I don’t understand this problem help me to solve step by step and give answer in exponential format and 3 significant figures Example: 5.23e4
If you have spent much time driving, you probably have a good sense of speeds between about 10 and 70 miles per hour. But what are these in meters per second? What do we mean when we say that something is moving at 10 m/s? To get a better sense of what these values really mean, do some observations and calculations on your own: • calculate typical car speeds in meters per second • estimate jogging and walking speed by timing yourself; convert the measurements into both m/s and mi/h • determine the speed of an ant, snail, or falling leaf
Meanwhile at the ballpark Juan was practicing his hitting while talking to some friends. He started telling them how he hit the ball over the 50 foot light tower yesterday.
The formula for this hit is , h(x)=-16x^2+60x+4, where h is the height of the ball and x is the number of seconds the ball is in the air.
1. How can Juan provide proof to the friends that he actually hit the ball over the tower?
2. How high did Juan actually hit the ball? Is Juan able to mathematically back up how high he says he hit the ball?

Think about the average number of breaths that a person takes in 1 min. This number varies depending on whether the person is exercising, sleeping, angry, serene, and so forth. To the nearest order of magnitude, we shall choose 10 breaths per minute as our estimate. (This estimate is certainly closer to the true average value than an estimate of 1 breath per minute or 100 breaths per minute.) b) What if the average lifetime were estimated as 80 years instead of 70? ?Would that change our final estimatearrow_forward
