Question:
Jordan is cutting a 2 meter by 
meter piece of rectangular paper into two pieces along its diagonal. what is the area of each of the pieces?
Answer:
Area of each piece of paper is 
.
Solution:
Length of the paper = 2 m
Width of the paper = m = 
m
<em>Area of the rectangle = length × width</em>
<em>Diagonal of a rectangle divides it into two equal parts.</em>
Area of each piece = Area of the rectangle ÷ 2
Area of each piece of paper is .
Answer:
y=3x+2
Step-by-step explanation:
True
As it is said in the question the probability of getting a head is 0.5. And, if we toss it two times it will be 0.25.
We'll have to multiply 0.5 with 0.5.
The answers are:
1. c = 31.4
2. 96.2
LHS ⇒ RHS:
Identities:
[1] cos(2A) = 2cos²(A) - 1 = 1 - 2sin²(A)
[2] sin(2A) = 2sin(A)cos(A)
[3] sin(A + B) = sin(A)cos(B) + cos(A)sin(B)
[4] cos(A + B) = cos(A)cos(B) - sin(A)sin(B)
cos(x) - cos(x + 2Θ)
= cos(x) - (cos(x)cos(2Θ) - sin(x)sin(2Θ)) [4]
= cos(x) - cos(x)(1 - 2sin²(Θ)) + sin(x)(2sin(Θ)cos(Θ)) [1] [2]
= cos(x) - cos(x) + 2sin²(Θ)cos(x) + 2sin(Θ)sin(x)cos(Θ)
= 2sin²(Θ)cos(x) + 2sin(Θ)sin(x)cos(Θ)
= 2sin(Θ)(sin(Θ)cos(x) + sin(x)cos(Θ))
= 2sin(Θ)sin(x + Θ)
