Given:
45°- 45°- 90°
one leg is equal to 2
Work:
The rules for a 45°- 45°- 90° state that both leg are equal to eachother and because of this the hypotenuse is equivalent to x√2. Because of this, we know that the other leg is equivalent to 2, and that since 2 = x, the hypotenuse is 2√2.
Sine = o/h (opposite/hypotenuse)
o = 2
h = 2√2
sinθ = 2/(2√2) --> (2√2)/4 --> √2/2
Tangent = o/a (opposite/adjacent
o = 2
a = 2
tanθ = 2/2 --> 1
Answer:
sinθ = √2/2
tanθ= 1
I hope this helps!
Answer:
f^−1(x)=1/3+lnverse(x)/3inverse(2)
Step-by-step explanation:
Answer:
Sophie factored completely.
Carlos did not factor out a 2 out of his last term
Step-by-step explanation:
-4x² − 10x + 6
Sophie factored it as -2(2x − 1)(x + 3) and Carlos factored it as (x + 3)( -4x + 2).
If you look at the last term in Carlos
(x + 3)( -4x + 2)
You can factor out a -2
(x+3) (-2)(2x-1)
It is not factored completely with the negative two inside the parentheses
He could also have factored out a 2
(x+3) (2)(-2x+1)
I like having a positive x so I use the -2
Either would be acceptable.
