Since factors need to show that a number can be divided by another and 6*3=18, C is the answer.
Step-by-step explanation:
For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.
=> (-z)² - 4(z - 5)(5) = 0
=> z² - 20(z - 5) = 0
=> z² - 20z + 100 = 0
=> (z - 10)² = 0
Therefore z = 10.
Answer:
A
Step-by-step explanation:
W(P(t)) represents a patients's waiting time W() as function of the time of day P(t)
An estimate for the number of ducks would be 62.
There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.
A.) 38.92 the sales tax is $2.97 so 35.95 + 2.97 = 38.92
