The derivative of the function is 2x/(3+x²).

<h3>What is Derivative?</h3>

The derivative is the instantaneous rate of change of a function with respect to one of its variables.

Given function:

y= ln(3+x²)

Differentiating and applying chain rule

=1/(3+x²) d/dx(3+x²)

=1/(3+x²) (2x)

= 2x/(3+x²)

Hence, the derivative of the function is 2x/(3+x²).

Answer:

75 cheeseburgers and 86 french fries

Step-by-step explanation:

This is a guessing math problem so do a random amount and change amount of items to get closer to the answer

81 x 3 = $243

80 x 1.50 = $120

243 + 120 = 363 -354 = 9 dollars

we need nine less dollars so 9/1.5 = 6 so six more fries

86 x 1.5 = 129

75 x 3 = 225

129 + 225 = $354

Ms. Lui earned an annual income of 775,000, what is the weekly salary?
jok3333 [9.3K]

Answer:

$14,903.85

Step-by-step explanation:

So, Ms. Lui earns $775,000 each year. To find the weekly salary, we have to divide the annual income by the amount of weeks in a year. There are about 52 weeks in one year. Let's find the weekly salary:

\frac{775000}{52} = 14,903.85

Therefore, Ms. Lui earns $14,903.85 a week.

Hope this helps! If you have questions about my work, please leave them in the comments!
