There always exists a real number n such that a^n = b^n + c^n , where a, b and c are any integers. The problem is not Fermat's Last Theorem, but a variation of it with real exponents.

If a baseball is projected upward from ground level with an initial velocity of 64 feet per second, then its height is a function of time, given by s(t) = -16t squared + 64t. How would I graph this function for 0 ≤ t ≤ 4? And how do I determine the maximum height reached by the ball?
1. Given the quadratic equation y=-x2 + 8x + 9 a. Find the x and y coordinates of the vertex b. What is the y-intercept? c. What are the x-intercepts? d.

In the real world, what might be a situation where it is preferable for the data to form a relation but not a function? If the variables in an equation were reversed, what would happen to the graph of the equation? For example, how would the graph of y = x² relate to the graph of x = y²?
Any help is greatly appreciated; I found this problem pretty frustrating. I replaced the "less than" symbol with the words "less than" because the computer seemed to have a hard time recognizing the symbol. "For a fish swimming at a speed v relative to the water, the energy expenditure per unit time is proportional to v^3.
7.4.2 Show that the following family is not complete by finding at least one nonzero function u(x) such that E[u(X)]=0, for all theta >0. f(x; theta)= 1/(2*theta), -theta <x< theta where 0<theta<infinity and 0 elsewhere. The answer is Xbar.

Find a linear function perpendicular to the function y= -5x + 12 at the point (2,5) in standard form, point slope form, and slope-intercept form. The orginal line is y = -5x + 12 (slope is -5), so the perpindicular line will be y = 1/5x + ? 5 = (1/5)2 + ?.
