P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..
Answer: t = 3seconds
Step-by-step explanation:
To find the zero means we will equate the function to zero and then solve, that is
+ 32t + 48 = 0
by factorizing , we have
(t+1)(-16t+48) = 0
Therefore:
t = -1 or t = 3
since time can not be negative , then , t = 3 seconds
Answer:
-1
Step-by-step explanation:
f(-1) = (-1)² - 5(-1) -2 = 4
f(5) = (5)² - 5(5) -2 = -2
rate of change = (f(-1) - f(5)) / -1 - 5 = (4 - -2) / (-1 - 5) = 6 / -6 = - 1
