Which of the following statements is true only if triangles EFI and GFH are similar? Line segments EG and HI intersect at point F, forming triangles EFI and HFG Line a intersects with both triangles at point F. two segment FI equals three segment FH Lines EI and HG are parallel Points E, F, and G are collinear segment EI over segment FI = segment GH over segment FH

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
