Given that f(a+b)= f(a) + f(b) and f(x) is always positive, what os the value of f(0)?
FrozenT [24]
This is a strange question, and f(x) may not even exist. Why do I say that? Well..

[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).

[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!

Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.

To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.

Hello there,

So. . .The word reciprocal mean's the opposite. So we are going to flip the expression all around.So the reciprocal of  \frac{-8b}{5b-6}  is the following:

\frac{5b-6}{-8b}

Hope this helps.

What is the volume of this cylinder?
katrin [286]

Answer:

678.24 in³

Step-by-step explanation:

radius r = 6 in

height h = 6 in

volume V = 678.24 in³

lateral surface area L = 226.08 in²

top surface area T = 113.04 in²

base surface area B = 113.04 in²

total surface area A = 452.16 in²

In Terms of Pi π

volume V = 216 π in³

lateral surface area L = 72 π in²

top surface area T = 36 π in²

base surface area B = 36 π in²

total surface area A = 144 π in²

Agenda: r = radius

h = height

V = volume

L = lateral surface area

T = top surface area

B = base surface area

A = total surface area

π = pi = 3.1415926535898

√ = square root

Calculate volume of a cylinder:

V = πr²h

An investment of $450 increases at a rate of 6.5% per year. What is the growth factor, b?
Alina [70]
\bf \qquad \textit{Amount for Exponential Growth}
\\\\
A=P(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &450\\
r=rate\to 6.5\%\to \frac{6.5}{100}\to &0.065\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
A=450(1+0.065)^t\implies A=450(\stackrel{growth~factor}{1.065})^t
