vo 0 R Fig.10.14 The range R of a projectile varies jointly as the square of its ini- tial volocity 1 and the sine of twice the angle o from the hori- zontal at which it is fired. See Fig. 18.14. A bullet for which 850 m/s and 0 - 22.0° has a range of 5.12 x 104 m. Find the range if v - 750 m/s and 6 - 43.2º. m/s

i can

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
