Transform the polar equation to a Cartesian (rectangular) equation: r= 4sinθ

sweet-ann [11.9K]

Answer:

x^2 +y^2 = 4y

Step-by-step explanation:

Using the usual translation relations, we have ...

r^2 = x^2+y^2

x = r·cos(θ)

y = r·sin(θ)

Substituting for sin(θ) the equation becomes ...

r = 4sin(θ)

r = 4(y/r)

r^2 = 4y

Then, substituting for r^2 we get ...

x^2 +y^2 = 4y . . . . . matches the first choice

Write a quadratic function (f) whose zeros are −8 and 2.

WINSTONCH [101]

$\bf x=-8,2\quad 
\begin{cases}
x=-8\implies &x+8=0\\
x=2\implies &x-2=0
\end{cases}
\\\\\\
(x+8)(x-2)=\stackrel{original}{polynomial}\implies x^2+6x-16=y$

Shinya went to the salon. The cost if her haircut was $16.00. He tipped the barber 15%. What was the total cost

Fantom [35]

Total cost=costofhaircut+tip
tip=costofhaircut times percent tip
percent tip=15%

percent means parts out of 100
15%=15/100=0.15

cost of haircut=16
tip=16 times 0.15=2.4

total cost=16+2.4=18.4

total cost=$18.40
