← [:] -[3] = Y₁ 5 into y₁ and maps e2 into y₂. Find the images of Let e₁ = 0 The image of and e₂= 4 -4 is and Y2 = 4 -4 8 and let T: R² R² be a linear transformation that maps e₁ and X₁ X2 ir

I'm stuck on figuring out how to do this problem correctly. Please help

i already figured out the answer to the first question and really just wanted to find the process by which i could get the third answer

Here’s a look at a map of the east side of Dubuque, Iowa. It shows a driving path from a casino on the river to a golf course on the other side. According to the maps app on my phone, the driving distance is 3.0 miles. We’re most interested in the graphic at the bottom left, which indicates that 1 inch on the map (measure if you don’t believe me) corresponds to 2,000 feet in real life.   If a 50-foot boat were on the river, how big would it appear on the photo? Round to three decimal places.
