If x^(3/5) = 1.84, then x^2 = ? Show Work. A.) 7.63 B.) 10.40 C.) 21.15

svetlana [45]

X^(3/5) = 1.84

x^(3/5) = (1.84)

Raise both sides of the equation to (5/3).

This is so that on the side with x, 3/5 * 5/3 = 1.

(x^3/5 )^5/3 = (1.84)^(5/3)

x^(3/5 * 5/3) = 1.84^(5/3)

x^1 = 1.84^(5/3)

x = 1.84^(5/3)

But remember we are solving for x^2.

x = 1.84^(5/3)

x^2 = (1.84^(5/3))^2

x^2 = 1.84^(5/3 *2 )

x^2 = 1.84^(10/3)

Use a calculator here.

x^2 = 1.84^(10/3) ≈ 7.63

Option A.

Cheers!

Earth orbits the sun in an elliptical pattern. The equation of Earth's path is.... where the measurements represent millions of

Triss [41]

General equation of Ellipse centered at (h,k) is given as

$\frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} =1\\$

where a is the radius along x-axis

and b is radius along y-axis.

Given : The equation of elliptical path of Earth as

$\frac{(x+2.5)^{2}}{22350.25} + \frac{y^{2}}{22344} = 1\\$

Comparing the equation with the general equation, we get

(h,k) as (-2.5,0)

a = $\sqrt{22350.25} = 149.5$

b = $\sqrt{22344} = 149.48$

We have the Sun located at the coordinate (0,0).

Hence, the distance between Sun and Earth in July = 149.5 + 2.5 =152

∴ Earth's distance from the Sun in July is 152 million kilometers.

Can someone help me?

Answer:

Step-by-step explanation:

To do this, we must use the unit circle. At the angle $\frac{\pi }{6}$ the coordinate pair is ( $\frac{\sqrt{3} }{2}$ , $\frac{1}{2}$ ) and the hypotenuse is 1
