Tofind:The standard form of the equation of sphere with endpoints of the diameter as

Answer to Problem 62E
The standard form of the equation of sphere with endpoints of the diameter as
Explanation of Solution
Given information:
The vertices of endpoints of a diameter are
Calculation:
The general standard form of the equation of sphere is
The center of the sphere is the midpoint of the vertices of endpoints of diameter.
Use the formula for midpoint.
Substitute
So, the center of the sphere is
Use the distance formula for the length of diameter.
Substitute
So, the length of the diameter is
The radius of sphere is half the length of the diameter.
Substitute
Therefore, the standard form of the equation of sphere with endpoints of a diameter as

The first earns 10% compounded annually, the second earns 10% compounded quarterly, and the third earns 10% compounded continuously. Find equations that model each investment growth and use a graphing utility to graph each model in the same viewing window over a 20-year period. Use the graph to determine which investment yields the highest return after 20 years. What are the differences in earnings among the three investment? STEP 1: The formula for compound interest is A = nt = P(1 + − − ) n², where n is the number of compoundings per year, t is the number of years, r is the interest rate, P is the principal, and A is the amount (balance) after t years. For continuous compounding, the formula reduces to A = Pert Find r and n for each model, and use these values to write A in terms of t for each case. Annual Model r=0.10 A = Y(t) = 1150 (1.10)* n = 1 Quarterly Model r = 0.10 n = 4 A = Q(t) = 1150(1.025) 4t Continuous Model r=0.10 A = C(t) =…arrow_forwardUse a graphing utility to find the point of intersection, if any, of the graphs of the functions.
