Answer:
Step-by-step explanation:
If I'm understanding this correctly, your problem is as follows:
The area of a circle is given by the formula
The area of the circle is changing at a rate of . Find the rate of change of the radius, , when r = 8.
Assuming that is what you are asking, we will begin by finding the derivative of the area of a circle using implicit differentiation.
Filling in what we have:
which simplifies a bit to
Divide both sides by 16π to get:
The π's cancel leaving the rate of change of the radius as
inches per second
13.5
15
14
Let's use the line on the right side. In the smaller triangle, the length is 4. The same side on the bigger triangle is 12. The ratio of the smaller triangle to the bigger triangle is:
To find a side length for the bigger triangle, all you need to do is multiply by 3. The same side on the smaller triangle is 5. Multiply by 3
That means x = 15
Answer: 6.413
Step-by-step explanation:
What is 10 - 3.587?
This is subtraction of decimals. To subtract decimals, you can follow these steps:
• Write down the numbers given with the bigger number on top of the lower number.
• Add zeros after the decimals so the numbers will both have same length.
• Then subtract.
Therefore, 10 - 3.587 will be:
= 10.000 - 3.587
= 6.413

Below is an attachment containing the solution
Answer: She would multiply the rate by the years to find the average rise in water levels, or 1.8 times 6.2 = 11.16. To find the difference between the water levels, she would subtract -13.64 from 11.16.

Step-by-step explanation:
We are asked to find out the first three terms of the sequence.
Recurring formula is given as
Since I term = 3
Applying the same rule,
third term
=
Like this we can find out any number of terms using this recursive formula
