Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
Answer:
n is a neutron , the symbol n stands for neutron
Answer:
Step-by-step explanation:
y = -7/8x - 10
in y = mx + b form, which is what this is in, the slope can be found in the m position
y = mx + b
y = -7/8x - 10
so u have slope (m) = - 7/8 <====
the slope is not 10
the graph will not pass thru the origin
this equation does not represent a proportional relationship
Answer:
-50
Step-by-step explanation:
b-5 
b-5 = -45 ( collect like terms)
b = -45 + -5
b = -45 -5 b = -50
