Answer:
The roots (zeros) are the
x values where the graph intersects the x-axis. To find the roots (zeros), replace and with 0
and solve for
x.
Exact Form:
x=−2±√52
Decimal Form:
x=0.11803398
…,−2.11803398
…
Step-by-step explanation:
Negative
basically
negative means change sign
positive means do nothing
change sign times do nothing=change sign=negative
basically
(+)(+)=(+)
(-)(-)=(-)
(+)(-)=(-)
(-)(+)=(-)
and
(+)/(+)=(+)
(-)/(-)=(-)
(+)/(-)=(-)
(-)/(+)=(-)
answer is negative
BD is parallel to AE because the lines are not touching each other, if you extend the lines if BD and AE they would not touch therefore making BD and AE parallel.
Cos(sin⁻¹(³/₅))
cos(36.87)
