Pls solve clearly with answer circled

1. In a test flight of the Mccord Terrier, Mccord Aviation's experimental VTOL (vertical takeoff and landing) aircraft, it was determined that t seconds after liftoff, when the craft was operated in the takeoff mode, its altitude (in feet) was given by h() = 124 -13+ 312 . Which is the 32 expression for the craft's acceleration at time t? a. a(t) =0.7512 -3t +6 b. a(t) =0.37512 -61+6 c. a(t) =0.003t2 -0.167t +0.167 d. a(t) =0.12513 -312 + 61 7. Given the diagram of vectors, which of the following represents the angles in standard form? 20* a. OR =20%, 60 =140 b. OR = 20, 0 =50 C. OR =1100, 0. =230 d. OR =170, 0 =220 11. Calculate the limit using concepts taught in this course: x'-x'+x-3 lim x-700 x + 5x+3 12. Given the vectors shown, find the magnitude and angle in standard position of the sum F + G. G - 278 F - 208
