Step-by-step explanation:
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15
Using the values, we get:
So, the correct answer to this question are option B and D
Answer:
B: T = ½R
Step-by-step explanation:
From the given graph, we see the following;
When T = 2, R = 4
When T = 3, R = 6
When T = 4, R = 8
When T = 5, R = 10
Looking at those values, we can see a pattern where R is always equal to 2T.
Or T = ½R
Thus, option B is the answer.
