The answer is simple 12h+18!!
goal:tan^5x=tanx(sec²x-2sec²x+1)
proof: from l.h.s to r.h.s
tan^5x=(tanx)^5=((tanx)(tan²x)(tan²x))
from trigonometry identity
(tan²x)=sec²x-1
tan^5x=(tanx(sec²x-1)(sec²x-1))
=(tanx(sec^4x-sec²x-sec²x+1))
=(tanx(sec^4x-2sec²x+1))
proved
Answer:
14/-15
Step-by-step explanation:
<em>(y2 - y1) / (x2 - x1) = slope</em>
= (-6 - (-20)) / (-17 - (-2))
= 14 / -15
Slope = 14/-15
Answer:
A=6143.54( to the nearest dollar A=6144)
Step-by-step explanation:
A=Pe^(r(t))
P=3100 r=0.036 t=19
A=3100e^0.036(19)
A=3100e^(0.684)
The answer to your question is 13/20, .65, 65%
