Arrange the summation expressions in increasing order of their values.

nalin [4]

We'll solve for each one of them:

$\sum_{i=1}^{4}4(5)^{i-1} = (4(5)^{1-1}) + (4(5)^{2-1}) + (4(5)^{3-1}) + (4(5)^{4-1})$
$=4+20+100+500 = 624$

$\sum_{i=1}^{5}3(4)^{i-1} = (3(4)^{1-1}) + (3(4)^{2-1}) + (3(4)^{3-1}) + (3(4)^{4-1}) + (3(4)^{5-1})$
$=3+12+48+192+768=1023$

$\sum_{i=1}^{2}5(6)^{i-1} = (5(6)^{1-1}) + (5(6)^{2-1})$
$=5+30=35$

$\sum_{i=1}^{4}5^{i-1} = (5^{1-1})+(5^{2-1})+(5^{3-1})+(5^{4-1})$
$=1 + 5+ 25+125 = 156$

So, our totals are: 624, 1023, 35, and 156. So clearly, 1023 > 624 > 156 > 35. W can write it as (your answer):

$\sum_{i=1}^{2}5(6)^{i-1}$

Hope this helps! If anything is confusing, you can always DM me.

A charity distributed 80 000 emergency packages during 2018. This number is

Likurg_2 [28]

Answer:

121670

Step-by-step explanation:

The number of packages can be defined with the function:

P(t) = P(t-1)*1.15 where t = the years and 1.15 represents the 15% increase.

Packages during 2018: P(2018) = 80000

Packages during 2019: P(2019) = P(2018)*1.15 = 92000

Packages during 2020: P(2020) = P(2019)*1.15 = 105800

Packages during 2021: P(2021) = P(2020)*1.15 = 121670

The variables x and y are related proportionally. when x= 4 ,y=10 . find y when x=18

egoroff_w [7]

45. divide the first set of x and y by 2 then multiply by 9 to get 45 for y and 18 for x
