Answer:
The domain is and its range is
The y-intercept is (0,3).
Step-by-step explanation:
Consider the parent function Its domain is
and its range is
The graph of the function is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the domain and will change the range of the function, thus the domain is
and its range is
To find th y-intercept you have to find y at x=0:
Hence, the y-intercept is (0,3).
For the first inequality, subtract 5 from both sides to get
For the second inequality, subtract 1 from both sides to get
Divide both sides by 6:
So, x has to be greater than or equal to -2, or less than -5, which is option D
Answer:
The value of radius r is 50
Step-by-step explanation:
Given as :
The measure of two circles as
Circumference = c Circumference = c'
Diameter = d Diameter = d'
Radius = r Radius = r'
And
= 5
d' = 20
∴ circumference of circle = =
Or, =
Or, 5 =
Or, 5 =
∴ 2 × r = 5 × 20
I.e r = 50
Hence The value of radius r is 50 Answer
