M=(y2-y1)/(x2-x1)
m=(-4-4)/(3-1)
m=-8/2
m=-4
so the answer should be first one
Answer:
38.13 m^2
Step-by-step explanation:
the area of a triangle =b*h/2
b=base
h=height
area triangle=(4m*3m)/2=(12m^2)/2=6m^2
the area of a rectangle =b*h
b=base
h=height
area of a rectangle=6m*3m=18m^2
area of a semi circle=(pi*r^2)/2
r=radius
area of a semi circle==(3.14*(3m)^2)/2=14.13m^2
area of the figure=6m^2+18m^2+14.13m^2=38.13m^2
the answer is 38.13m^2
Answer:
h.
Step-by-step explanation:
11 / 232 = 0.047
0.047 x 100% = 4.7%
Answer:
Algebraic expressions describe an algebraic operation. They can be as simple as a number, or they can include integer constants of numbers, variables, and symbols.
Step-by-step explanation:
The value of the integral 3ydx+2xdy using Green's theorem be - xy
The value of 
be -xy
<h3>What is Green's theorem?</h3>
Green's theorem relates a line integral around a simple closed curve C to a double integral over the plane region D bounded by C.
If M and N are functions of (x, y) defined on an open region containing D and having continuous partial derivatives there, then
= 
Using green's theorem, we have
= ............................... (1)
Here 
= differentiation of function N w.r.t. x
= differentiation of function M w.r.t. y
Given function is: 3ydx + 2xdy
On comparing with equation (1), we get
M = 3y, N = 2x
Now, = 
= 
= 2
and, = 
= 
= 3
Now using Green's theorem
= 
= 
= 
=
The value of be -xy.
