Base on the visibility formula v = 1.225√a, the altitude at which Dereck is hang gliding is 7.4 miles
<h3>How to find altitude using visibility formula?</h3>
The visibility formula is given as follows:
v = 1.225√a
where
- a = altitude
- v = visibility
Therefore,
v = 67.1 miles
v = 1.225√a
67.1 = 1.225√a
divide both sides by 1.225
√a = 67.1 / 1.225
√a = 54.7755102041
square both sides
√a² = √54.7755102041
a = 7.40104789878
a = 7.4 miles

Answer:
30/1000
Step-by-step explanation:
red has a chance of 3/10
purple has a chance of 2/10
yellow has a chance of 5/10
for probability, multiply the denominators together, and the numerators together
3*2*5 = 30
10*10*10 = 1000
So the probability of picking red, then purple, and then yellow with replacement is 30 of 1000
Hope this helps!
7/10=70/100=70%, so the answer is seventy-percent.
Answer:
y = -34x + 62
Step-by-step explanation:
<u>Use the point slope form: (y - y1) = m(x - x1)</u>
<u />
(y - (-6) = -34(x - 2)
y + 6 - 6 = -34x + 68 - 6
y = -34x + 62
Answer: y = -34x + 62
