Answer:
3y+3\8
Step-by-step explanation:
The answer is 471 feet.
If A = man to left of balloon
<span>B = balloon </span>
<span>C = man to right of balloon </span>
<span>∠BAC = 75°20' </span>
<span>∠BCA = 49°30' </span>
<span>∠ABC = 180 - 75°20' - 49°30' = 55°10' </span>
<span>AB = 400 ft </span>
<span>Now we have to find the value of x, which is the side opposite to angle of 75°20' </span>
<span>Using Law of Sines: </span>
<span>x/sin(75°20') = 400/sin(55°10') </span>
<span>x = 400 * sin(75°20') / sin(55°10') </span>
<span>x = 471.44 </span>
<span>x = 471 ft </span>
Answer:
s = 500 + .12(r - 1000)
Step-by-step explanation:
Answer:
3x³ + 2y
Step-by-step explanation:
We use sum of squares to factor out the expression:
(3x³ + 2y)²
In that case, we look for the answer choice with 3x³ + 2y as a factor. We should get the 3rd Choice as our answer.
