A particle moves along a straight line. For Osts 5, the position of the particle is given by s(t) = 3t +412 - 13
a) What is the average velocity of the particle over the interval Osts 4?
b) Find a general expression for the velocity of the particle as a function of time, u(t), and determine
the value of v att = 2. Is the particle traveling to the left or the right at this point? Justify your
answer.
c) Find all times t during the interval 0 Sts 5 that the particle changes direction. Justify your
answer.
d) At t = 4, is the speed of the particle increasing or decreasing? Justify your answer.

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
