Answer:

b. 4x^2+3y^2-24y-144=0

Step-by-step explanation:

The given equation is;

r=\frac{-72}{12+6\sin(\theta)}

Cross multiply;

r(12+6\sin(\theta)=-72

Expand;

12r+6r\sin(\theta)=-72

Divide through by 6;

2r+r\sin(\theta)=-12

2r=-12-r\sin(\theta)

Substitute;

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

2\sqrt{x^2+y^2}=-12-y

Square both sides;

(2\sqrt{x^2+y^2})^2=(-12-y)^2

4(x^2+y^2)=144+24y+y^2

4x^2+4y^2=144+24y+y^2

Simplify;

4x^2+3y^2-24y-144=0

Dvinal [7]
1 day = 225 liters
2 days = 450 liters

I don't think it is proportional..

Proportional is like..

Find x and y plz help :(
liraira [26]

Answer:

D. x = 5.4, y = 6.67

Step-by-step explanation:

The triangles are similar as per problem description, so the ratios match:

y/5 = 4/3

x/3 = 9/5

let's solve:

y/5 = 4/3

3y/5 = 4

3y = 20

y = 6.(6)

x/3 = 9/5

5x/3 = 9

5x = 27

x = 5.4

The graph of g(x) is a reflection and translation of<br> f(x) = ³√x.
yaroslaw [1]

The function g(x) will be given as g(x) = – ∛(x – 1). Then the correct option is D.

The complete question is attached below.

<h3>What is a transformation of geometry?</h3>

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Reflection does not change the size and shape of the geometry.

Translation does not change the size and shape of the geometry.

The function f(x) is given below.

f(x) = ∛x

Then the function of the g(x) will be

g(x) = – ∛(x – 1)

Then the correct option is D.

More about the transformation of geometry link is given below.
