Answer:
Let's suppose that each person works at an hourly rate R.
Then if 4 people working 8 hours per day, a total of 15 days to complete the task, we can write this as:
4*R*(15*8 hours) = 1 task.
Whit this we can find the value of R.
R = 1 task/(4*15*8 h) = (1/480) task/hour.
a) Now suppose that we have 5 workers, and each one of them works 6 hours per day for a total of D days to complete the task, then we have the equation:
5*( (1/480) task/hour)*(D*6 hours) = 1 task.
We only need to isolate D, that is the number of days that will take the 5 workers to complete the task:
D = (1 task)/(5*6h*1/480 task/hour) = (1 task)/(30/480 taks) = 480/30 = 16
D = 16
Then the 5 workers working 6 hours per day, need 16 days to complete the job.
b) The assumption is that all workers work at the same rate R. If this was not the case (and each one worked at a different rate) we couldn't find the rate at which each worker completes the task (because we had not enough information), and then we would be incapable of completing the question.
The answer is A since you just plug in -2for all the x’s
The x-intercept and the asymptote of g(x) are x = 5 and x = 4, respectively
<h3>How to determine the x-intercept and asymptote of g(x)?</h3>
The equation of the function is given as:
g(x) = log3 (x - 4)
Set the function to 0, to determine the x-intercept
log3 (x - 4) = 0
Express the function as an exponential function
x - 4 = 3^0
Evaluate the exponent
x - 4 = 1
Add 4 to both sides
x = 5
Set the radical to 0, to determine the asymptote
x - 4 = 0
Add 4 to both sides
x = 4
Hence, the x-intercept and the asymptote of g(x) are x = 5 and x = 4, respectively
