Answer:
The value of x at this instant is 3.
Step-by-step explanation:
Let , we get an additional equation by implicit differentiation:
(1)
From the first equation we find that:
(2)
By applying (2) in (1), we get the resulting expression:
(3)
If we know that and , then the first derivative of x in time is:
From (1) we determine the value of x at this instant:
The value of x at this instant is 3.
Answer:
b. y = 3(x+2)^2 + 5
Step-by-step explanation:
The vertex form of a parabola is
y = a(x - h)^2 + k where (h, k) is the vertex.
Here h = -2 and k = 5 so the following could be the required equation\;
y = 3(x+2)^2 + 5
