Answer:
The demand equation is: D=-4p+23
Step-by-step explanation:
To get started, we should keep in mind that the market price (p=3) occurs when supply equals demand ,therefore when p=3
S=2(3)+5=11
Thus, when p=3 D=11 and, according to the problem when p=1 D=19.
We already know two points on the demand curve. Great!
The demand equation is linear, so it has form D=bp+c.
The variable b is the slope of the demand linear equation . It can be computed through the formula
. equation 1
Substituting the two points (3,11) and (1,19) on equation 1.
b=-4
Now we can find the value of intercept of the demand equation c trough point-slope form y-y1=b(x-x1).
We can use any of the points. Let's take (3,11) and write in point-slope :
y-11=-4(x-3)
y=-4x+11+12
y=-4x+23
Rewrite the linear equation according our variables D and p
D=-4P+23
Finally we found the demand equation !
Answer:
Option C.
Step-by-step explanation:
we know that
The surface area of the triangular prism using the net is equal to the area of two triangles plus the area of three rectangles
so
It is clearly understood from the image that LPNM is a square.
Let the side of the square be 'a' units.
Then by Pythagorean theorem.
Now taking square root on both side we get ;
Now pluging the value of C in the above equation we get ;
Therefore LP = 6√2 units.
