From my notes I’ve the derivative of arctan(x)= 1/(1+x^2)
Answer:
Answer as a fraction: 4/15
Answer as a decimal: 0.267
The decimal version is approximate rounded to three decimal places.
Step-by-step explanation:
6 apples, 4 peaches
6+4 = 10 pieces of fruit total
The probability of picking an apple is 6/10 = 3/5
After you pick and eat the apple, there are 10-1 = 9 pieces of fruit left. Also, the probability of picking a peach is 4/9, as there are 4 peaches out of 9 fruit left over.
Multiply out 3/5 and 4/9 to get (3/5)*(4/9) = (3*4)/(5*9) = 12/45 = 4/15
Using a calculator, 4/15 = 0.267 approximately.
Answer:
times it by 3 on both sides should get 180
Step-by-step explanation:
Number of difference arrangements = 5! = 5 x 4 x 3 x 2 x 1 = 120
Answer: There are 120 different arrangements.

Step-by-step explanation:
1 km = 1,000 m = 100,000 cm = 1,000,000 mm
1 mm is millionth part of 1 km
1 mm = 0.000001 km
20 mm = 0.00002 km
