We know that the domain is actually the number of rolls
that she gets because it is the input variable in the equation f (r) = 40 r + 26. The number of rolls that
she can get can never be a negative number nor a zero nor a decimal number.
However she can only get up to 10 rolls. Therefore the answer is:
all integers from 1 to 10, inclusive
The unit rate is 12.65 per hour.
Answer:
k = - 2
Step-by-step explanation:
Given α and β are the zeros of x² - 6x + k = 0 , with
a = 1, b = - 6 and c = k , then
α + β = - 
= - 
= 6
αβ = 
= 
= k
Then solving
(α + β)² - 2αβ = 40
6² - 2k = 40
36 - 2k = 40 ( subtract 36 from both sides )
- 2k = 4 ( divide both sides by - 2 )
k = - 2
I believe the answer to your question is 10/37.
The total of candies inside the bag was initially 38. Since a blue candy has already been picked and cannot be picked and cannot be replaced then the total number of candy remaining in the bag is 37. So the probability of choosing a red candy is now 10/37
