Answer:

50

Step-by-step explanation:

If n = 6 the equation becomes 9(6)-4 or 9 x 6 - 4

9 x 6 = 54

54 - 4 = 50

Thus, the answer is 50

If r and p are perpendicular:

1 + 2 = 90°

3 = 90°

4 + 5 = 90°

6 = 90°

If any one of these are true, r and p must be perpendicular

Find the measurement of the inscribed angle CDB indicated below90Your answer:29°24°45°56°
Shtirlitz [24]

It is possible to see that the angle DCB is a right angle. It is also seen that sides CD and CB are congruent. So, the measure of angles CDB and CBD is the same. Since the sum of the three angles must be equal to 180°, the angle CDB must be equal to 45°.

∠CDB + ∠CBD + ∠DCB = 180°

∠CDB + ∠CBD + 90° = 180° (Replacing the value of angle DCB)

∠CDB + ∠CBD = 180° - 90° (Subtracting 90° on both sides of the equation)

∠CDB + ∠CBD = 90° (Subtracting)

2*∠CDB = 90° (Since ∠CDB = ∠CBD )

∠CDB = 90°/2 (Dividing by 2 on both sides of the equation)

∠CDB = 45°

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
