Answer:

Step-by-step explanation:
First, we'll find the length of the radius using distance formula and the coordinates (0,0) and (7,0)
Distance Formula = 
R = 
R = 
Radius = 7 units
<u><em>Now, Equation of circle:</em></u>

Where (a,b) = (0,0) So, a = 0, b = 0 and R = 7 units
=> 
=> 
This is the required equation of the circle.
Answer: A
Step-by-step explanation:
You’re learning the definition of the derivative aren’t you. Just plug in x+h and do FOIL. Then multiply each term by -3 because of -3 infront of the square.
-3(x+h)^2 - 2(x+h) +4
-3[x^2 + 2xh + h^2] - 2x - 2h + 4
-3x^2 - 6xh - 3h^2 - 2x - 2h + 4
Your answer is D
