or, 
Answer:
ANSWER C
Step-by-step explanation:
y = x²
y = -x² reflect across the x axis
y = -(x + 2)² shift 2 units to the left
y = -(x + 2)² + 5 shift up 5 units
Answer:
A. Cos θ = 16/42
Step-by-step explanation:
The angle the ladder makes with the floor = θ
Hypotenuse = length of the ladder = 42 m
Adjacent = Distance from the bottom of the ladder to the wall = 16 m
Therefore to find θ, we would apply the trigonometric function, CAH:
Cos θ = adj/hyp
Which is:
Cos θ = 16/42
