Answer:
24 ft²
6 × 3 + (½ × 4 × 3)
Step-by-step explanation:
Split shape into a rectangle and triangle;
The rectangle is 6 by 3 ft, the area can be found by multiplying the 2 dimensions:
6 × 3 = 18
The triangle has base 4 ft, the total length of the shape (10 ft) take the 6 ft that is part of the rectangle;
The height is 3 ft;
The area us found by ½ × base × height:
½ × 4 × 3 = 6
Add this together to get the total area.
Answer:

Step-by-step explanation:
You have the following differential equation:

This equation can be written as:

where

If the differential equation is exact, it is necessary the following:

Then, you evaluate the partial derivatives:

The partial derivatives are equal, then, the differential equation is exact.
In order to obtain the solution of the equation you first integrate M or N:
(1)
Next, you derive the last equation respect to t:

however, the last derivative must be equal to M. From there you can calculate g(t):
![\frac{\partial F(t,y)}{\partial t}=M=(7y-3t)e^t=7ye^t+g'(t)\\\\g'(t)=-3te^t\\\\g(t)=-3\int te^tdt=-3[te^t-\int e^tdt]=-3[te^t-e^t]](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpartial%20F%28t%2Cy%29%7D%7B%5Cpartial%20t%7D%3DM%3D%287y-3t%29e%5Et%3D7ye%5Et%2Bg%27%28t%29%5C%5C%5C%5Cg%27%28t%29%3D-3te%5Et%5C%5C%5C%5Cg%28t%29%3D-3%5Cint%20te%5Etdt%3D-3%5Bte%5Et-%5Cint%20e%5Etdt%5D%3D-3%5Bte%5Et-e%5Et%5D)
Hence, by replacing g(t) in the expression (1) for F(t,y) you obtain:

where C is the constant of integration
Answer:
Range is number of copies produced and set of values is; 1 ≤ N ≤ 200
Domain; Cost of publishing book in dollars; set of values are; $710 ≤ N ≤ $2700
Step-by-step explanation:
Range is a set of all the possible output values in a function while domain is the set of all possible input values.
Now, the function is given as;
C = 10N + 700
Where;
C is the cost of publishing the book in dollars
N is the number of copies of books produced
Thus, the domain will be a set of N values while Range will be a set of C values.
We are told that the first printing can produce up to 200 copies of the book.
That means a maximum of 200 books and a minimum of 1.
Thus;
Range is; 1 ≤ N ≤ 200
Maximum possible cost of the 200 books is;
C = 10(200) + 700
C = $2700
Minimum cost which will be for 1 book will be;
C = 10(1) + 700
C = $710
Thus,domain is;
$710 ≤ N ≤ $2700
We could write such a number as



so we're done.
