Answer:
dy/dx = -1/
Step-by-step explanation:
y = 1/x
dy/dx = d/dx(1/x)
=> dy/dx = d/dx()
=> dy/dx = -
=> dy/dx = -1/

Answer:
The Area of the composite figure would be 76.26 in^2
Step-by-step explanation:
<u>According to the Figure Given:</u>
Total Horizontal Distance = 14 in
Length = 6 in
<u>To Find :</u>
The Area of the composite figure
<u>Solution:</u>
Firstly we need to find the area of Rectangular part.
So We know that,
Here, Length is 6 in but the breadth is unknown.
To Find out the breadth, we’ll use this formula:
According to the Figure, we can see one side of a rectangle and radius of the circle are common, hence,
- Since Length = 6 in ;
Hence Radius is 6 in.
So Substitute the value of Total distance and Radius:
- Total Horizontal Distance= 14
- Radius = 6
Hence, the Breadth is 8 in.
Then, Substitute the values of Length and Breadth in the formula of Rectangle :
- Length = 6
- Breadth = 8
Then, We need to find the area of Quarter circle :
We know that,
Now Substitute their values:
- r = radius = 6
- π = 3.14
Solve it.
Now we can Find out the total Area of composite figure:
We know that,
So Substitute their values:
= 48
= 28.26
Solve it.
Hence, the area of the composite figure would be 76.26 in² or 76.26 sq. in.
I hope this helps!
Answer:
80 pages
Step-by-step explanation:
Given:
Number of pages printed = 5493
Number of booklets made = 68
Let each booklet use 'x' pages.
So, pages used by 68 booklets is given by unitary method and is equal to:
Now, total number of pages are 5493.
Therefore, the pages used by the 68 booklets should be less than or equal to the total number of pages available. So,
Therefore, the number of pages in each booklet is 80.
