B. Open the compass to a quarter of the length of AB¯¯¯¯¯¯¯¯ and draw a long arc through point A.
C. Put the compass point on point A and draw a long arc. Be sure the opening is less than half of the length of AB¯¯¯¯¯¯¯¯.

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.
