Aaron and noah wanted to have a contest to see which of their paper airplanes could fly the longest distance. Aaron's plane flew
Marina CMI [18]

Aaron's plane flew 3.21 meters further than Noah's plane.

<u><em>Explanation</em></u>

Aaron's plane flew 4 meters and Noah's plane flew 79 centimeters.

So, first we need to <u>convert 79 centimeters into meters</u>.

We know that, 1 centimeter = 0.01 meter

So, 79 centimeters = (0.01*79)meter= 0.79 meter

Now, the difference of distance between Aaron's plane and Noah's plane is (4-0.79) meters = 3.21 meters

Stella [2.4K]

Answer:

see the procedure

Step-by-step explanation:

Looking at the graph we have

The graph represent a  vertical parabola open upward

The vertex is a minimum

The vertex is the point (-4,-3)

The domain is the interval -----> (-∞,∞)

The Domain is all real numbers

The range is the interval ----> [-3,∞)

y\geq -3

The range is all real numbers greater than or equal to -3

The graph is increasing in the interval (-4,∞)

The graph is decreasing in the interval (-∞,-4)

The minimum of the graph is y=-3 occurs at x=-4

From the top of a cliff 426 feet high, the angle of depression of a ship is observed to be 18.2°. how far out is the ship? 140 f
lara [203]
If we are to connect both tips of the cliff to the approaching ship, we form a right triangle. The height of the cliff is the opposite side of the angle of depression. The trigonometric function that would allow us to solve for the distance is tangent.
                    tan 18.2° = opposite /adjacent = 426 ft/ x ft
The value of x from the equation is 1295.68 ft
Thus, the answer is the second choice.
