Answer:
∅ = 90°
Step-by-step explanation:
Given;
sin2∅=2sin∅
sin2∅ = 2sin∅Cos∅
but, Sin²∅ + Cos²∅ = 1
Cos²∅ = 1 - Sin²∅
Cos ∅ = √(1 - Sin²∅)
sin2∅=2sin∅ ↓
2sin∅Cos∅ = 2sin∅
2sin∅(√(1 - Sin²∅)) = 2sin∅
Let Sin∅ = P
2P( √(1 - P²)) = 2P
Divide both sides by 2P
√(1 - P²) = 1
Square both sides
1 - P² = 1
P² = 1 - 1
P² = 0
P = 0
Recall, Sin∅ = P
Sin∅ = 0
∅ = Sin ⁻¹(0)
∅ = 90°
Answer:
−16(2−−5)
Step-by-step explanation:
hay un factor común entre estos números, por lo que simplemente −16t2+16t+80 divida y reutilice y luego reciba−162+16+80 llegar
−16(2−−5)

Answer:
y=1/3x-2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(6-0)
m=(0+2)/6
m=2/6
simplify
m=1/3
y-y1=m(x-x1)
y-(-2)=1/3(x-0)
y+2=1/3(x)
y+2=1/3x
y=1/3x-2
Answer:
the range is {-2, 6, 22}
Step-by-step explanation:
Use " ^ " to indicate exponentiation: f(x) = x^2 - 3.
For each value in the domain {1, 3, 5}, calculate f(x) = x^2 - 3:
f(1) = 1^2 - 3 = -2
f(3) = 3^2 - 3 = 9 - 3 = 6
f(5) = 5^2 - 3 = 25 - 3 = 22
Thus, the range is {-2, 6, 22}
