(−2, 4)

The function is positive in intervals

A function is positive in intervals where the graph lies above the axis.

A function is negative in intervals where the graph lies below the axis.

In intervals , the graph lies below the axis.

In intervals , the graph lies above the axis.

So, the function is positive in intervals

Positive is when the lines are above the X axis

 in this graph it is positive from  [−8, −6) and (−2, 4)

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

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.
