LetF(x, y) be the statement "xcan fooly," where the domain consists of all people ofthe world. Use quantifiers to express each o

Sindrei [870]

Answer:

See steps below

Step-by-step explanation:

Let F(x, y) and W be

F(x,y) = “x can fool y”

W the set of all the people in the world

a) Everybody can fool Fred.

$\forall x \in W,F(x, Fred)$

b) Evelyn can fool everybody.

$\forall y\in W, F(Evelyn, y)$

c) Everybody can fool somebody.

$\forall x \in W,\exists y :F(x,y)$

d) There is no one who can fool everybody.

$\nexists x \in W: \forall y ,F(x,y)$

e) No one can fool both Fred and Jennifer.

$\nexists x \in W: F(x,Fred)\wedge F(x,Jennifer)$

f) Nancy can fool exactly two people.

$\exists x,y \in W:\forall z\neq x,z\neq y, F(Nancy,x)\wedge F(Nancy,y)\wedge (\neg F(Nancy,z))$

A spherical balloon is inflated with gas at the rate of 500 cubic centimeters per minute. How fast is the radius of the balloon

zmey [24]

Using implicit differentiation, it is found that the radius is increasing at a rate of 0.0081 cm per minute.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given by:

$V = \frac{4\pi r^3}{3}$

Applying implicit differentiation, the rate of change is given by:

$\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}$

In this problem, we have that:

$\frac{dV}{dt} = 500, r = 70$

Hence the rate of change of the radius is given as follows:

$\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}$

$19600\pi\frac{dr}{dt} = 500$

$\frac{dr}{dt} = \frac{500}{19600\pi}$

$\frac{dr}{dt} = 0.0081$

The radius is increasing at a rate of 0.0081 cm per minute.
