Use the rational zero thereom to list all possible zeroes of the function f(x)= 5x^8-2x^5-7
Scrat [10]

Possible rational zeros are:

\pm1,\pm7,\pm\frac{1}{5},\pm\frac{7}{5}

Step-by-step explanation:

We need to list all possible zeroes of the function f(x)= 5x^8-2x^5-7 using rational zero theorem.

The rational zero theorem.

rational zero theorem states that zeros can be found by dividing the factors of constant term called p by the factors of the leading co-efficient called q i.e

p/q

In our given function  f(x)= 5x^8-2x^5-7

p = 7

q = 5

Factors of p (7) = ±1, ±7

Factors of q (5) = ±1, ±5

\frac{p}{q} =\frac{\pm1,\pm7}{\pm1,\pm5}

So, possible rational zeros are:

\pm1,\pm7,\pm\frac{1}{5},\pm\frac{7}{5}

Keywords: rational zero theorem, possible zeroes

In a fractional-reserve banking system with no excess reserves and no currency holdings, if the central bank buys $100 million w
loris [4]

Answer:

reserves increase by $100 million and the money supply increases by more than $100 million.

Step-by-step explanation:

Consider the provided information.

It is given that central bank buys $100 million worth of bonds, that means an amount of $100 million in the deposits account of the account holders.

Therefore the reserves increase by $100 million.

It is also given that there are no excess reserves, it means banks can lend the reserves and that will increase the money supply by more than $100 million.

Hence, reserves increase by $100 million and the money supply increases by more than $100 million.

Solve for x.
astra-53 [7]

Answer:

Option: C is correct.

x=\ln\sqrt{\dfrac{t+1}{1-t}}

Step-by-step explanation:

We are asked to solve for 'x' such that we are given a equation as:

\dfrac{e^x-e^{-x}}{e^x+e^{-x}}=t

This equation could also be written as:

e^x-e^{-x}=t(e^x+e^{-x})\\\\e^x-e^{-x}=te^x+te^{-x}\\\\e^x-te^x=te^{-x}+e^{-x}\\\\(1-t)e^x=(t+1)e^{-x}\\\\e^{2x}=\dfrac{t+1}{1-t}

on taking logarithmic function on both the sides we have:

2x=\ln (\dfrac{t+1}{1-t})

(since \ln (e^x)=x )

x=\dfrac{1}{2}\times \ln (\dfrac{t+1}{1-t})  

as we know \dfrac{1}{2}\times \ln b = \ln (b^\frac{1}{2})

Hence, we have: x=\ln\sqrt{\dfrac{t+1}{1-t}}

Hence, option C is correct.
