Answer:

B.) No, because it fails the vertical line test.

Step-by-step explanation:

You can determine whether or not graphs represent functions by performing the vertical line test. This test states that to be a function, there must only be one output for every input. In other words, there must be only one "y" value per "x" value. As you can see, for some "x" values there is more than one "y" value.

The easiest way to perform this test is by placing your finger at the top of the graph and moving it downwards. If you cross the line twice, then it must not be a function.

A circular grade has a circumference of 38 yards .Lars is digging a straight line along the diameter of the garden at a rate of
Alborosie

Answer:

It will take 4 hours to dig access to the garden.

Step-by-step explanation:

Given that a circular grade has a circumference of 38 yards, and Lars is digging a straight line along the diameter of the garden at a rate of 3 yards, to determine how many hours it will take to dig access to the garden, the following calculation, knowing that the diameter of a circle is equal to the circumference divided by π:

38 / π = X

38 / 3.14 = X

12.09 = X

12.09 / 3 = 4.03

Therefore, it will take 4 hours to dig access to the garden.

After the advance-purchase deadline passes, the cost of attending a particular event is $99, which is 10% more than before. What
Harman [31]

The advance purchase price is $90.

Step-by-step explanation:

Ticket price after deadline = $99

Let,

x represents the advance-purchase price.

Suppose that the advance purchase price is 100%.

As 10% increases, the amount becomes;

(100+10)% = 110%

The amount after deadline is 110% of advance purchase price.

110% of x = 99

\frac{110}{100}*x=99\\1.1x=99

Dividing both sides by 1.1

\frac{1.1x}{1.1}=\frac{99}{1.1}\\x=90

The advance purchase price is $90.

Can someone show me way of solving this​
erma4kov [3.2K]

Step-by-step explanation:

f(x) =  ln( \frac{1}{x} )

To find the derivative, notice we have a function 1/x inside of another function, ln(x)

We use what we call the chain rule,

It states that

derivative of a '

\frac{d}{dx} f(g(x)) =  f '(g(x)) \times \: g '(x)

Here f is ln(x)

f is 1/x

So first, we know that

\frac{d}{dx} ( ln(x)  =  \frac{1}{x}

so

f'(g(x)) =  \frac{1}{ \frac{1}{x} }

We know that

g'(x) =  - \frac{1}{ {x}^{2} }

So we have

x \times  -  \frac{1}{ {x}^{2} }  =   \frac{ - 1}{x}
