Start with y = 2x. Subst. a for x and a+sqrt(3) for y:
a+sqrt(3) = 2a
Subtracting a from both sides: sqrt(3) = a
Answer:
3√3
Step-by-step explanation:
If sinx = 4/8, find Cos (6x)
we need to first find cos
but applying trigonometry rule
sin²x+cos²x = 1
sinx = 4/8
sin²x = (4/8)² = 4²/8² = 16/64
from the rule
cos²x= 1 -sin²x = 1-16/64 = 64-16/64 = 48/64 = 3/4
cos²x = 3/4
cos x = √3/4 = √3/2
cos 6x = 6 x √3/2 = 3√3
The value exponential is 18
If you let x be the number to get 8 more you add so it would be x+8
First, you add up the non-$10 winning cars so 100+25=125.
then you take 5:125 because you want the winning 10$ against not winning. the to get 1 you divide both numbert by 5 to get 1 on the left. so you get 1:25.
hope i helped:)
