Answer:
Step-by-step explanation:
slope = 
= 
= 
Therefore slope = -7/4
The answer is 1.464 x 10^8
Answer:
70°
Step-by-step explanation:
Connect the center of the circle with endpoints of the chord. Let the center of the circle be point O and endpoints of the chord be points A (let point A lie on the tangent line too)and B.
From the figure, central angle AOB has the measure of 220°.
Consider triangle AOB. This triangle is isosceles triangle because OA and OB are both radii. In this triangle the measure of angle AOB is 360° - 220° = 140°.
Angles OAB and OBA are angles adjacent to the base AB, so they are congruent. The sum of the measures of all interior angles in triangle is always 180°, so
m∠OAB + m∠OBA + m∠AOB = 180°
m∠OAB = m∠OBA = 1/2 (180° - 140°)
m∠OAB = 20°
Since drawn line is tangent line, then OA is perpendicular to this tangent line and
x° = 90° - 20°
x° = 70°

Step-by-step explanation:
I’m pretty sure it’s talking about the amount of water regulated to food for example how much water does gelatin have 90% why? How? Because the food produces its self with water making it absorbed and the best way the question is asking is how many __in units.
