Independent variable is the height and dependent variable is weight so you will have a quadratic such as weight = number•height^2 + number•height + number. All you need is to figure out first number and second number and third number (usually denoted by a,b,c) it will be a very tedious calculation by hand which deals with sum of the weight, sum of the weight squared, sum of weight•weight, number of weights, and sum of heights etc etc with the same pattern. It should be done by a calculator. At the end the Weight = a height^2 + b height + c (with a b c results displayed on the calculator) and then Answer = a*5.8^2 + b*5.8 + c
-b - 3b = -16 -2b
Put -b and -3b together
-4b = -16 -2b
Add 2b to both sides
-2b=-16
Divide by -2
b=8
I think that is the second one but I’m not really sure , sorry if isn’t correct
Answer:
5% Discount: $14,968.42
7% Discount: $12,099.56
Step-by-step explanation:
Since the discount rate is being compounded annually we can go ahead and use the Exponential Growth Formula, or in this case we will actually be using the Exponential Decay Formula since we are compounding a discount rate

Where:
- D is the present value
- a is the initial cash flow
- r is the discount rate in decimal form
- t is the span of time
Since we are looking for the present value in 10 years with a rate of 5%, we can plug these values into the formula and solve for D.




So the Present day value at 5% discount rate is $14,968.42 .
Now we can solve the equation at a 7% discount rate.




So the Present day value at 7% discount rate is $12,099.56
