<h3>Answer:</h3>
6.8 inches
<h3>Explanation:</h3>The shortest distance from P to the circle is along the line between P and the center of the circle. That line is the hypotenuse of the right triangle whose legs are PQ and QC (where C is the circle center).
The Pythagorean theorem tells you
... PC² = PQ² +QC²
... PC² = 13² +9² = 250
... PC = √250 = 5√10 ≈ 15.8114 . . . . inches
The distance from P to the circle is 9 in less than this, so is
... 15.8114 - 9 = 6.8114 ≈ 6.8 . . . . inches
Answer:
x = ± 2
Step-by-step explanation:
Given
16 - 2x² = - 64 ( subtract 16 from both sides )
- 2x² = - 80 ( divide both sides by - 2 )
x² = 40 ( take the square root of both sides )
x = ± = ±
= ± 2
