The concept that can be used in order to answer this item is that of man-days. The total number of man-days required to do the job should always be constant.

This can be illustrated by the givens above.
Scenario 1:
N1 = (4 employees)(4 days) = 16 man-days

Scenario 2:
N2 = (2 employees)(8 days) = 16 man-days

The equation for determining the value of e is equal to,
k = (d)(e)

The answer is the second choice.

Answer: inverse variation; $de = k$

Step-by-step explanation:

Given: In a company, it takes 4 employees 4 days to complete a task.

Work done by complete the task by = $4\times4=16$

Similarly, It would take 2 employees 8 days to complete the same task.

Work done by complete the task = $2\times8=16$

There is inverse variation which means if number of workers decreases then the number of days increases.

If e represents the number of employees working on the task and d represents the number of days it takes them to complete that task.

Then, by inverse variation $de = k$

The correct answer is A.

That is because the whole paragraph talks about a model car that they are testing but this student is wondering about roller coasters.

Hope this helps :)

Week 1 2 3 4 5 Water Level (inches) − 1 1 4 1 3 8 2 1 2 − 1 5 8 − 1 3 4 Between which two weeks did the water level change the m

Answer:

The water level change the most in week 3 and week 4

The change = -370 inches

Step-by-step explanation:

Given - Week 1 2 3 4 5

Water Level (inches) − 1 1 4 1 3 8 2 1 2 -1 5 8 -1 3 4

To find - Between which two weeks did the water level change the most? Calculate the change .

Proof -

The formula for change in water level with respect to week be-

Rate of Change in Water Level = Difference in water level / Difference in weeks

Now,

For week 1 and week 2

Rate of change in water level = $\frac{138 - 114}{2 - 1}$ = $\frac{24}{1}$ = 24 inches

Now,

For week 1 and week 3

Rate of change in water level = $\frac{212 - 114}{3 - 1}$ = $\frac{98}{2}$ = 49 inches

Now,

For week 1 and week 4

Rate of change in water level = $\frac{-158 - 114}{4 - 1}$ = $-\frac{272}{3}$ = -90.67 inches

Now,

For week 1 and week 5

Rate of change in water level = $\frac{-134 - 114}{5 - 1}$ = $-\frac{248}{4}$ = -62 inches

Now,

For week 2 and week 3

Rate of change in water level = $\frac{212 - 138}{3 - 2}$ = $\frac{74}{1}$ = 74 inches

Now,

For week 2 and week 4

Rate of change in water level = $\frac{-158 - 138}{4 - 2}$ = $-\frac{296}{2}$ = -148 inches

Now,

For week 2 and week 5

Rate of change in water level = $\frac{-134 - 138}{5 - 2}$ = $-\frac{272}{3}$ = -90.67 inches

Now,

For week 3 and week 4

Rate of change in water level = $\frac{-158 - 212}{4 - 3}$ = $-\frac{370}{1}$ = -370 inches

Now,

For week 3 and week 5

Rate of change in water level = $\frac{-134 - 212}{5 - 3}$ = $-\frac{346}{2}$ = 173 inches

Now,

For week 4 and week 5

Rate of change in water level = $\frac{-134 + 158}{5 - 4}$ = $\frac{24}{1}$ = 24 inches

∴ we get

The water level change the most in week 3 and week 4

The change = -370 inches

Note :

The highest change means which temperature goes the most change in water level. It can be negative also.

So, We have to take the modulus and then find the highest number.

Here, 370 > 173

So, Highest change occurs in Week 3 and Week 4 but not in Week 3 and Week 5.

Why does my sister hate me?

Nata [24]

Answer:

Sister Are Like That Sometimes, Give her Time!

Step-by-step explanation:

Bigger siblings- especially girls- love their private time. If your sister seems annoyed, I suggest you just walk away. If she gets upset, agree with her argument. As a bigger sister myself, sometimes we just want nothing more than to be alone. Have you told your parents about this? Siblings need a reminder that they aren't always in charge. Tell your sister that you appreciate her, and that if she ever needs help going through anything, you're there for her. I understand this isn't the easiest, but that's how you can better connect with her.
