Find the range of the function with domain {–3, 1, 4.5}. f(x) = 2x^2 a. {12, 4, 8} b. {–12, 4, 18} c. {–18, 2, 40.5} d. {18, 2, 40.5}

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
