Answer:
10.8 kilograms
Step-by-step explanation:
A = 4,
we denote one side of the rectangle with
a
, and the other with
b
we can write, that:
a
⋅
b
=
16
so we can write, that
b
=
16
a
Now we can write perimeter
P
as a function of
a
P
=
2
⋅
(
a
+
16
a
)
We are looking for the smallest perimeter, so we have to calculate derivative:
P
(
a
)
=
2
a
+
32
a
P
'
(
a
)
=

+
(

P
'
(
a
)
=
2
−

a

=

a

−

a

The extreme values can only be found in points where
P
'
(
a
)
=
0
P
'
(
a
)
=
0
⇔
2
a

or
a

Since, length is a scalar quantity, therefore, it cannot be negative,
When

b

b

Answer:
The value on the In side: 2
The first value on the Out side: 87
The second value on the Out side: 93
Step-by-step explanation:
First, I started by finding the differences by each step on both sides. I noticed that they increased together. 45-27 is 18, and it mirrored on the other side. 27-9 is 18, and it mirrored. By this I mean that 81-63=18 as well as 63-45=18. So I followed this pattern 45-38=7, so 9-7=2, and that gives us our first answer. 51-45=6, so 81+6=87, gives us our second. 57-51=6, so 87+6=93, and this gives us our third.
Sorry, I don’t think you wrote out the question correctly, making it difficult for me to help you.
Answer:
a total of 129 minutes
Step-by-step explanation:
$17.48 - $2 fixed monthly fee = $15.48
