Challenge in the first week of July, a record 1,020 people went to the local swimming pool. In the second week, 110 fewer people went to the pool than in the first week. In the third week, 145 more
people went to the pool than in the second week. In the fourth week, 239 fewer people went to the
pool than in the third week. What is the percent decrease in the number of people who went to the
pool over these four weeks?

step-by-step explanation:

srry idk

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
