(Enter your answer using interval notation.) (c) Find the interval(s) on which f is concave upward. (Enter your answer using interval notation.) (d) Find the interval(s) on which f is concave downward. (Enter your answer using interval notation.) (e) Find the coordinates of the inflection point(s). (Order your answers from smallest to largest x, then from smallest to largest y.) (x, y)

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

54.667> 54.666

17.889< 17.899

these are both true

humans' internal body temperature is a great example of homeostasis. when an individual is healthy, his or her body temperature retains a temperature 98.6 degrees fahrenheit. the body can control temperature by making or releasing heat. the maintenance of healthy blood pressure is an example of homeostasis.
