Sally's balance on her credit card is $75.00 on the first day of august. she makes a payment of $18.00 on august 17 and

Travka [436]

The average daily balance for the month was $84.21, and the finance charge for the month was $30.13.

<h3><u>Averages</u></h3>

Given that Sally's balance on her credit card is $75.00 on the first day of August, and she makes a payment of $18.00 on August 17 and a new purchase of $41.00 on August 29, and the annual interest rate is 21.25%, to determine what is Sally's average daily balance and finance charge for the month of August, the following calculation must be made:

75 x ((21.15/12 x 16) / 100) + 75 = A = 86.89
57 x ((21.15/12 x 13) / 100) + 57 = B = 70.06
98 x ((21.15/12 x 3) / 100) + 98 = C = 103.18
(86.89 x 16 + 70.06 x 13 + 103.18 x 3) / 31 = X
84.21 = X
86.89 + 70.06 + 103.18 - 75 - 57 - 98 = Y
30.13 = Y

Therefore, the average daily balance for the month was $84.21, and the finance charge for the month was $30.13.

Solve the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to two decimal places

Montano1993 [528]

The solution of the given equation is :

cosθ = 1/2 when θ = π/3 + 2kπ or 5π/3 + 2kπ

cosθ = -1 when θ = π + 2kπ

Since cos2θ + sin2θ = 1, sin2θ = 1 - cos2θ

So, the given equation is equivalent to 2(1 - cos2θ) - cosθ = 1

-2cos2θ - cosθ + 1 = 0

2cos2θ + cosθ - 1 = 0 (multiplying the entire equation by -1)

(2cosθ - 1)(cosθ + 1) = 0 (taking common)

cosθ = 1/2 or cosθ = -1 (on equating it to zero)

cosθ = 1/2 when θ = π/3 + 2kπ or 5π/3 + 2kπ

cosθ = -1 when θ = π + 2kπ
