Para redondear este número a 1,000, verifiquemos el tercer dígito del número.
Si el dígito es mayor que 5, aumentamos el siguiente número en 1 unidad.
Si el dígito es menor o igual a 5, mantenemos el siguiente número.
El tercer dígito es 3, por lo que el número redondeado es:
Answer:
-sqrt(3)/2
Step-by-step explanation:
Use double angle identity for sin(2x)
sin(2x)=2sin(x)cos(x)
We are given sin(x)=-1/2 so we already have so far that:
sin(2x)=2(-1/2)cos(x)
sin(2x)=-1*cos(x)
We just need to find cos(x).
x is in the fourth quadrant so cosine will be positive there
knowing the unit circle we should know that if sin(x)=-1/2 then cos(x)=sqrt(3)/2 while in 4th quadrant.
So the answer is sin(2x)=-1*sqrt(3)/2=-sqrt(3)/2
Answer: angle A=40, Angle B=74, Angle C=66
Step-by-step explanation:
We all know that a triangle has 180 degrees.
3x-8+5x-6+4x+2=180
12x-12=180
12x=180+12
12x=192
x=16.
∠A=2(16)+8=40
∠B= 90-16=74
∠C = 5(16) -14= 66

Answer:
151200 ways
Step-by-step explanation:
Well assuming the numbers go from 0 to 9
we have
_ _ _ _ _ _ six spaces
in the first one can go one of the ten so the first one has 10 options
10*_ _ _ _ _
the second one has 9 options because we have used one alredy
and so on
10*9*8*7*6*5=151200
