As an object or substance gets colder, its molecules slow down. Theoretically, the lowest temperature an object can reach is called absolute zero. That's about -460°F, or -273°C. At absolute zero, all molecular motion in an object would freeze to a halt, and the object would contain no heat energy. It is physically impossible to reach absolute zero, but scientists have gotten very close to it with the help of special refrigeration devices and techniques. What is absolute zero? A the temperature at which water freezes B the lowest temperature ever reached on Earth C the highest temperature an object or substance can reach before boiling D the temperature an object would be if its molecules were completely still BACK

the answer to this question is 3/19

step-by-step explanation:

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

exactly you go it

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
