Answer: -6, -8/7, 7/8, 7.5

Step-by-step explanation: To compare them, you need to make sure they are all either fractions or decimals. -6 = -6 .... -8/7 = -1 1/7 ...... 7/8 = 7/8 ..... and 7.5 = 7 1/2

-6, -1 1/7, 7/8, and 7 1/2

A particle moves along the curve below. y = √ 8 + x 3 As it reaches the point ( 1 , 3 ) , the y -coordinate is increasing at a r
Dmitry [639]

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:

\displaystyle \frac{dy}{dt}=\frac{dy}{dx}\cdot \frac{dx}{dt}

We have

y=\sqrt{8+x^3}

Or, equivalently

y^2=8+x^3

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

\displaystyle 2y\cdot \frac{dy}{dt}=3x^2\cdot \frac{dx}{dt}

Solving for dx/dt

\displaystyle \frac{dx}{dt}=\frac{2y\cdot \frac{dy}{dt}}{3x^2}

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

\displaystyle \frac{dx}{dt}=\frac{2(3)\cdot 5}{3\cdot 1^2}=10

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.
