How you do this is using the formula speed = distance/time. So this is 100/5 which is 20 meters a second. Using the conversion factor (can google "20 meters per second is how many mile") 20 meters a second = 44.7 miles per hour.
In conclusion, the answer you're looking for is D. 44.7 miles per hour.
Answer: -3
Explanation: In this problem, we're given the function f(x) = 2x + 1 and we're asked to find f(-2).
To find f(-2) or the value of the function or the value of the function when <em>x = -2</em>, we simply substitute -2 in for <em>x</em> in our function.
So we have f(-2) = 2(-2) + 1 or -4 + 1 which equals -3.
So f(-2) or the value of the function when x = -3 is -3.
Based on the data shown by the scatterplot on the distances in the solar system, a. an exponential model is appropriate because the scatterplot relating distance to temperature is curved.
<h3>Why is an exponential model appropriate?</h3>
The usage of the natural log to transform some of the variables resulted in the scatterplot of temperature v. distance ratio being curved.
As a result, a linear model cannot be used. The best model will therefore be an exponential model which is best for curves in a scatterplot.

Answer:
15 is 1/4 of 60, and 1/4 is 25%. So, 15 is 25% of 60.
