Answer:
y = (x/(1-x))√(1-x²)
Step-by-step explanation:
The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:
x = r·cos(θ)
y = r·sin(θ)
x² +y² = r²
__
r = sec(θ) -2cos(θ)
r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)
r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²
(x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations
x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor
y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)

__
The attached graph shows the equivalence of the polar and rectangular forms.
Answer:
$690
Step-by-step explanation:
all you have to do is multiply $345 by 2 since she spent half of her money
OK you have a total of 400 ones and your asking how many hundreds..
this is a 100 and you 400 of ones so think if u have 400 ones and each hundred equals 100 then you have 4 hundreds cause you have ..
400 ones and
4 hundreds
hoped this helped!!!
3 1/8 = 25/8
25 and 8 have no common factors, so 25/8 is in simplest form.
