when you use a graph to solve a problem about how far a car traveled during a specified time during which it was accelerating how many area calculations do you have to make? what is/ are the shape/shapes you are calculating? a. one area calculation, a rectangle b. one area calculation a triangle c. two area calculations both triangles d. two area calculations a rectangle and a triangle?
To determine how far a car traveled during a specified time while accelerating using a graph, you would need to calculate the area under the curve on the graph. The shape of this area calculation depends on the specific characteristics of the graph.
If the graph represents the velocity of the car over time (i.e., the y-axis represents velocity, and the x-axis represents time), then the area under the curve represents the distance traveled. In this case, you would be calculating the area under a curve.
The shape of the area calculation can vary depending on whether the graph depicts a constant acceleration or if the acceleration is changing.
If the acceleration is constant (making the velocity-time graph a straight line), then the shape of the area calculation would be a rectangle. In this case, you would only need to make one area calculation.
If the acceleration is changing (making the velocity-time graph a curved line), then the shape of the area calculation would consist of both a rectangle and a triangle. The rectangle would represent the distance traveled during the constant acceleration phase, and the triangle would represent the distance traveled during the changing acceleration phase. In this case, you would need to make two area calculations.
So, the answer to your question would be:
c. two area calculations, both triangles, if the acceleration is changing.
or
d. two area calculations, a rectangle, and a triangle, if the acceleration is changing.
or
a. one area calculation, a rectangle, if the acceleration is constant.
