Solve the following equation algebraically: - 16 = 16 x^2
How many solutions does this equation have? Explain.
a. -1 = x^2; One solution because only -1 will satisfy the equation.
b. -1 = x^2; No real solution because there is no real number that, when squared, produces -1.
c. 1 = x^2; Two solutions because the square root of 1 is positive 1 and negative 1.
d. 1 = -x^2; One solution because only -1 will satisfy the equation.

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 104 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 105 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
