This is defined as a binary operation, the elementary arithmetic operation of subtraction. Other operations involving two real numbers are addition, multiplication, and division; in contract unary operations involve only one number and come in the form of trigonometric functions and negation, for example.
Answer:y=2x-5
Step-by-step explanation:
Answer:
height=100feet
Step-by-step explanation:
perimeter of a rectangle=p=500 feet
p=2a+2b equation 1
a=height
b=base
we have: b/a=3/2
so a=(2*b)/3
in equation 1 we have:
500=2*((2*b)/3)+2*b
so we have
500=(4*b)/3 + 2*b
500=(4b+6b)/3
500=(10b)/3
500*3=10b
b=(500*3)/10
b=150 feet =base
so
a=(2*150)/3=100 feet = height
Answer:
<u>a = 60° or π/3</u>
Step-by-step explanation:
<u>Given :-</u>
sin² a/2 - sin a/2 + 1/4
<u>To find :-</u>
a
<u>Solving :-</u>
sin² a/2 - sin a/2 + 1/4 = (sin a/2 - 1/2)² = 0
sin a/2 - 1/2 = 0
sin a/2 = 1/2
a/2 = 30°
<u>Solution :-</u>
<u>a = 60° or π/3</u>
