The atmospheric pressure P on a balloon or in aircraft decreases with increasing height . This pressure measured in Millimeters of mercury , is related to the height H (in kilometers) above sea level by the formula p=760e ^ -0.145h. See photo for formula and answer following questions. A.) find the height of an aircraft if the atmospheric pressure is 295 millimeters of Mercury. B.) find the height of a mountain if the atmospheric pressure is 695 millimeters of mercury.

Which expression calculates the speed in meters per second of an object that travels a distance of 100 m every 20 seconds

Yuto and hila attempted to solve the same inequality. their work is shown below. which statement is true about the work shown above? yuto is correct because he isolated the variable correctly and reversed the inequality symbol. yuto is incorrect because he should not have reversed the inequality symbol. hila is correct because she isolated the variable correctly and reversed the inequality symbol. hila is incorrect because she should not have reversed the inequality symbol.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
