likewise when x is 6 then f(x) is 2165

to figure out the average rate of change between 3 and 6 we can consider the average rate of change formula given by

\displaystyle m =  \frac{ f(x)_ {2} -  f(x)_{1} }{ x_{2} -  x_{1} }

substitute what we have:

\displaystyle m =  \frac{ 2165 -  59 }{6 - 3 }

simplify substitution:

\displaystyle m =  \frac{2106 }{3 }

simplify division:

\displaystyle m =  702

hence, the average rate of change between 3 and 6 is <u>7</u><u>0</u><u>2</u>

Show that the series is convergent by the alternating series test, and find the number of terms necessary to estimate the sum of
Murljashka [212]

Answer:

6 terms

Step-by-step explanation:

2 − 2/4 + 2/9 − 2/16 + ...

∑ (-1)ⁿ⁺¹ 2 / n²

Applying alternating series test:

lim(n→∞) 2/n² = 0

2/(n+1)² < 2/n², so the series is decreasing.

Therefore, the series converges.

2/(n+1)² < 0.05

(n+1)²/2 > 20

(n+1)² > 40

n+1 > 6.32

n > 5.32

n = 6
