Each term is 0.19 more than its predecessor. You have

$0.35=0.16+0.19$

$0.54 = 0.35+0.19$

So, we can assume that the next terms will be

$0.73 = 0.54 + 0.19$

$0.92 = 0.73 + 0.19$

To find the answer you add 16 + 16 + 3 which equals 35 so the next two would be 0.73 and 0.93 if you continue adding 16 + 3 from the last givin example which in this case would be 54

Convert the Cartesian equation (x 2 + y 2)2 = 4(x 2 - y 2) to a polar equation.

SashulF [63]

ANSWER

${r}^{2} = 4 \cos2\theta$

EXPLANATION

The Cartesian equation is

${( {x}^{2} + {y}^{2} )}^{2} = 4( {x}^{2} - {y}^{2} )$

We substitute

$x = r \cos( \theta)$

$y = r \sin( \theta)$

and

${x}^{2} + {y}^{2} = {r}^{2}$

This implies that

${( {r}^{2} )}^{2} = 4(( { r \cos\theta) }^{2} - {(r \sin\theta) }^{2} )$

Let us evaluate the exponents to get:

${r}^{4} = 4({ {r}^{2} \cos^{2}\theta } - {r}^{2} \sin^{2}\theta)$

Factor the RHS to get:

${r}^{4} = 4{r}^{2} ({ \cos^{2}\theta } - \sin^{2}\theta)$

Divide through by r²

${r}^{2} = 4 ({ \cos^{2}\theta } - \sin^{2}\theta)$

Apply the double angle identity

$\cos^{2}\theta -\sin^{2}\theta= \cos(2 \theta)$

The polar equation then becomes:

${r}^{2} = 4 \cos2\theta$

Answer:

5. 1

6. Kari is not correct.

Step-by-step explanation:

5. All like terms can be combined. There will be one term remaining after they are.

___

6. The appropriate factoring is x(x+1). This is not the same as x(2x+1).

In order to show equivalence, you need to show that the expressions produce the same result for as many different values of x as the degree of the expression plus 1. That is, you'd need to show equivalence for 3 different values of x, as a minimum for this second-degree expression.
