For questions 9&10 you will just have to graph it on the graph. Hopefully I helped you tho.
Answer:
If Ahmad travel 280 miles the cost of both plans will be the same
Step-by-step explanation:
Let's call x the number of miles traveled by Ahmad.
If we say that C1 is the cost of the first plan and C2 is the cost of the second plan then:
C1 = initial fee + additional cost per mile
C2 = initial fee + additional cost per mile
We want to know for what value of x, cost 1 will be equal to cost 2. Then we equate the equations and solve for x.
Answer:
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)
