Answer:
length of a single chain link = 5.33 cm
Step-by-step explanation:
Given data: chain contained 1000 chain links
total length was 0.0533km
<em>1km = 1000m </em>
<em> 1m = 100cm therefore 1km = 100000cm</em>
<em />
total length in cm = 0.0533* 100000
total length in cm = 5330 cm
length of a single chain link = 5330/1000
length of a single chain link = 5.33 cm
Answer: Zero
Step-by-step explanation:
If you calculate -3 + 3 you get the answer of zero. Not sure if there is more to the problem.
Answer:
domain = {x|xER}
range = {y|y≥0,yER}
Step-by-step explanation:
|x| means the absolute value which in this case is the distance from 0. On a graph this function would look like a v and would mean it would have infinite x-values since it is opening upwards in both directions.
For the range the vertex of this function is (0,0), if the x-coordinate were 0 the y-coordinate would be 0 because the absolute distance from 0 is 0. for another x-coordinate say -2 the absolute distance from 0 is 2 meaning the y-value is 0 since y=|x|, making the coordinate (-2,2) meaning the range is every y value must be above 0 since there is no way for the y-value to be negative
D= (LR_2)/(R_2+R_1)
<span>d(R_2+R_1)= LR_2 </span>
<span>d(R_2+R_1)/(R_2)= L </span>
<span>L= d(R_2+R_1)/(R_2) </span>
<span>The answer I obtained is the same answer as the third choice. </span>
<span>L= d(R_2+R_1)/(R_2) </span>
<span>L= (R_2+R_1)d/(R_2) </span>
<span>L= (R_2+R_1)(d)/(R_2) </span>
<span>L= ((R_2+R_1)(d))/(R_2)</span>
