Answer: The correct option is
(c)
Step-by-step explanation: We are given a right-angled triangle PQR, with m∠R = 90°, m∠Q = 60° and m∠P = 30°.
We are to select the ratio that represents sin P.
We know that sine of any acute angles is the ratio of the length of the perpendicular to the length of the hypotenuse.
For the acute angle P, we have
perpendicular = RQ and hypotenuse = PQ.
Therefore, we get
Thus, (c) is the correct option.

Answer:
From <u>fourth</u> month onwards, the growth rate of is greater than that of
.
Step-by-step explanation:
Given:
The growth rates of both bank accounts are given as:
Now, as per question, we need to find the value of 'x' when the value of . Or,
Now, we can do this by checking the values of 'x' by hit and trial method.
Let . The inequality becomes:
Let . The inequality becomes:
Let . The inequality becomes:
Let . The inequality becomes:
Therefore, the value of 'x' for which is 4.
So, from the fourth month onwards, the balance in becomes greater than
.
The graphical solution is shown below to support the same.
From the graph, we can conclude that after the 'x' value equals 3.4, the graph of lies above of
. Hence,
for
