The slope in fraction form is -9/4 so converted to a decimal is -2.25
Answer:
x = 3 or -3
Step-by-step explanation:
So you have the equation x² - 9 = 0
Move the 9 to the other side: x² = 9
Then take the square root of both sides:
= ±
x = ±
= ±3
x = 3 or -3
"Part A: What is the y-intercept of the function, and what does this tell you about the horse? (4 points)" The y-intercept is (0,8), which tells us that at the beginning the horse is 8 miles from the barn.
"Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points)" The value of the function at x=1 is 58 and that at x=3 is 158. Thus, the change in the horse's distance from the barn is 158-58, or 100 feet. The time period involved here is 2 sec. Thus, the average rate of change of the horse's position with respect to time is
100 feet
average rate of change = ---------------- = 50 ft/sec
2 sec
If the horse were to move steadily at a fixed rate from 58 feet to 158 feet from the barn, its average rate would be 50 ft/sec.
"Part C: What would be the domain of the function if the horse continued to walk at this rate until it traveled 508 feet from the barn? (2 points)"
Here time begins at x=0 and ends at x=4 sec. Thus, the appropriate domain here is [0,4] sec.
Answer:
-12x^4y^6z^3
Step-by-step explanation:
The narrator uses the phrase "making trial of everything" from the passage to present Eppie as curious. The correct option is B.
Given a passage which is shown in attached images.
Option B is the best answer. The first paragraph describes Eppie as "a creature of endless dreams and ever-increasing desires", someone who "tried everything to the test". In this context, his "trying everything" can be read as acting on his curiosity by trying to experience the world around him.
Options A, C and D are incorrect because in the context of her "doing everything to check", Eppie could be seen as curious, unfriendly (option A), disobedient ( option C) or criticize (option D).
Hence, the narrator uses the phrase "making trial of everything" from the given passage to present Eppie as curious.
