Linda goes water-skiing one sunny afternoon. After skiing for 15 min, she signals to the driver of the boat to take her back to
trasher [3.6K]
60 = a * (-30)^2
a = 1/15
So y = (1/15)x^2


abc)
The derivative of this function is 2x/15. This is the slope of a tangent at that point.
If Linda lets go at some point along the parabola with coordinates (t, t^2 / 15), then she will travel along a line that was TANGENT to the parabola at that point.
Since that line has slope 2t/15, we can determine equation of line using point-slope formula:
y = m(x-x0) + y0
y = 2t/15 * (x - t) + (1/15)t^2
Plug in the x-coordinate "t" that was given for any point.


d)
We are looking for some x-coordinate "t" of a point on the parabola that holds the tangent line that passes through the dock at point (30, 30).
So, use our equation for a general tangent picked at point (t, t^2 / 15):
y = 2t/15 * (x - t) + (1/15)t^2
And plug in the condition that it must satisfy x=30, y=30.
30 = 2t/15 * (30 - t) + (1/15)t^2
t = 30 ± 2√15 = 8.79 or 51.21
The larger solution does in fact work for a tangent that passes through the dock, but it's not important for us because she would have to travel in reverse to get to the dock from that point.
So the only solution is she needs to let go x = 8.79 m east and y = 5.15 m north of the vertex.

After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6,3), B'(-2, 1)
Fed [463]

Answer:

  • A(3, -6)
  • B(1, 2)
  • C(7, -1)

Step-by-step explanation:

Rotation by -90° about the origin is the transformation ...

  (x, y) ⇒ (y, -x)

So, your pre-image points are ...

  A'(6, 3) ⇒ A(3, -6)

  B'(-2, 1) ⇒ B(1, 2)

  C'(1, 7) ⇒ C(7, -1)

ahrayia [7]

Answer:

108 children were drinking apple juice. $432 were spent on pizza.

Step-by-step explanation:

How many children were drinking apple juice:

567 - 323 - 136 = 108

How many children were eating pizza:

108 * 2 = 216

How much was spent on pizza:

216 * $2 = $432
