Answer:

Step-by-step explanation:

(x^2-3x+1)^{(2x^2+x-6)}=1\ we \ take \ the \ logarithm\\\\(2x^2+x-6)*ln(x^2-3x+1)=0\\\\(2x^2+x-6)=0\ or\ x^2-3x+1=1\\\\1)\\2x^2+x-6=0\\2x^2+4x-3x-6=0\\2x(x+2)-3(x+2)=0\\(x+2)(2x-3)\\x=-2\ or\ x=\dfrac{3}{2} \\\\2)\\x^2-3x=0\\x(x-3)=0\\x=0\ or\ x=3\\\\sol=\{-2,0,\dfrac{3}{2},3\}\\

What is the domain of the function y=-720t + 3600 ?
Colt1911 [192]

Answer:

We conclude that:

\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:

Please also check the attached graph.

Step-by-step explanation:

Given

Given the function

y=-720t\:+\:3600

To determine

What is the domain of the function y=-720t + 3600

We know that the domain of the function is the set of input argument values for which the function is real and defined.

Given the function

y=-720t\:+\:3600

From the given function, it is clear that the function has no undefined points nor domain constraints.

Therefore, the domain of the function is

-\infty \:

Thus, we conclude that:

\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:

Please also check the attached graph.

Simplify (square root 2)( square root of 2^3)
steposvetlana [31]

Answer:

\large\boxed{(\sqrt2)(\sqrt{2^3})=4}

Step-by-step explanation:

(\sqrt2)(\sqrt{2^3})\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\sqrt{2\cdot2^3}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\sqrt{2^{1+3}}=\sqrt{2^4}\\\\(1)=\sqrt{2^{2\cdot2}}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=\sqrt{(2^2)^2}\qquad\text{use}\ \sqrt{a^2}=a\ \text{for}\ a\geq0\\\\=2^2=4\\\\(2)=\sqrt{2\cdot2\cdot2\cdot2}=\sqrt{16}=6\ \text{because}\ 4^2=16

64.24  = 4x \\  \frac{64.24}{4}  =  \frac{4x}{4}  \\ 16.06 = x

so one book is $16.06
