Based on the Excel table, the two columns that are mislabeled are:
- First order date.
- Most recent order date.
<h3>What is an Excel table?</h3>
An Excel table can be defined as a rectangular range of data set in a spreadsheet document, which consist of cells that are arranged in rows and columns.
In this scenario, we can logically deduce that the "First order date" and "Most recent order date" are the two columns that are mislabeled because the date for the first order should normally come before the most recent order.

Answer:
sec(4x) + C
Explanation:
original problem: ∫sec(4x)tan(x)dx
use integration by substitution (u-sub) by setting u = 4x
if u = 4x, then du/dx = 4 and du = 4dx (dx = du/4)
after substitution the integral is ∫sec(u)tan(u)(du/4)
move the 1/4 out of the integral by using the integral Constant rule to form 1/4∫sec(u)tan(u)du
the anti-derivative of sec(u)tan(u) is sec(u), memorize your trigonometric derivatives!!!!
after integration, we get sec(u)/4 + C , now plug u back into the equation
sec(4x) + C is the general solution
Sales tax is regressive, the second is progressive, and the third is proportional.
Think about it. 65 mph means you go 65 miles in one hour, so in 2 hours you go 65×2 miles, in 3 hours you go 65×3 miles, and in 3.5 hours you go 65 × 3.5 miles.
Hope this helped
One movement that came to mind for me was the “Black Lives Matter” group and movement. The moment that group was created the government and F.B.I. thought of it as them becoming a security threat. I believe formations of those groups shouldn’t require approval, but rallies or parades should.
