Answer:
The correct option is 1
Step-by-step explanation:
Snowball sampling is a typr of sampling technique which is used in investigating hard to reach groups. Existing subjects are asked to nominate further suubjects known to them, thereby making the sample increase like a rolling snowball
The parent function of

is

The diagrams below show step by step transformation
As we can see from the graph

, the amplitude of the function is 3, period of

, phase shift of π and midline y=2
The answer is 25 because
5*5=25
1225*(1.578*10^-5)=1.933*10^-2
1.578*10^-5= 0.00001578
1225*0.00001578=0.0193305
0.0193305=1.933*10^-2
Given:
QR is parallel to RS.
To find:
The value of x.
Solution:
In the given figure, we have,


Using basic proportionality theorem (BPT), we get


On cross multiplication, we get




Divide both sides by -6.


Therefore, the value of x is 5.
