Answer:
240 degrees
Step-by-step explanation:
Looking at the graph we can see that the first peak is at -30 degrees and the second peak is at 210 degrees.
210 - (-30) = 210 + 30 = 240
B, because to substitute for a variable you have to have an equation to substitute first.
Answer:
<h2>
d = 245</h2>
Step-by-step explanation:
d is directly proportional to the square of a speed v
d = av²
5 = a•10²
5 = 100a
a = 0.05
d = 0.05v²
d = 0.05•70²
d = 0.05•4900
d = 245
