A ball is thrown upward at time t=15t=15 s on planet Ubuntu, and its acceleration from time t=15t=15 s to t=23t=23 s is given by the function a(t)=4t−14 m/s2a(t)=4t−14 m/s2. Use 44 time intervals of equal length to overestimate, and then underestimate, the relative velocity of the rising ball from time t=15t=15 s to t=23t=23 s. (a) Overestimate

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less

step-by-step explanation:

the answer would be 44.79

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
