Answer:
A
Step-by-step explanation:
We are given that:
And we want to find:
Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:
Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.
Our answer is A.
The double bar graph shows the number of imports and exports for a company in a certain week.
On how many days was the number of exports greater than the number of imports?
Answer: From the given double bar graph, we clearly see:
Number of imports for a company on Monday = 15
Number of exports for a company on Monday = 7
Number of imports for a company on Tuesday = 18
Number of exports for a company on Tuesday = 9
Number of imports for a company on Wednesday = 14
Number of exports for a company on Wednesday = 14
Number of imports for a company on Thursday = 15
Number of exports for a company on Thursday = 6
Number of imports for a company on Friday = 9
Number of exports for a company on Friday = 19
From the above information, we clearly see that only on Friday the number of exports are greater than number of imports. Therefore, there is only 1 day when the number of exports greater than the number of imports.
Hence the option D. 1 is correct
