-8
the rate of change is -2 and the difference in y from 4 to 8 is 4 so 4 * -2
Answer: The objects instantaneous velocity at that point
Step-by-step explanation:
On a position versus time graph, the displacement is the vertical difference between two points and the time interval is the horizontal difference.
The ratio of displacement to time interval is the the objects instantaneous velocity at that point. This ratio is also the slope of the line.
Hence, The slope at a point on a position versus time graph of an object is the objects instantaneous velocity at that point.
Answer:
1 1/3
Step-by-step explanation:
Answer:
B. 10
Step-by-step explanation:
First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)
Let's first label the leg of the second triangle as y.
Then, we can set up this equation
Cross multiplying gives us
84=y^2
So, y=sqrt(84) or 2 sqrt(21).
Now, using the pythagorean theorem, we get
4^2+2sqrt(21)^2=x^2
100=x^2
x=10
Step-by-step explanation:
you simply have to mark the points in which the x and y coordinates are given take for example "1,4" it took him 4 minutes to read 1 page right? the one is marked as X and the 4 is marked as Y so put a point in which the 1 at X and the 4 at Y meet in the coordinates system. Do so with every coordinates and then draw a line in the direction of all the points
