the quadratic equation -10x^2+11x=-8 represents the track followed by a missile. calculate the two values of x when the missile is in the same horizontal plane.
+23246 Starting with -10x² + 11x = -8, we can get -10x² + 11x + 8 = 0 that can be represented by the function:
y = -10x² + 11x + 8. This give a graph of a parabola which has an infinite number of pairs of x-values that
have the same y-value (on the same horizontal line) from ground level to its maximum.
I'm not understanding what you mean by the "same horizontal plane".
+128407 The missile will be in the same horizontal plane at many pairs of x values.....however, if you mean at what x values will the height = 0 , look at the graph here......https://www.desmos.com/calculator/yywqknblth
And the ht. = 0 when x = -0.5 and when x = 1.6
