At 45° latitude, the gravitational acceleration as a func- tion of elevation z above sea level is given by g = a - bz, 3.32x 10-6 s-2. determine object will 1-8 nhill con- 9.807 m/s2 and b where a the height above sea level where the weight of an decrease by 0.3 percent. peri- 8862 m its.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
