Answer:

x≅3.57m

Step-by-step explanation:

Kami menerapkan teorema kaki

$a^{2}+b^{2}=c^{2}\\ mengganti\\x^{2}+(3.5)^{2}=5^{2}\\x^{2}=5^{2}-(3.5)^{2}\\x^{2}=25-12.25\\x=\sqrt{25-12.25}=3.57m$

What is the asymptote for the graph of this logarithmic function?<br><br> f(x) = log3(x – 1)

Pepsi [2]

Answer:

Vertical Asymptote:

$x=1$

Horizontal asymptote:

it does not exist

Step-by-step explanation:

we are given

$f(x)=log_3(x-1)$

Vertical asymptote:

we know that vertical asymptotes are values of x where f(x) becomes +inf or -inf

we know that any log becomes -inf when value inside log is zero

so, we can set value inside log to zero

and then we can solve for x

$x-1=0$

we get

$x=1$

Horizontal asymptote:

we know that

horizontal asymptote is a value of y when x is +inf or -inf

For finding horizontal asymptote , we find lim x-->inf or -inf

$\lim_{x \to \infty} f(x)= \lim_{x \to \infty}log_3(x-1)$

$\lim_{x \to \infty} f(x)=log_3(\infty-1)$

$\lim_{x \to \infty} f(x)=undefined$

so, it does not exist

Write the complex number in polar form with argument between 0 and 2.

pychu [463]

<em>Lets say that √(3+i) is the magnitude of your vector. In polar form, i represents the x component and j represents the y component of the vector. Therefore, the polar form is icosθ√(3+i) + jsinθ√(3+i)</em>

draw a diagram :

<em>z = r(cos θ + i sin θ), where z = complex number, r = modulus, θ = angle of rotation For the given:r = 2θ = π/6 √3 + i = 2(cos π/6 + i sin π/6)</em>

the graph F(x) shown below resembles the graph of g(x) = |x| but it has been flipped over the x axis which of the following is t

Radda [10]

Answer:

f(x)=-|x|

Step-by-step explanation:

We have been given a graph of f(x) which resembles with the graph of function g(x) where g(x)=|x|.

It says that graph is flipped over the x-axis.

Now we have to find about which of the following choice correctly describes the given graph.

We know that |x| means absolute value of x so that means g(x)=|x| is absolute function in shape of V.

We know that flipping over x-axis can be done by changing f(x) into -f(x).

<u>Hence correct answer is choice D) F(x)=-|x|</u>
