In Δ PQR, PQ = 17.4 m and PR = 7.6 m. K lies on QR such that ∠ PKQ = 137 °. find (i) ∠ QPR (ii) the length of QK using the trigonometric ratios

Ineed someone to me answer my question i have to have this done and knocked out

What is the slope of a line that is perpendicular to the line shown on the graph? –4 4

The change in water level of a lake is modeled by a polynomial function, w(x). described how to find the x-intercepts of w(x) and how to construct a rough graph of w(x) so that the parks department can predict when there will be no chage in the water level. you may create a sample polynomial of degree 3 or higher to use in your explanations.
