Since the shark is in a deep water level of specifically 80 feet it is then represented by a negative coefficient. This is due to the vector quantity the measure represents as decelerating or sinking or downward in direction. As oppose the shark moves upward with a height of 15ft.
Thus the expression will be -80ft + 15 ft = -65ft is the displacement.
15ft is positive since the movement is upward and the displacement then from the origin to the point of last position is 65ft, negative.
Answer:
<h2>True the speed S in in Feet/second</h2>
Step-by-step explanation:
In this problem we are required to solve for the speed of an object.
given that the expression to solve for the speed is expressed as
speed= distance/time
given data
distance=100 feet
time=2.5 seconds
substituting our given data into the expression we can solve for speed as
speed (S)=100/2.5
S= 40feet/seconds
upon substituting our data the speed S was found to be 40feet/s
True the speed S in in Feet/second
Use the law of cosines to solve for angle A. Plug your known side length values into the equation a^2 = b^2 + c^2 – 2bc cos A.
Then use the law of sines to find angle B. (Sin A/a = Sin B/b = Sin C/c).
Because the two red angles within B are congruent, divide your angle measure in half.
From there, do the law of sines to solve for x. Good luck!
