$D:x-1\geq0\\
D:x\geq1\\\\$

$\hbox{ range of } \sqrt {x-1} \hbox{ is } \langle0,\infty)\\
\hbox{ range of } -\frac{3}{4}\sqrt {x-1} \hbox{ is } \langle-\frac{3}{4}\cdot0,-\frac{3}{4}\cdot\infty)=(-\infty,0\rangle\\
\hbox{ range of } -\frac{3}{4}\sqrt {x-1}+4 \hbox{ is } (-\infty+4,0+4\rangle=(-\infty,4\rangle\\

At a store, carpet is sold in units of 10 square yards.

We can generalise this by finding the equation of the line.
The gradient is: 15

We can take when x = 10, and y = 150 to find the equation of the line.
y - 150 = 15(x - 10)
y - 150 = 15x - 150
y = 15x

Thus, when x = 80, y = $1200 (ie B)

The height of the Eiffel Tower is 1050 feet. From the top, the angle of depression to a soccer ball on the ground is 20 degrees.

mihalych1998 [28]

Since the angle of depression from the Eiffel tower is congruent to the angle of elevation from the soccer ball, the angle of elevation from the soccer field is 20°

Now, we can use the trigonometric function tangent to find the distance from the soccer ball to the base of the Eiffel Tower:
 $tan( \alpha )= \frac{opposite.side}{adjacent.side}$
$tan(20)= \frac{1050}{a}$
$a= \frac{1050}{tan(20)}$
$a=2884.85$

We can conclude that the distance from the soccer ball to the base of the Eiffel Tower is 2884.85 feet.
