Carl wants to buy a television that costs $500, including taxes. To pay for the television , he will use a payment plan that req
uires him to make a down payment of $125, and then pay $ 72.50 each month for 6 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan? Explain. A) 6% B) 12% C) 58% D) 89%
1 answer:
The original price is $500.
The new price with the payment plan is $560.
The percent change equation is shown in the picture.
First we find the difference or the amount of change.
560-500= 60.
To find the percent we divide 60 (the amount of change) over 500, the original amount.
60/500= 0.12.
0.12 as a percent is 12%
The answer is B. 12%

Answer:
See below.
Step-by-step explanation:
So, we have:
Recall that secant is simply the reciprocal of cosine. So we can:
Now, recall the unit circle. Since cosine is negative, it must be in Quadrants II and/or III. The numerator is the square root of 3. The denominator is 2. The whole thing is negative. Therefore, this means that 150 or 5π/6 is a candidate. Therefore, due to reference angles, 180+30=210 or 7π/6 is also a candidate.
Therefore, the possible values for theta is
5π/6 +2nπ
and
7π/6 + 2nπ
