Answer:
h(1) = 1
h(4) = 5
Step-by-step explanation:
Since 1 is in the interval 1 ≤ x ≤ 3, you must substitute 1 into the expression 
So, h(1) =
= 1
Since 4 is in the interval x > 3, and all values of x > 3 gives an output of 5, then h(4) = 5
The answer is 456
This the answer 456
Answer:
30 degrees
Step-by-step explanation:
To figure out theta is using a bit of simple trigonometry.
2sin(theta) = 1
= sin(theta) = 0.5
Using arcsin (sin^-1) we can isolate x
x = arcsin(0.5)
x = 30

Answer:
EF =
≈ 5.83
Step-by-step explanation:
Calculate EF using the distance formula
d = 
with (x₁, y₁ ) = E(1, 3) and (x₂, y₂ ) = F(- 2, 8)
EF = 
= 
= 
=
≈ 5.83 ( to 2 dec. places )
