Figure 2 shows the circle PQRT with center O and radius 10cm. AQB is a tangent to the circle at point Q. The straight lines AO and BO intersect the circle at point P and R respectively. OPQR is a rhombus. The angle of BQR is 30°. ACB is an arc of a circle, center 0. Calculate;- the angle a in term of a b. the length of the arc ACB. R c. the area of the shaded region.

step-by-step explanation:

d is correct

step-by-step explanation:

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

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 !
