Answer:
A. If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points
B. From the graph, it is clear that the initial value of the graph is 60 m and it represents the initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.
The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min.
Step-by-step explanation:
Answer:
y = 
x -4
Step-by-step explanation:
The slope-intercept form of an equation of a line is given by:
y = mx + b, where m = slope and b = y-intercept
Given the slope and point on a line, you can solve for 'b' in the equation:
(3, 3) - x = 3, y = 3
slope =
Plug into the equation:
3 = *3 + b
3 = 7 + b
-4 = b
y = x - 4
Mark could travel 682.5 miles in 7.5 hours.
To solve this you have to find how fast he travels per hour.
455 miles/5 hours=91 mph
91 mph multiplied by 7.5 hours(91 x 7.5)= 682.5
682.5 Miles in 7.5 hours
Hope this helped you! :D
