At a price of $3.20 per bushel, the supply of corn is 9,800 million bushels and the demand is 9,200 million bushels. At a price of $2.95 per bushel, the supply is 9,300 million bushels and the demand is 9,700 million bushels. Find a price–supply equation of the form p = mx + b. p is in dollars, and x is in million bushels.

Given the following function:
$f (x) = 1.01 e^{4 x} - 4.62 e^{3 x} - 3.11 e^{2 x} + 12.2 e^{x}$
a) Use three-digit rounding frithmetic, the assumption that $e^{1.53} = 4.62$ , and the fact that $e^{n x} = {(e^{x})}^{n}$ to evaluate $f (1.53)$
b) Redo the same calculation by first rewriting the equation using the polynomial factoring technique
c) Calculate the percentage relative errors in both part a) and b) to the true result $f (1.53) = - 7.60787$

a) Find the Maclaurin series for the function
$f (x) = \frac{1}{1} + x$
b) Use differentiation of power series and the result of part a) to find the Maclaurin series for the function
$g (x) = \frac{1}{(x + 1)^{2}}$
c) Use differentiation of power series and the result of part b) to find the Maclaurin series for the function
$h (x) = \frac{1}{(x + 1)^{3}}$
d) Find the sum of the series
$\sum_{n = 3}^{\infty} \frac{n (n - 1)}{2 n}$
This is a Taylor series problem, I understand parts a - c but I do not understand how to do part d where the answer is $\frac{7}{2}$

The purchase price of a home y (in $1000) can be approximated based on the annual income of the buyer $x_{1}$ (in $1000) and on the square footage of the home $x_{2} (in 100 f t^{2})$ according to $y = a x_{1} + b x_{2} + c$
The table gives the incomes of three buyers, the square footages of the home purchased, and the corresponding purchase prices of the home. a) Use the data to write a system of linear equations to solve for a, b, and c.
b) Use a graphing utility to find the reduced row-echelon form of the augmented matrix.
c) Write the model $y = a x_{1} + b x_{2} + c$
d) Predict the purchase price for a buyer who makes $100000 per year and wants a $2500 f t^{2}$ home.

Turning back to high school math can be essential to understand engineering tasks that you may encounter later. The high school math problems have all the basics that have good equations and answers, which will let you see things clearly. The list of high school math questions below will help you identify your weaknesses and find various solutions. Taking a look at high school math equations, you will see certain parts that can be applied to Physics. In either case, the best way is to learn by example, which is why high school math problems with answers will be essential.
