Answer:
The rate of change of the distance between the cars at that instant is 5.46 meters per second
Step-by-step explanation:
Speed of first car = 7 m/s
Speed of second car = 3 m/s
At instant, distance of first car from intersection = 5 meters
distance of second car from intersection = 12 meters
Therefore, we have
Distance between both cars at intant = √(12² + 5²) = 13 m
Rate of cahnge of distance is given by;
2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt
= 26dd/dt = 2×5×7 + 2×12×3 = 142
dd/dt = 142/26 = 5.46 m/s.
That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.
Is there a graph for the problem?
Answer:
Step-by-step explanation:
Given Rule: Multiply by 3, add -2
Input:
10, 17, 25, 27
Carry out the rule:
10(3) + (-2) = 30 - 2 = 28
17(3) + (-2) = 51 - 2 = 49
25(3) + (-2) = 75 - 2 = 73
27(3) + (-2) = 81 - 2 = 79
The outputs are 28, 49, 73, and 79 respectively.
Let me know if you have any questions!
To answer this all we need to do is DIVIDE.
98515 ÷ 85 = <span>1159
CHECK OUR WORK
1159 </span>× 85 = 98515
<span>
So, we were right!! :)
So, there would be 1159 trees on each acre.
Hope I helped ya!!
