Answer:

the last one 2x-⁴y⁶

Step-by-step explanation:

-4 : - 2 = 2

x-³ : x = x-³-¹ = x-⁴

y⁴ : y-² = y⁴-(-²) = y⁴+² = y⁶

final

2x-⁴y⁶

Move all terms that don't contain y to the right side and solve.
y = - x/3 + 14/3
Hope this helps! :)

Answer:

a. (3x^4 + 6 ) + (2x^2)

b. (X^3 ) + (-x -7)

c. (4.6x^4) + (-1.5x^2)

Step-by-step explanation:

For the first one, we have to write to polynomials, which equal 3x^4 + 2x^2 +6

One possible solution is (3x^4 + 6 ) + (2x^2)

For b, we can do,

(X^3 ) + (-x -7)

And finally for c, we can write,

(4.6x^4) + (-1.5x^2)

The radii of two circles are in the ratio of 3 to 1. Find the area of the smaller circle if the area of the larger circle is 27

Naddik [55]

ANSWER
$3\pi sq.\: in.$

EXPLANATION

Let R be the radius of the bigger circle and r, be the radius of the smaller circle.

Then their ratio is given as,

$R:r=3:1$

We can rewrite it as fractions to get,

$\frac{R}{r} = \frac{3}{1}$

We make R the subject to get,

$R = 3r$

The area of the bigger circle can be found using the formula,

$Area=\pi {r}^{2}$

This implies that,

$Area=\pi ({3r})^{2}$

$Area=9\pi {r}^{2}$

But it was given in the question that, the area of the bigger circle is 27π.

$27\pi=9\pi {r}^{2}$

We divide through by 9π to get,

$3 = {r}^{2}$

This means that,
$r = \sqrt{3}$

The area of the smaller circle is therefore

$= \pi {( \sqrt{3}) }^{2}$

$= 3\pi$
