Answer: hello!
i think the answer is angle 2
Mesure of inscribed angle: mesure angle LMN = mesure ARC (MLN)/2
Hence angle MLN = 64°
Yes you used the chain rule properly to follow the correct steps to get the right answer. Great job.
If you wanted, you can come up with examples for f(x) and g(x) to help confirm the answer. A quick way to do this is to use something like GeoGebra to help graph the two expressions and you'll notice that the curves match up perfectly (indicating equivalent expressions). Note: GeoGebra can handle derivatives through the Derivative[] comand or you can type the function in the input bar with a tickmark after it to tell GeoGebra to derive the function.
Answer:
60 miles per hour
Step-by-step explanation:
Use speed = distance / time
Speed = 240 / 4
240 / 4 = 60
Speed = 60
rise to run is the slope of the line. it is also written as rise over run
