If you plug in 5 for x, the radical ends up being (5-1) which is 4. The square root of 4 is 2, and the plus/minus symbol means the possible answers are 2 OR -2. When you plug in 1 for x the radical becomes (1-1) or zero. The square root of 0 is zero, and plus/minus zero are the same. This IS NOT a function because for x=10 and x=5, there are TWO DIFFERENT y values (each “x” can only have one y in a function)

Vinil7 [7]

Answer:

$270.3\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ADE

Find the value of h1

See the attached figure

h1=AD

$tan(25\°)=\frac{h_1}{180}$

Solve for h1

$h_1=(180)tan(25\°)\\h_1=83.94\ ft$

step 2

In the right triangle ABC

Find the value of h2

See the attached figure

h2=BC

$tan(46\°)=\frac{h_2}{180}$

Solve for h2

$h_2=(180)tan(46\°)\\h_2=186.40\ ft$

step 3

Find the height of the neighboring building

we know that

The height of the neighboring building is equal to

$h=h_1+h_2$

substitute the values

$h=83.94+186.40=270.34\ ft$

Round to the nearest tenth of a foot

$h=270.3\ ft$
