The slope of the graph is –1. which statement describes how the slope is related to the burning of a candle? candle height increases 1 cm per hour candle height decreases 9 cm per hour candle is 1 cm tall candle burns down 1 cm per hour

candle burns down 1 cm per hour

Step-by-step explanation:

Slope is rate of change.  It describes how the dependent variable, y, changes as the independent variable, x, increases.

A slope of -1 means that for every increase by 1 on the x-axis, the y values decreases by 1.

In this situation, our variables would be candle height and time; time would be independent, so it would be the x variable.  Candle height would be dependent, so it would be the y variable.

This means that for every hour increase in time, the candle's height decreases by 1 cm.

it would be (D) candle burns down 1 cm per hour

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.
