Do this by converting to vertex form
y = 4x^2 + 16x - 2
y = 4 (x^2 + 4x - 0.5) completing the square on x^2 + 4x:-
y = 4[(x + 2)^2 - 4.5]
the axis of symmetry is x = -2
The side of the square is 5.9 cm
<u>Step-by-step explanation:</u>
Area of the circle = 56 square cm
Side of the square= x
Area = π(r x r)
56 = π (r x r)
√17.83 = r
r = 4.22 cm
Diameter = 8.44cm
The diameter is equal to the diagonal of the square.
8.44 = x√2
x = 8.44/√2
= 5.9 cm
The side of the square is 5.9 cm
Answer:
The distance Plane A traveled in 1 h is greater than the distance Plane B traveled in 1 h.
Step-by-step explanation:
The equation of the distance traveled by Plane A is

The plane B traveled 540 miles in 2 hours.
So in 1 hour, plane B traveled 540/2 = 270 miles:
How does the distance Plane A traveled in 1 hour compare to the distance Plane B traveled in 1 hour?
Plane A:
d(1) = 290*1 = 290
Plane A traveled 290 miles in 1 hour.
Plane B travaled 270 miles in 1 hour.
So the correct answer is:
The distance Plane A traveled in 1 h is greater than the distance Plane B traveled in 1 h.
