mali aaudina so sorry and again please don't asked me
a. We can parameterize
by


with
. Then

b. We can parameterize the opposite direction by instead setting


with
. Then

which gives the same value as in part (a).
Answer: y = 5x - 7
Step-by-step explanation:
y = mx + b, where m = slope
We plug in the point, where x = 2, and y = 3
y = 5x - b
3 = 5(2) - b
3 = 10 - b
b + 3 = 10
b = 7
y = 5x - 7
This is a simple proportion
1100 : 13 = 41000 : x
For every 1100 discs, 13 are defective, meaning that there will be an X number for each 41000
13 * 41000 = 1100 * x
13 * 410 = 11 * x
5330 = 11 * x
x = 5330/11
x = 484.5
That means that for every 41000, approximately 485 discs will break down.
Answer:
Question 13: For age groups y=1 and y=1.3 response is 8 microseconds.
Question 14: The club was making a loss between 11.28 and 4.88 years.
Step-by-step explanation:
Question 13:
The age group y for which the response rate R is 8 microseconds is given by the solution of the equation

We graph this equation and find the solutions to be

Since only positive solutions for y are valid in the real world we take only those.
Thus only for age groups y=1 and y=1.3 the response is 8 microseconds.
Question 14:
The footbal club is making a loss when 
Or

We graph this inequality and find the solutions to be
and 
Since in the real world only positive values for t are valid, we take the the second solution to be true.
Thus the club was making a loss in years
