that is a rational number.
Let

Then

and solving for x gives






By the quadratic formula,

but x must be a positive number, so only the positive square root solution is valid.

We identify a = c = 3 and b = 2, so a + b + c = 8.
Answer:
19
Step-by-step explanation:
ez pz lemon squeezie
You take the derivative of the position equation s(t) = -3 + 4

and you get v(t) = 8t
now plug in 5
v(5) = 40
40 m/s
is your answer
If this can be modelled by exponential decay, therefore
the function must be in the form of:
A = Ao (1 + r)^t
where A is the final value, Ao is the initial = 15000, r
is the rate of decay = -0.0015, t is time = 2010 – 1990 = 20
A = 15,000 (1 – 0.0015)^20
A = $14,556.36
