Answer:
f(3/2) = 13√13 ≈ 46.872167
Step-by-step explanation:
Put 3/2 where x is and evaluate.
f(3/2) = 13^(3/2) = 13^(1 +1/2) = 13√13
f(3/2) ≈ 46.872167
EF is tangent to the circle we'll assume; otherwise there's no progress.
Call the center C. ECD is isosceles, formed from two radii and the chord.
Angle CED is complementary to DEF
CED = 90 - 65 = 25 degrees
CDE is congruent, isosceles triangle and all that: CDE=25
That leaves DCE=180-25-25=130 degrees
That's the measure of arc DE as well:
Answer: 130 degrees, choice A
He walked 3 miles in an hour. He would have to also walk 9 laps in 45 minutes to walk the same amount. Not sure what your question is?
