A surveyor measures the distance across a straight river by the following method (Fig. P1.6). Starting directly across from a tree on the opposite bank, she walks d = 100 m along the riverbank to establish a baseline. Then she sights across to the tree. The angle from her baseline to the tree is 0 = 35.0. How wide is the river? Figure P1.6

What is the speed of a car going v=1.000 mph in SI units? Notice that you will need to change miles to meters and from hours to seconds. you can do each conversion separately. Use the facts that 1 mile=1609 m and 1 hour= 3600s
Paleontologists use the function W(x) = 4√/2x to estimate the walking speed of a dinosaur, W(x), in feet per second, where x is the length, in feet, of the dinosaur's leg. What is the walking speed of a dinosaur whose leg length is 6 feet? Express the answer in simplified radical form. Then use the function's graph to estimate the answer to the nearest foot per second. Walking speed (feet per second) feet per second. (Round to the nearest whole number as needed.) Dinosaur Walking Speeds W(x) = 4√2x Write the walking speed of a dinosaur whose leg length is 6 feet as a simplified radical. feet per second. (Simplify your answer.
