Answer:

r=\frac{9\cos \theta}{\sin^2 \theta}

Step-by-step explanation:

The given equation in rectangular coordinates is;

y^2=9x

We use the relation;

x=r\cos \theta

and

y=r \sin \theta

This implies that;

(r \sin \theta)^2=9(r \cos \theta)

r^2 \sin^2 \theta=9r \cos \theta

Divide through by r to get;

r \sin^2 \theta=9\cos \theta

Divide both sides by \sin^2 \theta

r=\frac{9\cos \theta}{\sin^2 \theta}

nikitadnepr [17]
Hi there! 

Lets dive into the problem, starting with the equation for volume; length x width x height.

If it's 8 x 12 inches, That means the height is 8 and the length is 12. The side, or width, would be x.

The equation should be 8 times 12 times x, or (8)(12)(x).

Anna wants to buy a car in two years and wants to have $10,000 for the purchase. How much will Anna need to deposit today in an
Brut [27]

Answer:

Anna will need to deposit \$9,050.25

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=2\ years\\A=\$10,000\\ r=0.05\\n=12  

substitute in the formula above  and solve for P

10,000=P(1+\frac{0.05}{12})^{12*2}  

10,000=P(1.0042)^{24}  

P=10,000/(1.0042)^{24}    

P=\$9,050.25
