Sum means add.

So, we'd need to add

4 5/6 + 3 5/6

5/6 + 5/6 = 10/6, or 1 4/6, or 1 2/3.

4 + 3 = 7

7 + 1 =8

8 2/3 is your answer.

Glad I could help, and good luck!

The profits of mr cash’s company is represented by the equation p(t)=-3t^2+18t-4, where p(t) is the amount of profit in hundreds

Anika [276]

Answer:

$2300000- max profit
5.77 years into operation - zero profit time

Step-by-step explanation:

Given function:

p(t)= -3t^2 + 18t - 4

It is a quadratic function with general form of y = ax^2 + bx + c

It opens down if a < 0 and gets maximum value at vertex which is determined at x = -b/2a

For the given function vertex is:

t = -18/-3*2 = 3

Maximum value of p is:

p(3) = -3*3^2 + 18*3 - 4 = -27 + 54 - 4 = 23 ($2300000)

The time when profit is zero:

-3t^2 + 18t - 4 = 0
3t^2 - 18t + 4 = 0
t = (18 ± √18² - 4*3*4)/2*3 = (18 ± √276)/6 = (18 ± 16.61)/6
t = (18 - 16.61)/6 = 0.23 this is the time when company has just started to make profit, it is not applicable as is the past time
t = (18 + 16.61)/6 = 5.77 years into operation, after this time there will be no profit
