Find the equation for the tangent line and type the coordinate for the point of tangency. 11.1 Equation of tangent line: Point of tangency: (no spaces) x = -2 y = -2 x = 2 y = -2 11.1 8. Find the equation for the tangent line and the coordinate for the point of tangency. x = 4 y = 4 Equation of tangent line: Point of tangency: (no spaces) x = 6 y = 6 11.1 9. A satellite orbits 250 miles above the surface of the earth. How far from the observation tower is thesatellite? observation tower note: radius of earth = 4000 miles find this distance Satellite 250 miles above earth surface distance to the nearest mile = 10. The moon is about 221,463 miles from the Earth. When the moon is on the horizon how far away is it? 11.1 note: radius of earth = 4000 miles person moon distance to the nearest mile = 11. P is a point outside the the circle. What is true about segment PA and segment PB? 11.1 A B PA > PB PA = PB PA + PB = 0 PA < PB P 12. PA and PB are tangent to the circle. Find the value of x and the length of PB. 11.1 A B x + 7 2x - 3 PB = x = P 13. PA and PB are tangent to the circle. Find the value of x and the length of PA. 11.1 A B 2x2 - 12 x2 + 13 PA = x = P 11.1 14. BC is tangent to circle A at point B, what do you know is true about m∡ABC?
