When waiting to land, an airplane is traveling above the airport in a holding pattern that can be modeled by the equation 49x2 +

Fiesta28 [93]

49x^2 + 64y^2 = 3136 . . . (1)
y - 6 = (1/4)x^2 . . . (2)

From (2), x^2 = 4(y - 6) = 4y - 24 . . . (3)

Putting (3) into (1) gives
49(4y - 24) + 64y^2 = 3136
196y - 1176 + 64y^2 = 3136
64y^2 + 196y - 4312 = 0
y = 6.819
x = sqrt(4(6.819) - 24)
x = 1.81

The possible point of collision is (1.81, 6.819)

is it possible draw a right triangle with and obtuse angle? if so draw it in the box if not write impossible. is it possible guy

Ipatiy [6.2K]

It is not possible. Since one of the angles has to be a right angle, the other two angles would have to add to 90. Therefore, neither of these angles can be more than 90 degrees.

Hope this helps

The perimeter of a rectangle garden is 48 feet. The length is 5 times the width.

VARVARA [1.3K]

I'll draw a diagram for you, so that it's easier to understand.
First you have to understand that the perimeter is all the sides add up together.

Let's set up an equation, using l for the length, and w for the width.

5w + w = 48
Simplify
6w = 48
Divide by 6 on both sides
w = 8

Now the value we got is actually both widths (the green sides), so the width is actually 4. Which means that the length is 20.

The answer is 4ft by 20 ft.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)
