It is estimated that a driver takes, on average, 1.5 seconds from seeing an obstacle to reacting by sound of lightning (thunder) travels at the speed of sound, which is about 750 miles per hour. 1. If you see a flash of lightning, then hear the thunder 4 seconds later, how far away is the lightning? 2. Now let’s generalize that result. Suppose it takes n seconds to hear the thunder after a flash of lightning. How far away is the lightning, in terms of n?

step-by-step explanation:

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
