The equation that models the movement of Tanus around Ini, where Ini is located at (0, 0) is x^2/75^2 + y^2/37.5^2 = 1

<h3>Write an equation that models the movement of Tanus around Ini, where Ini is located at (0, 0)</h3>

The given parameters are:

The length of Tanus’ major axis = 150 million miles

The length of its minor axis = 75 million miles

The center of the ellipse = (0, 0) --- the location of Ini

When the coordinate of the center of an ellipse is (0, 0), the standard form of the ellipse is represented as:

x^2/a^2 + y^2/b^2 = 1

Where:

Length of the major axis = 2a

Length of the minor axis = 2b

This means that:

2a = 150 and 2b = 75

Divide both sides of 2a = 150 by 2

a = 75

Divide both sides of 2b = 75 by 2

b = 37.5

Substitute b = 37.5 and a = 75 in the standard form of the ellipse represented as: x^2/a^2 + y^2/b^2 = 1

x^2/75^2 + y^2/37.5^2 = 1

Hence, the equation that models the movement of Tanus around Ini, where Ini is located at (0, 0) is x^2/75^2 + y^2/37.5^2 = 1

I dont understand this
MrRa [10]

Answer: First option.

Step-by-step explanation:

You need to remember the following Trigonometric Identity:

cos\alpha =\frac{adjacent}{hypotenuse}

In this case, you can identify in the figure that:

\alpha =35\°\\adjacent=9\\hypotenuse=x

Then you must substitute these values into cos\alpha =\frac{adjacent}{hypotenuse}:

cos(35\°) =\frac{9}{x}

Finally, you need to solve for "x" in order to find its value. This is:

(x)(cos(35\°))=9\\\\x=\frac{9}{cos(35\°)}\\\\x=10.98

Rounding the result to the nearest tenth, you get:

x\approx11
