Answer:
Option 2 - 1 minute
Step-by-step explanation:
Given : Michelle jumps from a plane at an altitude of 1000 m. After 10 seconds her parachute opens. The graph shows the relationship between her altitude and time.
To find : How long does it take for her to be half way between the plane and the ground?
Solution :
Total altitude is 1000 m.
Half of the way between plane and the ground is
Now, Referring the graph given at an altitude of 500 m the line passes at time t=1 min.
Therefore, The time taken to be half way between the plane and the ground is 1 min.
Hence, Option 2 is correct.
Refer the attached figure below.

Answer:
The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.
Step-by-step explanation:
We represent the straight line by using this formula from Analytical Geometry:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
Now we clear the y-intercept:
If we know that ,
and
, the y-intercept of the line is:
The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.
