Ok so, based on the graph lets say that x = seconds and y = depth of dolphin. the interception in both points is when they are at 0 i.e when x is equals 0 and y equals 0. So At 0 seconds, the dolphin is 42 feet below the surface. So we say that x = 0, y = -42 and then the y intercepts = -42 so the point of interception is(0 (seconds),-42(depth of the dolphin)) When the clock says it's 14 seconds, the dolphin is even with the surface (0 below the surface this time). So we say that x = 14, y = 0. In this case The x intercept = 14 (14,0). But we need to calculate The slope with the formula= (y2 - y1)/(x2 - x1) = 42/14 = 3. Therefore, the formula for this line is y = 3x - 42.
The answer is 3 7/21 or 3 1/3 (i don't see the answer choice)
multiplying a number by 1 doesn't change its value so the final answer is still 3 and 1/3.
I did my calculations and i rechecked it by redoing the question and I got "37800".
Answer:
40
Step-by-step explanation:
200 divided by 5 is 40, and 40 times 1 is 40.
A= 1/2 bh
2A/b=h
just solve the original formula in terms of the height
Hope this helps
