Solution:
we are given that
Both circle Q and circle R have a central angle measuring 140°. The area of circle Q's sector is 25π m^2, and the area of circle R's sector is 49π m^2.
we have been asked to find the ratio of the radius of circle Q to the radius of circle R?
As we know that
Area of the sector is directly proportional to square of radius. So we can write
Answer:
1)
2)
3)
Step-by-step explanation:
General form of sin function is
Where A is Amplitude
B is
C is Mid line
1) Given : A sine function has the following key features
Frequency =
Period is
Amplitude= 2
Mid line y= 2
Y intercept (0,2)
This function is NOT a reflection of its parent function of the x-axis
Solution : We put the value in the general form of sin function
A= 2 , , C=2
2) Given : A sine function has the following key features
Period = 4
Amplitude = 3
Mid line y = -1
Y intercept (0,-1)
Solution : We put the value in the general form of sin function
A= 3 , , C=-1
3) Given : A sine function has the following key features
Period =
Amplitude = 2
Mid line y = -12
Y intercept (0,-2)
Solution : We put the value in the general form of sin function
A= 2 , , C=-2
