Answer:
20 miles per hour
Step-by-step explanation:
The distances traveled by each car are perpendicular, so we can find the distance between the cars using the Pythagoras' theorem between their distances traveled:
Where d is the distance between the cars, d1 is the distance traveled by the first car and d2 is the distance traveled by the second car.
The distance traveled is calculated by the speed times the time traveled, so we have:
The rate that the distance is increasing can be found with the derivative of the distance in relation to the time:
So the rate that the distance increases is always 20 miles per hour, and it's independent of the time.
Answer:
48 minutes
Step-by-step explanation:
First, we divide 1.6 by 2 to see how much out of the hour we will walk. This equals 0.8. We have walked for 0.8 of an hour. An hour is 60 minutes. 60 minutes multiplied by 0.8 is 48. It takes 48 minutes to walk 1.6 miles at 2mph.
To find a percentage of a number, convert the percent to a decimal, then multiply the number by it. In this case, 16% = 0.16.
N * 0.16 = 17
N = 106.25

Answer:
slope: 1; y-intercept: 3
Step-by-step explanation:
The y-intercept is the y-value where the graph crosses the vertical y-axis. That value is 3.
The slope is the "rise" divided by the "run" for the graph. Here, the graph goes up 1 unit for each unit to the right, so the slope is ...
m = rise/run = 1/1 = 1
The slope is 1, and the y-intercept is 3.
Answer:
d
Step-by-step explanation:
it should be the one with the greatest power to the lowest power If I remember correctly.
