The slope of the line is 2/3, so the angle is arctan(2/3) ≈ 33.69°.
Answer:
4 units right and 3 units up.
Step-by-step explanation:
A heptagon has 7 sides so it would be a pentagon (which has 5 sides)
Answer:
A, D, and E

Answer:
Radius of convergence of power series is
Step-by-step explanation:
Given that:
n!! = 1⋅3⋅5⋅⋅⋅⋅(n−2)⋅n n is odd
n!! = 2⋅4⋅6⋅⋅⋅⋅(n−2)⋅n n is even
(-1)!! = 0!! = 1
We have to find the radius of convergence of power series:
Power series centered at x = a is:
Applying the ratio test:
Applying n → ∞
The numerator as well denominator of are polynomials of fifth degree with leading coefficients:
