Step-by-step explanation:
A fisherman travels downstream at full speed to his favorite fishing spot.
<span>The stream is running at a rate of 5 miles per hour, and he takes an hour to get to the fishing hole. </span>
<span>He catches 5 fish and calls it a day. </span>
<span>He takes twice as long at full speed to get back to the dock going against the current. </span>
<span>(x + 5)/(x - 5) = 2 </span>
<span>x = 15
</span><span>The full speed of the fishing boat is 15 miles per hour.</span>
Answer:
19/100 which is already simplified( it can't be simplified)
How I got the answer: subtract 81 from 100 and you'll get 19.
Put 19 over 100 (19/100) and there's the answer.
square tan theta
(tan^2) + 1 = sec^2
so sec^2 = 11/4
sec = - (sqrt 11)/2
cos= - 2/ (sqrt 11)
answer choice a if you simplify
