To avoid a service fee, your checking account balance must be at least $500 at the end of each month. Your current balance is

seraphim [82]

Answer: At least $91.91

Step-by-step explanation:

From the question, we are informed that to avoid a service fee, the checking account balance must be at least $500 at the end of each month.

Since the current balance is $525.17 and $117.08 has been spent, the balance will now be:

= $525.17 - $117.08

= $408.09

Since the checking account balance must be at least $500 at the end of each month and we currently have $408.09, this means that there will still be a need to add $91.91.

= $500 - $408.09

= $91.91

At least $91.91 must be added to avoid the fee.

Find the derivative of ln(cosx²).

RoseWind [281]

Answer:

$\displaystyle \frac{dy}{dx} = -2x \tan (x^2)$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Derivative Rule [Chain Rule]: $\displaystyle \frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle y = \ln (\cos x^2)$

Step 2: Differentiate

Logarithmic Differentiation [Derivative Rule - Chain Rule]: $\displaystyle y' = \frac{(\cos x^2)'}{\cos x^2}$
Trigonometric Differentiation [Derivative Rule - Chain Rule]: $\displaystyle y' = \frac{-\sin x^2 (x^2)'}{\cos x^2}$
Basic Power Rule: $\displaystyle y' = \frac{-2x \sin x^2}{\cos x^2}$
Rewrite [Trigonometric Identities]: $\displaystyle y' = -2x \tan (x^2)$
