Matching In Exercises 1-6, match the equation with its graph. [The graphs are labeled (a), (b), (c), (d), (e), and (f).]

If the equation
Answer to Problem 1RE
Solution:
The equation
Explanation of Solution
Given:
The options are:
Explanation:
Here,
Now, in order to find whether the ellipse is horizontal or vertical, represent the equation in the standard form of an ellipse.
The given equation is:
Divide the equation by
Rearrange it in standard form as:
So,
Which is the standard equation for an ellipse, whose major axis is vertical. That is the center of ellipse is
Thus, the correct graph matches for the equation that holds the above properties is option (e).

- Rylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lb a. The resultant force is (Tip: omit degree notations from your answers; e.g. enter cos(45) instead of cos(45°)) b. It's magnitude is lb. c.
