Answer:
Step-by-step explanation:
<u>The filling speed is 30 hours or:</u>
<u>The draining speed is 34 hours or: </u>
<u>If both lines are open simultaneously, the filling speed is:</u>
- 1/30 - 1/34 =
- 17/510 - 15/ 510 =
- 2/510 =
- 1/255 in an hour
<u>If the tank is 1/5 full, then we need to fill the 4/5 of level and it will take:</u>
- 4/5 : 1/255 =
- 4/5 *255 =
- 204 hours
Answer:
n^6-m
Step-by-step explanation:
ACCORDING TO QUEDTION 1 ST NO IS N
AND 2 ND NO. IS M
N RAISED TO POWER 6=N^6
AND THE M SUBTRACTED FROM N^6=N^6 -M

Answer:
It is a linear function.
Step-by-step explanation:
The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.
To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).
This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.
Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2). Slope intercept is y=mx+b.
The line of the equation would then be y = -2/3x -2
