Solve the problem.
Instruments on a satellite measure the amount of power generated by the satellite's power supply. The time t and the power P can be modeled by the function P = 50e^{t/300}, where t is in days and P is in watts.
How much power will be available after 378 days? Round to the nearest hundredth.
a. 141.8 watts
b. 14.18 watts
c. 1.41 watts
d. 0.14 watts

Why not just plug in t = 378 in the expression?

girl : Am I pretty? Boy : NO. Girl : Do you want to be with me forever? Boy : NO. Girl : Would you cry if I walked away?Boy : NO. She heard enough, and was hurt. She walked away, tears ran down her face. The boy grabbed her arm. Boy : Your not pretty, your beautiful. I don't want to be with you forever, I NEED to be with you forever. And I wouldn't cry if you walked away, I would DIE. (Boy whispers) : Please? Stay with me. (Girl whispers) : I will. Tonight at midnight your true love will realize they love you. Something good will happen to you between 14 pm. Tomorrow it could be anywhere. Get ready for the biggest shock of your life! If you don't post this to 5 other pages. You will have relationship problems for the next 10 years

Plugging in t = 378 gives 14.18 watts, option b. If I have understodd the problem, this is correct.

Elekt how can be sure that this the right answer?

Well, if I have understood the problem, it asks how much power it is after 378 days. Since you have a function that describes the amount of power at any instant t, it should just be to plug in t = 378 days when t is in days :)

Hmmz, not even sure what that means because of the \[0 > 50.62\] in there :P

And are you just supposed to list the rational elements of that set?

Elekt Group TitleBest ResponseYou've already chosen the best response.0
Ah, well then the elements of the set will be all the numbers inside there, unless you are looking for just rational numbers. In that case, it will only be 5, 3, 0, 0/5, 0, 62

Question 10 Find the value of the indicated trigonometric function of the angle θ in the figure. Give an exact answer with a rational denominator. dw:1322515842341:dw a. \frac{8 \sqrt{39}}{39} b. \frac{5}{8} c. \frac{5 \sqrt{39}}{39} d. \frac{ \sqrt{39}}{8}

But I guess since some of the elements occur several times, you need just list up the the numbers that occur several times just once.

yes, \[\sin \theta = \frac{5}{8}\] Because sines is defined as the relationship between the opposite side and the hypotenuse.
