The equations

2x^2+9x-5=0

and

2\left(t-\dfrac12\right)^2+9\left(t-\dfrac12\right)-5=0

are really the same, we're just setting x=t-\dfrac12, or t=x+\dfrac12.

2x^2+9x-5=(2x-1)(x+5)=0\implies x=\dfrac12,x=-5

So we get

t=\dfrac12+\dfrac12=1,t=-5+\dfrac12=-\dfrac92

The number of views on a viral video can be modeled by the function S(t)=9600(3)^t+2. Write an equivalent function of the form S
anyanavicka [17]

Answer:

The equivalent expression would be;

S(t) = 86,400•3^t

Step-by-step explanation:

Here, we want to make a transformation

From what we have;

S(t) = 9,600(3)^(t + 2)

From indices, we know that;

x^(a + b) = x^a•x^b

Thus, we have it that;

S(t) = 9600•3^t•3^2

S(t) = (9 * 9600) * 3^t

S(t) = 86,400•3^t
