(a)
Substitute <em>x</em> = 3 tan(<em>t</em> ) and d<em>x</em> = 3 sec²(<em>t </em>) d<em>t</em> :
(b) The series
converges by comparison to the convergent <em>p</em>-series,
(c) The series
converges absolutely, since
That is, ∑ (-1)ⁿ (<em>n</em> ² + 9)/<em>e</em>ⁿ converges absolutely because ∑ |(-1)ⁿ (<em>n</em> ² + 9)/<em>e</em>ⁿ| = ∑ (<em>n</em> ² + 9)/<em>e</em>ⁿ in turn converges by comparison to a geometric series.
Answer:
3 (10-a) = 4 i think
Step-by-step explanation:
Answer:
z³ = 64
z³=4³
since power is equal, base will be same
z=4
Step-by-step explanation:
Answer:
10x^2+76x+144
Step-by-step explanation: ayo if i helped thank me i hoped i did have a great day
<span>First, you need to take the 15% off from the $120 so it will make it easier for you to calculate later. Since there is 15% off, your $120 becomes only $102. Since your keyboards only costs $102 each now, you just have to multiply the number of keyboards you wanted to the less price. $102 multiplied by 24 keyboards is equals to $2,448. We don’t have to add taxes because it is stated that we are just looking for SUBTOTAL before taxes. The answer is A. $2,448. <span>
