Answer 1

Answer:

Answer:

∠ $ACD=60$ ° or B

Step-by-step explanation:

$110+120+70= 300$

$360-300=60$

Answer 2

Answer:

Answer:

B 60

Step-by-step explanation:

Do not let all the extra triangles on the outside trip you out. The shape is a trapezoid which total should equal 360. Add all the angles up and subtract from 360 to get 60

Hope this Helps :)

uppose a small cannonball weighing 16 pounds is shot vertically upward, with an initial velocity v0 = 290 ft/s. The answer to the question "How high does the cannonball go?" depends on whether we take air resistance into account. If air resistance is ignored and the positive direction is upward, then a model for the state of the cannonball is given by d2s/dt2 = −g (equation (12) of Section 1.3). Since ds/dt = v(t) the last differential equation is the same as dv/dt = −g, where we take g = 32 ft/s2. If air resistance is incorporated into the model, it stands to reason that the maximum height attained by the cannonball must be less than if air resistance is ignored. (a) Assume air resistance is proportional to instantaneous velocity. If the positive direction is upward, a model for the state of the cannonball is given by m dv dt = −mg − kv, where m is the mass of the cannonball and k > 0 is a constant of proportionality. Suppose k = 0.0025 and find the velocity v(t) of the cannonball at time t.
