Answer:
- (a) no
- (b) yes
- (c) no
- (d) no
Step-by-step explanation:
"Of the order x^2" means the dominant behavior matches that of x^2 as x gets large. For polynomial functions, the dominant behavior is that of the highest-degree term.
For other functions, the dominant behavior will typically be governed in some other way. Here, the rate of growth of the x·log(x) function is determined by log(x), which has decreasing slope as x increases.
Only answer selection B has a highest-degree term of x^2, so only that one exhibits O(x^2) behavior.
Answer:
C
Step-by-step explanation:
Parallel line slopes are always the same.
Answer:
y=8x
Step-by-step explanation:
The graph starts at the origin so there won't be a y intercept and the slope its 8 because every book costs 8 dollars. Therefore, the equation will be y=8x. Hope this helped
Answer:
B
Step-by-step explanation:
There are 12 inches in 1 feet, so
5 feet = 5 * 12 = 60 inch
6 feet = 6 * 12 = 72 inch
So, we can say most adult humans are between 60 to 72 inches tall
The model is 7 inches tall. So, from the answer choices, 7 * 10 = 70 [the number that is in between 60 to 72]. Thus we can take the model to be 1/10th of the original.
So the scale factor is 1/10, or option B
