The quotient rule is
d(u/v) = (u dv - v du) / u2
d(u/v) can written as
d( u (1/v) )
Using the product rule and chain rule
d( u (1/v)) = u d(1/v) + (1/v) du
= u (-1/v2) dv + (!/v) du
= (u dv - v du) / u2
Answer:
Aliyah will take a total of 4274 steps.
Step-by-step explanation:
Given:
Number of steps from home to store = 1317 steps
Number of steps from store to park = 561 steps
Number of steps from park to friends house = 259 steps
So now we will find the Total number of steps from home to friends house.
Total number of steps from home to friends house can be calculated by adding Number of steps from home to store and Number of steps from store to park and Number of steps from park to friends house.
framing in equation form we get;
Total number of steps from home to friends house = 
Is same route is followed to home we can say that;
Total number of steps from friends house to home = 2137 steps.
So Total number of steps she will take next day will be equal to Total number of steps from home to friends house plus Total number of steps from friends house to home.
framing in equation form we get;
Total number of steps she will take next day = 2137 +2137 = 4274 steps
Hence Aliyah will take a total of 4274 steps.
Answer: Observational study
Step-by-step explanation: I just took the test
To evaluate this expression, we need to remember that subtracting a negative number is the same as adding a positive number, and that adding a negative number is the same as subtracting a positive number. Using this knowledge, let's begin to simplify the expression below:
-1 - 3 - (-9) + (-5)
Because addition of a negative number is the same as subtraction of a positive number, we can change + (-5) to -5, as shown below:
-1 - 3 - (-9) - 5
Next, because we know that subtracting a negative number is the same as adding a positive number, we can change - (-9) to + 9, as shown below:
-1 - 3 + 9 - 5
Now, we can subtract the first two terms and begin to evaluate our expression:
-4 + 9 - 5
Next, we can add the first two numbers of the expression:
5 - 5
Now, we can subtract our last two numbers, which gives us our answer:
0
Therefore, your answer is 0.
Hope this helps!
