The answer I’m pretty sure will be -4. (-4+12-36)/7 = -28/7.
Answer:
Height of shuttle at that instant = 1.17 miles
Step-by-step explanation:
Refer the given figure.
C is the position of rocket and B is the position of observer.
Here we need to find AC, that is the height of shuttle at that instant.
Using trigonometric rules on ΔABC, we have
Height of shuttle at that instant = AC = 1.17 miles
Answer:
98.5 degrees.
Step-by-step explanation:
Add up these four numbers and divide by the number of temperatures given. There are four given temperatures. It all adds up to 394. When division occurs, you get 98.5 degrees which would be your answer.
Above statement can be represented as :
Answer:
63/65
Step-by-step explanation:
Recall that sin(a-b) = sin(a)cos(b) - cos(a)sin(b)
Therefore, we have:
sin(a-b) = sin(a)cos(b) - (-3/5)(5/13)
sin(a-b) = sin(a)cos(b) + 3/13
Since sin(x) = opposite/hypotenuse and cos(x) = adjacent/hypotenuse, then if cos(a) = -3/5, sin(a) = 4/5. Likewise, if sin(b) = 5/13, then cos(b) = 12/13.
Therefore, sin(a-b) = (4/5)(12/13) + 3/13 = 48/65 + 3/13 = 48/65 + 15/65 = 63/65
