Answer:
Step-by-step explanation:
The key to solving this problem lies in understanding that the domain of the square root function includes ONLY zero or positive numbers.
In this case, we set 4x - 3 ≥ 0.
Solving for 4x: 4x ≥ 3. Therefore, x ≥ 3/4.
The domain of the given function is [3/4, ∞ ).
Answer:
The equation which expresses the ratio of the circumference to the diameter of a circle is
⇒ D
Step-by-step explanation:
π is the ratio between the circumference of the circle and the length of its diameter
, where
- C is the circumference of the circle
- d is the diameter of the circle
∵ The circumference of the circle is C
∵ The radius of the circle is 15 units
∴ r = 15 units
- Find the diameter of the circle
∵ The diameter of the circle d = 2 r
∴ d = 2(15) = 30 units
∴ The diameter of the circle is 30 units
∵
∵ d = 30 units
∴ 
The equation which expresses the ratio of the circumference to the diameter of a circle is
