Answer 1

Give the signs of the trigonometric functions. 22) cos(523º) and tan (523) A) -and- B) -and- - and D) and = cos(523) = cos ( 360 +163) = cos(163) Negative =) ten(523) = ten(360 +163) Eten 163 Negative Find all values of e, if is in the interval 10,360") and has the given function value. 23) sin 0 - 43 A) 150 and 210 B ) 609 and 300 9 2109 and 330 23) — and 120 O = 60, 180-60 = Gó, 128 2 4) Solve the problem. Round to the nearest whole number. 24) The grade resistance Fof a car traveling up or down a hill is modeled by the equation F= W sin 0, where W is the weight of the car and is the angle of the hill's grade (0> for uphill travel, <for downhill travel). What is the grade resistance of a 3000-lb car traveling uphill on a 30 grade (0-3)? A) -157 lb P67 lb 99-30036 D) 3003 F = 3000 sins F=15746 Solve for the requested quantity. 25) sin A 25) — zi z=122793 = 185 B) 4.5000 A) 0.97 90.2169 D10.2 sina SINGLE =0.9762
