Some students make a parade float with the letter H on it. Draw lines to divide the shape into rectangles. Then find its area. A 38 square feet B 46 square feet C 40 square feet D 29 square feet

Find the measures of the angles of the triangle whose vertices are A = (-1,0), B = (2,1), C = (1,-2).

I am a newby to Kalmar filters, but after some study, I think I understand how it works now. For my application, I need a Kalmar filter that combines the measurement input from two sources. In the standard Kalmar filter, that is no problem at all, but it assumes that the measurement inputs from the two sensors are available at the same times. In my application, there is one new measurement from sensor 'b' for every 13 measurements of sensor 'a'.That is, 12 out of 13 times, the measurement of sensor 'b' is missing.
How would you handle that normally? Do you simply use the predicted measurements values as substitute for the missing ones? Does that not lead to overconfidence in the missing measurements? How else can it be handled?

Fernando and Risa are factoring ${\displaystyle 5x^2-x-6}$. They each made a chart below and selected a pair of integers. Which student is correct? Explain your reasoning.
Fernando:
$\begin{array}{|cc|}\hline Factors& sum\\ 1.-6& -5\\ -1.6& 5\\ 2.-3& -1\\ \hline\end{array}$
Risa:
$\begin{array}{|cc|}\hline Factors& sum\\ -3.10& 7\\ 3.-10& -7\\ 5.-6& -1\\ \hline\end{array}$
Who is correct?

Using integration by parts, show that for any positive integer n, $\int x^n{e}^n=x^n{e}^x-n\int x^{n-1}{e}^{x}dx$
Use the above formula to determine $\int x^4{e}^{x}dx$
