Answer:
√5/3.
Step-by-step explanation:
Using the identity sin^2 O + cos^ O = 1
sin^2 O = 1 - cos^2 O
sin^2 O = 1 - (2/3)^2
sin^2 O = 1 - 4/9
sin^2 O = 5/9
sin O = √(5/9)
sin O = √5/3.
Answer:
how many 2/3's are "in 1" means how many times 2/3 can be divided into 1. Anything divided into 1 is the inverse of what's divided into 1. So there are 1/ (2/3)s. That's = 3/2. 3/2 is one and a half. If you add 2/3 and half of 2/3, you get 3/3, which is 1. So it's right.

Answer:
D.
Step-by-step explanation:
we are given
we can use standard equation of hyperbola
where
center=(h,k)
center at origin
so, h=0 and k=0
vertex is
we can use formula
vertices: (h, k + a)
we get
we can plug k=0
now, we can plug these values
now, we are given it passes through
so, we have
we can plug these values and then we can solve for b
and we get
we can solve for b
and we get
now, we can plug these values
we can simplify it
and we get
For the number 2 is -14x+6
For the number 1 is (2,3)
and I hope you that helps you!!!
Answer:
x = 4
Step-by-step explanation:
(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.
(6x - 3)° = (2x + 13)°
6x - 2x = 13 + 3
4x = 16
x = 4
Substitute x for the angles.
(6x - 3)° = ?
(6*4 - 3)° = ?
(24 - 3)° = 21°
(2x + 13)° = ?
(2*4 + 13)° = ?
(8 + 13)° = 21°
