A surveyor needs to find the distance from point a to point b across a canyon. She places a stake at a and her coworker places a stake at b on the other side of the canyon. The surveyor then locates c on the same side of the canyon as a CA AB. A fourth stake is places at E, the midpoint of CA. Finally, a stake is placed at D such that CD CA and D, E, and B are sited as lying along the same line. Explain how the surveyor can use the triangles formed to find AB. If AC=1300 meters, DC =550 meters, and DE=851.5 meters, what is AB? Explain your reasoning.

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
