If Michael starts with 55 and saves 20 per week. and hema starts with 40 ans saves 20 per week. they'll never have the exact same amount.
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
)
=
R
e
(
e
i
(
A
+
B
)
+
e
i
(
A
−
B
)
)
=

Answer:
64
Step-by-step explanation:
8 x 8 = 64 or 16 x 4 = 64
Answer:
The cube of first six natural numbers are
1, 8, 27, 65, 125, 216
Step-by-step explanation:
Natural Numbers are known as 1, 2, 3, 4, ..., ∞
Now,
For Cube of first six natural numbers
1³ = 1
2³ = 8
3³ = 27
4³ = 64
5³ = 125
6³ = 216
Thus, The cube of first six natural numbers are
1, 8, 27, 65, 125, 216
