Is y=arcsec(1) equivalent to 0? Thanks!
1 answer:
arcsin(1) = 90 degrees
arccos(1) = 0
arctan(1) = 45 degrees
When you say "arcsec(1)", do you mean the angle whose secant is 1 ?
Since the secant is 1/cosine, if the secant of your angle is 1, then
its cosine is also 1, and the angle is zero (and 360).

Answer:
68%
Step-by-step explanation:
Calculate percentage change
from V1 = 82 to V2 = 138
(V2−V1)|V1|×100
=(138−82)|82|×100
=5682×100
=0.682927×100
=68.2927%change
=68.2927%increase
=68%
1/3y + 28 = -5
Subtract 28 from both sides:
1/3y = -33
Multiply both sides by 3:
y = -99
