Find the length of the curve, l. y = ln(cos x), 0 ≤ x ≤ ď€/4

Length of curve, L=0.3828

Step-by-step explanation:

We are given a curve

Length of arc L=

Where,

Derivative of y

Substitute y' into ds

Thus, Length of curve, L=0.3828

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
