1 hr 40 mins = 5/3 hours
average speed = 117 / 5/3 = 117*3 / 5 = 70.2 kph.
2. speed = distance / time
70.2 = 19.2 / time
time = 19.2 / 70.2 = 0.2735 hours = 16.5 minutes answer
The functions have been arranged in ascending order from the least to the highest value below
- 3x
- 3x + 8
- x^2
- x^2 + 6
- 4^x
- 4^x + 3
<h3>What is meant by ascending order?</h3>
This is used in mathematics as well as other disciplines to explain the order by which values are arranged. This arrangement is usually done in such a way that the smallest value would come first and continue to climb till we get to the value that is the highest.
The values here have been arranged in this order in such a way that the smallest values came first while the bigger values are at the end.

Find LCM and simplify
Answer:
Step-by-step explanation:
An altitude is a line segment that meets the side opposite the vertex at right angles. The line also has to go through the vertex.
The only line that does both those things is DE.
You can do foil method first, to make it easier and to avoid product rule,
y= 45x^4 - 15x³ + 25x² - 72x² + 24x - 40
Simplify like terms,
y= 45x^4 - 15x³ - 47x² + 24x - 40
Now, find derivative,
dy/dx = 180x³ - 45x² - 94x + 24
