Answer:
(
5
,
π
)
Step-by-step explanation:
−
5
=
r
cos
θ
88
[
1
]
0
=
r
sin
θ
8888
[
2
]
Squaring [1] and [2]:
25
=
r
2
cos
2
θ
0
=
r
2
sin
2
θ
Adding [1] and [2]:
25
=
r
2
cos
2
θ
+
r
2
sin
2
θ
Factor:
25
=
r
2
(
cos
2
θ
+
sin
2
θ
)
25
=
r
2
⇒
r
=
±
5
( use
r
=
5
)
Operating cost
= Gas/Oil + Repair/Maintenance cost
= $1,700+ $650
= $2350
Miles driven
= $2350 ÷ $0.14
= 16,785.71
= 16,786 (round off)
Answer is A
yes it would be 24 feet tall
The answer
let p' be the corresponding angle of the angle p (that is because of the prallelism and the transversal, look the image)
but p' and p are correspondant angles implies p'=p,
looking at the figure, p' and q are opposite angles
so q=p' and p'=p implies q=p
the answer is
<span>p = q</span>
