Option C: center (1,2) and radius sqrt 5
Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
Answer:
The problem can't be factor
Step-by-step explanation:
In order to answer, I would first need to know Jana's speed, not that she biked at a constant rate.
Ok so the first one is 225 miles but i can't do the graph
and i'm not great at math so give me a bit
