Answer:

\dfrac{x^{12}}{64}

Step-by-step explanation:

Given: (4x^{-4})^{-3}

We need to simplify it

Here we have exponent of exponent

Exponent law:

(a^m)^n=a^{mn}

a^{-m}=\dfrac{1}{a^m}

First we distribute the exponent -3 with each term inside the bracket.

\Rightarrow (4x^{-4})^{-3}

\Rightarrow 4^{-3}(x^{-4})^{-3}

\Rightarrow 64^{-1}x^{-4\cdot -3}

\Rightarrow 64^{-1}x^{12}

\Rightarrow \dfrac{x^{12}}{64}

Hence, The simplified expression is \Rightarrow \dfrac{x^{12}}{64}

How many x-intercepts would the function shown below have?<br> f(x) = -5x (2x + 1)? (x² – 6)(x² + 9)
BabaBlast [244]

Step-by-step explanation:

Here we have

f

(

x

)

=

2

x

2

(

x

2

−

9

)

, which can be factorized as

f

(

x

)

=

2

x

2

(

x

+

3

)

(

x

−

3

)

As there is no common factor between numerator and denominator, there s no hole.

Further vertical asymptotes are

x

=

−

3

and

x

=

3

and as

f

(

x

)

=

2

x

2

(

x

)

=

−

x

2

, as

x

→

∞

,

f

(

x

)

→

2

, hence horizontal asymptote is

y

=

2

.

Observe that

f

(

−

x

)

=

f

(

x

)

and hence graph is symmetric w.r.t.

y

-axis. Further as

x

=

0

,

f

(

x

)

=

0

. Using calculas we can find that at

(

0

,

0

)

there is a local maxima as

d

y

d

x

=

−

x

(

x

2

−

9

)

2

and at

x

=

0

it is

0

. Further while for

x

<

−

3

and

x

>

3

, function is positive, for

−

3

<

x

<

3

function is negative.

Now take a few values of

x

say

{

−

,

−

,

−

,

−

2

,

−

1

,

,

,

,

,

}

and corresponding values of

f

(

are

Suppose that telephone calls arriving at a switchboard follow a Poisson process with an average of 5 calls per minute. What is t
postnew [5]

Answer:

The correct answer is "0.0842".

Step-by-step explanation:

Given:

X = 5

By using the Poisson's distribution formula, we get

The probability will be:

⇒ P(x=2)=\frac{\lambda^x.e^{-\lambda}}{x!}

By substituting values, we get

                   =\frac{(5)^2\times e^{-5}}{2!}

                   =\frac{25\times e^{-5}}{2!}

                   =0.0842

Graph the system of equations on a graph paper.
inysia [295]

Answer:

Step-by-step explanation:

8x + 6y = 48.....reduces to 4x + 3y = 24

2x - 3y = -6

4x + 3y = 24

-------------------add

6x = 18

x = 18/6

x = 3

2x - 3y = -6

2(3) - 3y = -6

6 - 3y = -6

-3y = -6 - 6

-3y = -12

y = -12/-3

y = 4

solution is : (3,4)

the ordered pair (3,4) lies in quadrant I

the x coordinate of the solution is 3

the y coordinate of the solution is 4
