Answer:

No

Step-by-step explanation:

y^2 = x^2 + 5​

Rewriting

y^2 - x^2 = 5

This is a hyperbola

We can use the vertical line test to show that it is not a function since a vertical line passes through more than one point.

Natali5045456 [20]

Answer:

According to the information of the problem  x = 15 , p=2.90 and dp/dt = -1.15

then   \frac{dx}{dt} = -3.357\\

Step-by-step explanation:

Since everything is changing with respect to time and p,x are related according to the following equation

5p+5x+3px = 71

We need to find the implicit derivative with respect to the time. And we get the following.

5\frac{dp}{dt}+5\frac{dx}{dt}+3x\frac{dp}{dt}+3p\frac{dx}{dt} = 0

\frac{dx}{dt} is what we don't know, so we solve for it and get

\frac{dx}{dt} = - (5\frac{dp}{dt}-3x\frac{dp}{dt})/  (5+3p)

Now. According to the information of the problem  x = 15 , p=2.90 and dp/dt = -1.15

then   \frac{dx}{dt} = -3.357\\
