Asurveyor has determined that a mountain is
h = 2470
ft high. from the top of the mountain he measures the angles of depression to two landmarks at the base of the mountain and finds them to be 42° and
c = 39°.
(observe that these are the same as the angles of elevation from the landmarks as shown in the figure below.) the angle between the lines of sight to the landmarks is 68°. calculate the distance between the two landmarks. (round your answer to the nearest integer.)

Which of the following circles have their centers on the x-axis? check all that apply.

Which term describes the point where the perpendicular bisectors of the three sides of a triangle intersect?

Suppose that a customer is purchasing a car. he conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. he conducts this experiment 15 times on each car and records the number of miles driven. full data set car 1 238238 216216 205205 212212 240240 274274 297297 252252 260260 247247 257257 243243 296296 243243 290290 car 2 245245 204204 215215 209209 251251 165165 221221 295295 172172 287287 268268 305305 320320 260260 297297 describe each data set, that is determine the shape, center, and spread. sample mean for car 1 x overbar equalsx=216216 mi / 10 gal (type an integer or decimal rounded to one decimal place as needed.) sample mean for car 2 x overbar equalsx=209209 mi / 10 gal (type an integer or decimal rounded to one decimal place as needed.)
