Answer:

S(t) = 4.725t + 478.25

S(t) = 4.725(42)+478.25

S(t) = 676.7

Step-by-step explanation:

In the question, score is a function of time, that means time is the x-axis, while score is the y-axis.

Order the pairs to get:

(30,620) and (70, 809)

With these values, you use the the equation \frac{x2-x1}{y2-y1} to get the slope m.

\frac{70-30}{809-620}  = 4.725

Use this equation and input any ordered pair to get the final function.

y-y1 = m(x-x1)

y-620 = 4.725x-141.75

y = 4.725x + 478.25

Replace x with t and y with S(t) to fit the x & y axis of the question.

if the equation of a parabola is y = 7(x-4)^2+v and its vertex is (4,-2) , what is the value of v in the equation
N76 [4]
The vertex form of a quadratic function: y = a(x - h)² + k

vertex (h; k)

We have: y = 7(x - 4)² + v
vertex: (4; -2)

therefore: v = -2
