Answer: No, because ABC is not a right angle.
Step-by-step explanation: In triangle ABC, the three angles add up to 180
So angle B = 180 - 48 - 47 = 85.
Attached is a screenshot of spreadsheet used to do this problem.
You will see the excel functions used for each column. The average score is highlighted in blue.
Answer: The graph is attached.
Step-by-step explanation: The given functions whose graphs are to be compared are as follows:

In the attached figure, the graphs of both (A) and (B) are shown. We can easily see see from there, the shapes of both the graphs are same.
But, at x = 0, y = ∞ and at x = ∞, y = 0 in graph (A).
At x = 0, y = ∞ and at x = ∞, y = 6 in graph (B).
Thus, the comparison can be seen in the figure very clearly.
Step-by-step explanation:
numbers one two and three are correct
The answer is B, 8. 2 exponent 3 is 8 because to find an exponent multiply the base by itself with the exponent number: 2*2*2 which is 8.
