When a raindrop falls, it increases in size and so its mass at time t is a function of t, m(t). the rate of growth of the mass is km(t) for some positive constant k. applying newton's law of motion to the raindrop results in dt where v is the velocity of the raindrop (directed downward) and g is the acceleration due to gravity. the terminal velocity vter of the raindrop is, uter-t-oo find an expression for the terminal veloc ity in terms of g and k
step-by-step explanation: for the student to be considered for the tutoring or extension activities, his/her score must be 20 points lower or higher than the average.
the average is given as 105, that means:
minimum score to be considered = 105 - 20 = 85
maximum score to be considered = 105 + 20 = 125
if p represents the performance of a student, then this inequality will be represented as follows:
85 ≤ p ≤125
hello : 4xy (2x +3y)
8x²y +12xy² = 4xy (2x +3y)
y= -1/4x + 9/8

an event with a probability of 0 is impossible.
an event with a probability of 1 is certain.
probability is typically expressed in terms of a fraction between 0 and 1 where the denominator is the total number of outcomes and the numerator is the number of desired outcomes. since probability is expressed as a fraction, if the probability is 0, that means it is impossible, or there is no chance that the event can happen. however, if the probability is 1, that means that the event is certain to happen and the odds are completely in your favor that the event will happen.
