The position function for a particular object is s equals negative 31 over 2 times t squared minus 44 times t plus 85. which of the following statements is true?

The initial velocity is - 44

Step-by-step explanation:

S = - 44t + 85 .

Differentiating once to get the velocity , we have

V = - 31t - 44

The initial velocity means that t = 0 , substitute this into the equation , we have

V = -31 (0) - 44

V = -44

Therefore, the initial velocity is -44

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer: y=4000x+14000
