The first term of a progression is 5x and the second term is x^2
a. For the case where the progression is arithmetic with a common difference of 14
i. show that x^2 - 5x - 14 = 0
ii. find the possible values of x and the corresponding values of the third term
b. For the case where the progression is geometric with a sum to infinity of 10
i. explain why x cannot be equal to zero
ii. show that 5x/1-x/5 = 10
iii. find the third term

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 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.
