Answer:
<em>The x-coordinate is changing at 10 cm/s</em>
Step-by-step explanation:
<u>Rate of Change</u>
Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:

We have

Or, equivalently

We need to know the rate of change of x respect to t. We'll use implicit differentiation:

Solving for dx/dt

Plugging in the values x=1, y=3, dy/dt=5

The x-coordinate is changing at 10 cm/s

Look at the 2 graphs. Restaurant A, the median is 35 (inside the box of plot). For Restaurant B, the median is 25 (shown as a line on that plot).
So 35-25=10 and therefore the median number of employees at Restaurant A is 10 more than the median at Restaurant B.
Answer:
1 : 140
Step-by-step explanation:
The scale used to make the model of height 4.2 feet = 1.28016m of a skyscraper (a very tall building) of height 525m is given as:
1.28016/525
= 1 : 410.156
≈ 1 : 410
