Answer:

Percent error = 15.79%

Step-by-step explanation:

Given the following data;

Experimental value = 12cm

Actual value = 14.25cm

To find the percentage error;

Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

Percent \; error = \frac {experimental \;value - actual \; value}{ actual \;value} *100

Substituting into the equation, we have;

Percent \; error = \frac {12 - 14.25}{14.25} *100

Percent \; error = \frac {2.25}{14.25} *100

Percent \; error = 0.1579 *100

Percent error = 15.79%

A hovercraft takes off from a platform. Its height (in meters), xx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=?
tangare [24]

Answer: 5 seconds

<u>Step-by-step explanation:</u>

Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).

h(x) = -2x² + 20x + 48

      a=-2    b=20   c=48

Axis of symmetry: x = \frac{-b}{2a}

                                 = \frac{-20}{2(-2)}

                                 = \frac{-20}{-4}

                                 = 5
