Answer:

178.7 ft.

Step-by-step explanation:

The kite is (x + 5) ft above the ground. So we need to find x first.

Use the trigonometric identity Sine.

$Sin\ \theta=\frac{perpendicular}{hypotenuse}\\\\sin44=\frac{x}{250} \\\\x=250*sin44\\x=250*0.69\\x=173.66\ ft\\$

Rounding your answer to the nearest tenth would be 173.7 ft.

Now the kite is above the ground x + 5 which means

173.7 + 5 = 178.7 ft.

Answer:

$\large\boxed{x\in[-5,\ \infty)}$

Step-by-step explanation:

$f(x)=\dfrac{1}{2}x^2+5x+6\\\\\text{The coeficient of}\ x^2\ \text{is the positive number. Therefore the parabola is op}\text{en up}.\\\\\text{If a parabola op}\text{en up, then the graph increasing in interval}\ (h,\ \infty),\\\text{and decreasing in interval}\ (-\infty,\ h).\ \text{Where}\ h\ \text{is a first coordinate of a vertex.}\\\\\text{For}\ y=ax^2+bx+c,\ h=\dfrac{-b}{2a}.\\\\\text{We have}\ a=\dfrac{1}{2}\ \text{and}\ b=5.\ \text{Substitute:}\\\\h=\dfrac{-5}{2\left(\frac{1}{2}\right)}=-\cdot\dfrac{5}{1}=-5.$
