Q6: Which is the graph of the polar equation r=1/1-sin theta.
AveGali [126]

Answer:

The correct answer is C.

Step-by-step explanation:

The given equation is;

r=\frac{1}{1-\sin(\theta)}

This implies that;

r(1-\sin(\theta)=1

r-r\sin(\theta)=1

Let us write in Cartesian coordinates by substituting;

r=\sqrt{x^2+y^2} ,y=r\sin(\theta)

\sqrt{x^2+y^2}-y=1

\sqrt{x^2+y^2}=y+1

Square both sides;

(\sqrt{x^2+y^2})^2=(y+1)^2

This implies that;

x^2+y^2=y^2+2y+1

x^2=2y+1

y=\frac{1}{2}x^2-\frac{1}{2}

This is an equation of a parabola that opens upwards with a  y-intercept of -\frac{1}{2}.

The correct choice is C

Solve 3^2x-5=81<br> Please show work
Strike441 [17]
Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9

Hope this helps!

Explain how you could use a number line to determine -5 -(-3)<br><br> What is the difference?
siniylev [52]

Answer:

-2

Step-by-step explanation:

Start on -5 on the left side of the number line, jump from -5 three times to the right of the number line since ( - - ) means to add. As you jump draw "bridges" and by the time you have completed the amount of jumps you have to do you'll end up with a difference of -2.
