Answer:
Sin O =
Cos O =
Cot O =
Csc O =
Sec O =
Step-by-step explanation:
Do you know the definitions of all the trig functions? If not, you need to memorize them. Also, you need to memorize which functions are positive in each quadrant. All functions are positive in quad I, sine and reciprocal are positive in quad II, tan and reciprocal are positive in quad III, and cos and reciprocal are positive in quad IV. OK?
Tan of an angle is opposite side/adjacent side of a right triangle
If the tan O = - 2. let the opp. side = 2 and adjacent side = 1. Then the hypotenuse =
Sine is positve and equals opp/hyp =
Cos is negative and equals adj/hyp =
Cot is negative and is the reciprocal of the tan or adj/opp =
Csc is positive and is the reciprocal of the sine or hyp/opp =
Sec is negative and is the reciprocal of the cos or hyp/adj =
Answer:
Since the total amount you have to pay for the purchase on the credit card A is lower, then it's the best option.
Step-by-step explanation:
For credit card A the ammount will only be compounded after 1 year, so the total time elapsed for the laon is 1.5 years, while for the credit card B it'll be the full 2.5 years. To compute the total amount of a interest compounded continuously we must apply the formula:
M = C*e^(r*t)
Where M is the total amount, C is the initial amount, r is the interest rate and t is the time elapsed.
For credit card A:
M = 500*e^(0.008*1.5) = 506.03614
For credit card B:
M = 500*e^(0.007*2.5) = 508.8270
Since the total amount you have to pay for the purchase on the credit card A is lower, then it's the best option.

Answer:
1% of 26 is $0.26 so 6% of $26 is $1.56
Step-by-step explanation
The answer for this is very easy all you have to do is for the first half you take 1% and turn it into a decimal which is 0.01 then you multiply 0.01 by 26 which is 0.26. For the next half of the problem, it's just like the last one you take 6% and turn it into a decimal which is 0.06 then you multiply 0.06 by 26 which is 1.56 and then you have your answer.
