Differentiating Functions of Other Bases In Exercise, find the derivative of the function.

Mathematics
1 answer:
zimovet [89]3 years ago
6 0

Answer:

y' = -\frac{1}{2.3x}

Step-by-step explanation:

The derivative of a*x^{n} is a*n*x^{n-1}. The derivative of 3x^{-1} is -3x^{-2}, for example.

Derivative of the log function:

y = \log_{a}{f(x)}

Has the following derivative

y' = \frac{f'(x)}{\ln{a}*f(x)}

In this problem, we have that:

y = \log_{10}{\frac{3}{x}}

So

a = 10, f(x) = \frac{3}{x} = 3x^{-1}, f'(x) = -3x^{-2}

The derivative of the function is:

y' = \frac{f'(x)}{\ln{a}*f(x)}

y' = \frac{-3x^{-2}}{2.3*3x^{-1}}

y' = -\frac{1}{2.3x}

I thought of the number that is between 104 and 140. The number is divisible by 6 and 15. What is my number?
Katena32 [7]

Answer:

120

Step-by-step explanation:

Lets find the numbers multiples of 6 that are in the range from 104-140:

108, 114, 120, 126, 132, 138

Now out of these lets find which is divisible by 15

\frac{108}{15}=7.2\\\\\frac{114}{15}=7.6\\\\\frac{120}{15}=8\\\\\frac{126}{15}=8.4\\\\\frac{132}{15}=8.8\\\\\frac{138}{15}=9.2

120 Is the only solution in this set which is also equally divisible by 15, making it the answer.

Find the value of 7 Y if 3 bracket Y - 1 bracket is equal 21​
lawyer [7]

Answer:

7y = 56

Step-by-step explanation:

3(y - 1) = 21

Divide 3 on both sides:

y - 1 = 7

Add 1 to both sides:

y = 8

Multiply by 7 on both sides:

7y = 56
