The temperature fell 4 degrees in the last hours. now it is 21 degrees. write and solve an equation to find the temperature it was 1 hour ago.

20

Step-by-step explanation: you trying to see how much you got and you get 20 due to the fact it’s asking for how much did you get when it dropped 1

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.

the answer is: -22 also a
