Answer:

$x = 375.3$

Step-by-step explanation:

Given

See attachment for illustration

Required

Determine the horizontal distance

The horizontal distance is the distance between the technician and the base of the pole.

Represent this with x.

The relationship between x, 175ft and 25 degrees is represented as:

$tan(25^{\circ}) = \frac{175}{x}$ --- i.e. tan formula

Multiply both sides by x

$x * tan(25^{\circ}) = \frac{175}{x} * x$

$x * tan(25^{\circ}) = 175$

Make x the subject

$x = \frac{175}{tan(25^{\circ})}$

$x = \frac{175}{0.4663}$

$x = 375.294874544$

$x = 375.3$ --- approximated

<em>The distance is approximately 375.3ft</em>

Which equation represents the line that passes through (-8.11) and<br>(4,7/2)?

Len [333]

Answer:

$y=-5/8x+6$

Step-by-step explanation:

$m=\frac{7/2 - 11}{4--8}$

$m=\frac{-15/2}{12}$

$m=-5/8$

$y=-5/8x+b$

$(-8,11)$

$11=-5/8 \times -8+b$

$b=11-(-5/8)(-8)$

$b=6$
