The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes: A graph is titled Distance Vs. Time is shown. The x axis is labeled Time in minutes and shows numbers 0, 1, 2, 3, 4, 5. The y axis is labeled Distance from Ocean Surface in meters. A straight line joins the points C at ordered pair 0,66, B at ordered pair 1, 110, A at ordered pair 2, 154, and the ordered pair 3, 198. Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C. (4 points) Part B: What are the initial value and slope of the graph, and what do they represent? (6 points) Source StylesNormal

Step-by-step explanation:The slope of AB and BC are the same.

The initial value is 60 m and the slope is 40 m/min.

Step-by-step explanation:

The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.

See the graph attached.

Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.

Now, those two triangles are similar and hence the slope of line segment AB will be .

Again, the slope of the line segment BC will be

Hence,  and the slope of AB and BC are the same. (Answer)

Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that 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. (Answer)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
