Using the features, a piece-wise function is defined, and the graph is sketched at the end of this answer.
A piece-wise function is a function that has <u>multiple definitions</u>, depending on the value of the input.
He starts at 0 feet, and reaches a maximum elevation of 800 feet in 30 minutes, with a steady(linear) increase thus, for the first 30 minutes, the definition is:
![h(t) = \frac{800}{30}t, 0 \leq t < 30](https://tex.z-dn.net/?f=h%28t%29%20%3D%20%5Cfrac%7B800%7D%7B30%7Dt%2C%200%20%5Cleq%20t%20%3C%2030)
For the next 5 minutes, he stops to rest, at the maximum elevation of 800 feet, thus, the definition is:
![h(t) = 800, 30 \leq t < 35](https://tex.z-dn.net/?f=h%28t%29%20%3D%20800%2C%2030%20%5Cleq%20t%20%3C%2035)
For the final 20 minutes, he descends 800 meters, at a linear rate, thus:
![h(t) = 800 -\frac{800(t-35)}{20} = 800 - 40(t - 35), 35 \leq t \leq 55](https://tex.z-dn.net/?f=h%28t%29%20%3D%20800%20-%5Cfrac%7B800%28t-35%29%7D%7B20%7D%20%3D%20800%20-%2040%28t%20-%2035%29%2C%2035%20%5Cleq%20t%20%5Cleq%2055)
Using these definitions, the graph is sketched at the end of this answer.

Converting percentage to a decimal :
50%= 50 / 100 = 0.5
What is 50% of 15
=50% * 15
=0.5 * 15
=7.5
Answer:
X≤3
Step-by-step explanation:
This is because the arrow is moving down the number line
I thinks it C, this a difficult question but idk, that my closest guess...
So u already know that the radius is half of the circle which in this case is 28 mm. And both circles at the top touch both sides of the rectangle.
Process:
28x4=112.
This is the top side, but because you could fit 2 circles at the top and you know the measurement, it is common sense to think that it would be the same on the other side. So the area of the square/ rectangle:
112x112= 12,534 mm
