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
So the equation is 1.5(1.1) +7.6
1. Multiply 1.5* 1.1 = 1.65
2. Add 1.65 +7.6= 9.25
I would have to say the answer is 9.25
The first solution is quadratic, so its derivative y' on the left side is linear. But the right side would be a polynomial of degree greater than 1, so this is not the correct choice.
The third solution has a similar issue. The derivative of √(x² + 1) will be another expression involving √(x² + 1) on the left side, yet on the right we have y² = x² + 1, so that the entire right side is a polynomial. But polynomials are free of rational powers, so this solution can't work.
This leaves us with the second choice. Recall that
1 + tan²(x) = sec²(x)
and the derivative of tangent,
(tan(x))' = sec²(x)
Also notice that the ODE contains 1 + y². Now, if y = tan(x³/3 + 2), then
y' = sec²(x³/3 + 2) • x²
and substituting y and y' into the ODE gives
sec²(x³/3 + 2) • x² = x² (1 + tan²(x³/3 + 2))
x² sec²(x³/3 + 2) = x² sec²(x³/3 + 2)
which is an identity.
So the solution is y = tan(x³/3 + 2).

The computation shows that the value of blue which is represented by x is 12.
<h3>How to calculate the value?</h3>
From the information given, it was stated that 30 people were in the kindergarten.
Green = 10
Red = 8
Blue (x) = 30 - (10 + 8)
= 30 - 18
= 12
Since the teacher want to paint the class with the most favorite color, the appropriate color to use will be blue.
