Explanation:
Factorizing your equation we get
cot
(
x
)
=
0
so
cos
(
x
)
=
0
we get the following Solutions in the given interval
x
=
π
72
or
x
=
3
π
2
for the second case we get
cot
(
x
)
=
−
1
so
cos
(
x
)
=
−
sin
(
x
)
and we get
x
=
3
π
4
or
x
=
7
π
4
Hint:
To get the Solutions of the last equation you can use
√
sin
(
x
+
π
4
)
=
0

Answer:
I'm going to assume that the question was $1.99 × 10 because $1.99 $1.99; × 10 is not possible, so if that was the question, the answer would simply be false. The answer I got for $1.99 × 10 was 19.9
Answer: 19.9
Answer:
Width = 9
Length = 13
Step-by-step explanation:
width = w
length = L
w(2) - 5 = L
w + w + L + L = 44
44 + 5 + 5 = 54
54/6 = 9
9(2) = 18 - 5 = 13
w = 9
l = 13
Check:
9 + 9 + 13 + 13 = 44
9(2) = 18 - 5 = 13
