Answer:
- -2/a³ m/s
- -2 m/s
- -1/4 m/s
- -2/27 m/s
Step-by-step explanation:
The velocity is the derivative of position:
v = ds/dt = (d/dt)(t^-2) = -2t^-3
For t=a, the velocity is
-2a^-3 = -2/a³ . . . . meters per second
For t=1, the velocity is ...
-2·1³ = -2 . . . . meters per second
For t=2, the velocity is ...
-2·2^-3 = -2/8 = -1/4 . . . . meters per second
For t=3, the velocity is ...
-2·3^-3 = -2/27 . . . . meters per second
Answer: 1.25
explanation: you multiply the amount of fabric used for one by the amount of potholders
.125 x 10 = 1.25
<u><em>Answer:</em></u>
24.2%
<u><em>Explanation:</em></u>
<u>The percentage of people choosing strawberry can be calculated as follows:</u>

<u>We have:</u>
Number of people choosing strawberry = 15 people
Total number of surveyed people = 17 + 10 + 17 + 3 + 15 = 62 people
<u>Substitute in the above rule to get the percentage as follows:</u>
%
