+ has a cylinder 22 feet tall.

(Diagram is not drawn to scale)

a) Calculate the volume of one grain bin. Show your work.

b) Mr. Mernard would like to paint the exterior (top and sides) of the bins

+ each bin needs 2 coats of paint.

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.

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9

Write the expression as a single natural logarithm. 2 in a - 4 in y
