If a point
(
x
,
y
)
is written as
(
r
,
θ
)
in polar coordinates, then
x
=
r
o
s
θ
and
y
=
r
sin
θ
.
As such in polar form equation
x
=
−
3
can be written as
r
cos
θ
=
−
3
or
r
=
−
3
cos
θ
12.4 / 6.2 = 2
so other side of enlarged rectangle = 1.8 x 2 = 3.6
Perimeter of enlarged rectangle = 2(3.6 + 12.4) = 32
Answer: 32 feet
------------------------
Another way to do:
12.4 / 6.2 = 2
SF = 2
The original rectangle has a perimeter of 16
Perimeter of the enlarged rectangle = 16 x 2 = 32
Answer: 32 feet
Which one?
Go to www.mathpapa.com and put this in "<span>y = <span><span>−<span>2x </span></span>− 4</span></span>; <span>y = <span><span>2x </span>− <span>4" That is 1st
</span></span></span>For 2nd put this in "y = 1/2x + -11/2; y = -2x + 2"
Answer:
the answer will be 5.
Step-by-step explanation:
That sequence is not geometric or arithmetic
it is not changing or doing anything it is just remaining the same.
it would be geometric if it was:
1+1-1+1-1+1........
