Can someone show me way of solving this​

Mathematics

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}

3x²-4x+7 how do I find the domain?
Eddi Din [679]
The domain of this equation is the lowest x value to the highest x value. For example: lowest is -4 and highest is 3. You would write it as [-4,3]

For this equation, the domain is (-infinity,infinity) because there is no lowest or highest x value.

Answer:

$1.25f + $0.75f

Step-by-step explanation:

The cost of one bagel is $1.25 and cream cheese costs $0.75 per person. The total amount Jack and Jenn will spend on breakfast depends on the number of friends that eat breakfast.

to get the total amount spent on breakfast, multiply the cost of bagel by the number of friends and the cost of cream cheese by the number of friends. Add these numbers

The total amount spent on food = $1.25f + $0.75f

Sauron [17]
1.95 = .21(5) + .06m

1.95 = 1.05 + .06m

Solving (if needed)
Subtract 1.05 from each side
1.95 - 1.05 = .06m
.90 = .06m
Divide .06 on both sides
15 = m
