solution:
x˄2 = a ⇒ x = ±√a
The difference between the solutions is
√a - (-√a) = 2√a = 30 ⇒ √a = 15
Therefore,
a = 225.
Answer:
Jupiter to Sun = 7.688 * 10⁸km
Step-by-step explanation:
Given
Earth to Moon = 3.844 * 10⁵km
Jupiter to Sun = 2 * 10³ times Earth to Moon
Required
Determine the average distance from Earth to Moon
Jupiter to Sun = 2 * 10³ times Earth to Moon
Substitute 3.844 * 10⁵km for Earth to Moon
Jupiter to Sun = 2 * 10³ * 3.844 * 10⁵km
Collect Like Terms
Jupiter to Sun = 2 * 3.844 * 10³ * 10⁵km
Jupiter to Sun = 7.688 * 10³ * 10⁵km
Jupiter to Sun = 7.688 * 10⁸km
<em>Hence, option C answers the question</em>
Top triangle: if the know angle measures are 90 and 55 and there are a total of 180, 90 + 55 + a = 180. This means that angle a = 35°
Bottom triangle: if a is 35, the angle connected to it is 35 because they are vertical angles. The angles of this triangle are 35 + 120 + b = 180. Angle b = 25°
