Shota is a dangerous fellow who likes to go rock climbing in active volcanoes. One time, when he was 30 meters below the edge of
2 answers:
Answer:His rate of climbing = 5 meter /second and total time to reach the edge of volcano = 6 second
Step-by-step explanation:
Here, According to the question,
The total distance he would cover= 30 meter.
The distance covered by him in 4.5 second = 30 - 7.5= 22.5 meter.
Thus, his speed = = 5 m/s ( because speed = distance/ time)
Since, the remaining distance he has to cover= 7.5 meter
So, the time taken by him to cover the distance= 7.5/5= 1.5 seconds
Therefore the total time taken to cover the distance of 30 meter,
T= 4.5 + 1.5 = 6 second.

Using linear function concepts, it is found that:
- a) It costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.
- b) f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.

A <em>linear function </em>has the format given by:
In which:
- m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
The equation for the cost of h kilowatt hours (kWh) of electricity used in excess of 250 kWh is of:
Item a:
- The slope is of
, which means that it costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.
Item b:
250 + 90 = 340.
f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.
