It's asking on the slope of it for the f⁻¹(x), so you have to get the inverse firstly, then we can simply get the derivative by implicit differentiation,
Sorry but do you have the image of the piece wise function?
Answer: Hi!
So first, I'm going to convert "350 below ground level" to -350, as this is what "below ground level" represents.
Now, we should find the total distance traveled. Take the absolute value of -350 (350) and add it to 10, the metres above ground level. This is 360.
We already know the rate of travel; 6m/min. All we have to do now is divide the total distance (360) by the rate of travel (6)!
360 ÷ 6 = 60
So, it took 60 minutes, or one hour, for the elevator to travel down the shaft!
Hope this helps!
There are many solutions. Choose any 'x', and then choose 'y' which is greater than 7 and greater than the double of 'x'.
When writing the ordered pair, remember that 'x' comes first.
Some examples: (0,8), (1,10), (-3,9), etc.
You can interpret this graphically. The points that solve 'y>2x' are those above the line 'y=2x', and the solutions to 'y>7' are those above the line 'y=7' (which is an horizontal line). Hence the solution to the system of inequalities is the intersection of those two regions. Have a look at the illustration:
Answer:
$150
Step-by-step explanation: 11.25 divided by tax rate of 7.5 % equals 150
