Answer:
Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
Step-by-step explanation:
Let suppose that Han's younger sister accelerates at constant rate, then, acceleration (), measured in meters per square second, can be calculated by the following equation:
Where:
,
- Initial and final times, measured in seconds.
,
- Initial and final speeds, measured in meters per second.
If we know that ,
,
and
, the acceleration of the younger sister is:
Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
Answer:
Step-by-step explanation:
The slope formula for a straight line is:
Where, 'm' is the slope and 'b' is the y-intercept.
To find the x-intercept of a line, we need to equal 'y' to zero, and then solve for 'x'. In this case we know that the x-intercept is 1, so we have the point (x1, y1)=(1,0). We are given a second point which is: (x0, y0)=(-2, 12).
To find the slope, we use the following formula:
Now, The equation of the line is: y - y0 = m(x-x0). Then, substituting the values of 'm', 'x0' and 'y0' we have that:
The equation of the line using the slope-intercept form is:
