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

Use the properties of real numbers to rewrite the expression. 2/5 * (-7) * 5/2

Mama L [17]

For this case we have the following expression:

$\frac{2}{5}*(- 7)*\frac{5}{2}$

Using the associative property we can rewrite the expression in the following way:

$(\frac{2}{5}*\frac{5}{2})*(-7)$

Finally, simplifying we have:

$(1) (- 7)$

$-7$

Answer:

Rewriting the expression we have that the result is:

d. -7
