Answer:
Is there suppose to be a question or pic??
Step-by-step explanation:
At the risk of piling on after correct answers have already been given, I’ll offer another way to address this problem. Recall that, if
θ
is real, cos()=Re()
cos
(
θ
)
=
R
e
(
e
i
θ
)
. So, with
A
and
B
real,
(+)+(−)=(+−)=2cos()
e
i
(
A
+
B
)
+
e
i
(
A
−
B
)
=
e
i
A
(
e
i
B
+
e
−
i
B
)
=
2
e
i
A
cos
(
B
)
Finally,
cos(+)+cos(−)=Re((+)+(−))=Re(2cos())
cos
(
A
+
B
)

cos
(
A
−
B
)
=

Answer:
9.055
Step-by-step explanation:
12.7 - 4.705 = 7.995
7.995 + 1.06 = 9.055
There are 8 people, but only 2 pies. So to figure out how much each person gets when divided, which is a keyword, equally. So to put it in fraction form it would be 2/8. If you simplify it you get 1/4. In decimal form, 2/8 and 1/4 both equal 0.25. Hope this helps you to understand it a bit more!
