a.
To graph:
The graph of the weight gain and loss during pregnancy and the
Solution:
The graph of the weight gain and loss during pregnancy is as follows:
Explanation:
Given information:
A women’s weight naturally increases during pregnancy. When she delivers, her weight decreases immediately by the weight of the child. Suppose a
Formula used:
(1) Equation of the line passing through two points
Calculation:
Here, the vertical axis represents the weight and the horizontal axis represents the time period.
At time
So, coordinates are
Now to find the slope of the line passing through the coordinates
By using formula for the equation of the line passing through two points, it gives
By simplifying,
By multiplying by
By adding
Thus, the equation of line is
Now find the equation of the line passing through coordinates
By using the formula for the equation of a line passing through two points, it gives
By simplifying,
By multiplying by
By adding
Thus, the equation of the line is
Thus, we get the function for weight gain and loss during pregnancy and the
Therefore, the graph of the weight gain and loss during pregnancy and the

- Coast Guard Patrol Search Mission The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and decided to go in for a closer look. Flying in a straight line at a constant altitude of 1000 ft and at a steady speed of 256 ft/s, the aircraft passed directly over the trawler. How fast (in ft/s) was the aircraft receding from the trawler when it was 1400 ft from the trawler? (Round your answer to one decimal places.) 1000 ft 180 × ft/s Need Help?
