. The height of an arrow shot on Neptune can be modelled by the quadratic function h(t) = 2.3 + 50t - 5.57t^2 , where time, t, is in
seconds and height, h(t), is in metres. Use the quadratic formula to
determine when the arrow will hit the surface.

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

The value √10 and √15 are plotted on the number line

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
