The cost C, in dollars, to have medical records transcribed is a function of time, t in hours. A physician's group spends C(t) =
Contact [7]

Answer:

B. $39550

Step-by-step explanation:

The expression for the function is not well-formatted, find the correct format in the solution bellow

Step one:

given data

We are told that the function of the cost is

C(t) = 0.04t^3- 0.1t^2 + 5.5t

instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above

substituting we have

C(t) = 0.04(100)^3- 0.1(100)^2 + 5.5(100)\\\\\C(t) = 0.04*1000000- 0.1*10000 + 5.5*100\\\\C(t) = 40000-1000+550\\\\C(t) = 39550

$39550

One number is 16 more than a second number. The sum of the first number and twice the second number is 139. What is the answer ?
Nezavi [6.7K]
Answer first number  = 57  second number = 41
x= 16 + y
x + 2y = 139

16+ y + 2y =139
16 + 3y =139
16-16 +3y = 139-16
3y = 123
3/3y = 123/3
y= 41

x= 16+y
x = 16+41
x= 57
