Answer:
Step-by-step explanation:
(−2x + 6y)(4x − 6y)
To multiply this we use FOIL method
first we multiply -2x with 4x, it becomes -8x^2
Then multiply -2x with -6y, we get 12xy
multiply 6y with 4x, we get 24xy
multiply +6y with -6y, we get -36y^2
Now we commbine all the answers we got
combien like terms
12xy+24xy= 36xy
cb^2 + ab^2 = ca^2 pythagorean theorem
cb^2 +6^2 = 12^2
cb^2 +36 = 144
cb^2 = 108
cb = sqrt (108)
sin D = opp /hyp
sin D =bc/cd
sin 55 = sqrt(108)/cd
cd = sqrt(108)/sin 55
cd=12.687
cd = 12.7 to three significant figures
Answer:
increases
in general, greater consumption of a good brings higher total utility.
Answer: The number π is a mathematical constant, approximately equal to 3.14159. It is defined in Euclidean geometry as the ratio of a circle's circumference to its diameter, and also has various equivalent definitions. The number appears in many formulas in all areas of mathematics and physics.
Also yes, it does have a symbol: π
