PLZ SOMEONE HELP ME WITH THIS I'LL GIVE U FREE POINTS :The function f(x) = 2x2 + x + 5 represents the number, in tens, of jars of pickles, Denise expects to sell x weeks after launching her online store. What is the average rate of change over the interval 1 ≤ x ≤ 2?

7

Step-by-step explanation:

f(2) = 2(2)² + 2 + 5 = 15

f(1) = 2(1)² + 1 + 5 = 8

Average rate of change:

[f(2) - f(1)]/(2 - 1)

(15-8)/1

Step-by-step explanation:

f(2) = 2(2)² + 2 + 5 = 15

f(1) = 2(1)² + 1 + 5 = 8

Average rate of change:

[f(2) - f(1)]/(2 - 1)

(15-8)/1 = 7

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

non hispanic white population

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
