The owner of a van installs a rear-window lens that has a focal length of -0.301 m. When the owner looks out through the lens at a person standing directly behind the van, the person appears to be just 0.242 m from the back of the van, and appears to be 0.343 m tall.(a) How far from the van is the person actually standing?(b) How tall is the person?

Find the vertex(use the completing the square method), findthe x- and y-intercepts, and sketch the graph offunction. y = 2x2 + 4x - 1

What’s #16 asking me and how do i solve it?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
