#1 - a) 11.4018
#2 - d) 7.62
#3 - a) 10.7238
#4 - b) 6.57
Explanation
#1 - The initial guess is 11.4022. We first divide 130 by this guess:
130÷11.4022 = 11.40130852
We now average this number with the initial guess:
(11.40130852 + 11.4022)/2 ≈ 11.4018
#2 - The initial guess is 7.8. We divide 58 by this guess:
58÷7.8 = 7.435897436
We now average this number with the initial guess:
(7.435897436 + 7.8)/2 = 7.617948718 ≈ 7.62
#3 - The initial guess is 10.7262. We divide 115 by this guess:
115÷10.7262 = 10.72141112
We now average this number with the initial guess:
(10.72141112 + 10.7262)/2 = 10.72380556 ≈ 10.7238
#4 - The initial guess is 6.9. We divide 43 by this guess:
43÷6.9 = 6.231884058
We now average this number with the initial guess:
(6.231884058+6.9)/2 = 6.565942029 ≈ 6.57

Answer:
Her weight is increase by 18 lbs over past five years and the slope is 3.6 lbs per year.
Step-by-step explanation:
Given information: Estelle weight is
At age 16 = 110 lbs
At age 21 = 128 ibs
Increase in her weight over the past 5 years is the difference of weight at age 21 and at age 16.
Increase in her weight over the past 5 years = 128 - 110 = 18
Her weight is increase by 18 lbs over past five years.
Let x=age and y=weight, then the weight function passes through the points (16,110) and (21,128).
If a line passes through two points
and
, then the slope of the line is

Using the above formula we get



Therefore the slope is 3.6 lbs per year.
