Answer:
y equals x
Step-by-step explanation:
With a dial action, although the dilated image may get smaller or larger the angles/ slope of lines would remain the same.
Slope = change I. Y over the change in X
Slope = (5-4) /(3-2) = 1/1 = 1
Slope = 1
Answer:
x^2+y^2=(x^2+y^2-2y)^2
Step-by-step explanation:
Here we are given that
r=1+2sin
we know that the polar cordinates are represented as
x=rsin
y=rcos
Also squaring both and adding them gives you ,
Hence
also r=1+2sin
1+2sin =
Also ,
r = r=1+2sin
also sin =
Hence replacing sin we get

Answer:
10.5
Step-by-step explanation:
ΔXYZ is similar to ΔABC. So the corresponding sides are proportional:
XY / AB = XZ / AC = YZ / BC
We want to find length AB, so we can either use the first proportion:
7 / k = 3 / 4.5
Or we can use the second proportion:
7 / k = 6 / 9
Either way, we'll get the same answer. I'll use the second proportion. Cross multiplying:
6k = 63
Dividing:
k = 10.5
