Well according to the slope intercept equation.

Y = mx +/- b

The slope is the value m
The y intercept is b

To graph the function, one sure way to do it is simply make a table of values picking any x values that fall within the graph space, and finding out the resulting y values and using the points to graph.

For instance for the first graph, if x = 0, y = 5, that is one possible point. Keep on choosing x values to graph.

The angle of depression from the top of a flag pole to a point on the ground is 30°. If the point on the ground is 75 feet from

Cerrena [4.2K]

Answer:

Height of flag pole to the nearest foot is 43 feet

Step-by-step explanation:

In the diagram we have flag pole AB and C is the point on the ground.

It is given that angle of depression is 30°

and the distance of the point C from the base B is 75 feet

so we have

BC= 75 feet

∠C = 30°

AB= h feet

now in right ΔABC

$tan C = \frac{opposite \ side }{base} \\tan C=\frac{AB}{BC}$

now we plug AB= h , ∠C= 30° and BC =75

$tan 30= \frac{h}{75}$

$75 tan30 = h$ ( multiply both sides by 75)

$h= 75 tan 30 =75 (0.5773)\\ h= 43.3 feet\\$

Height of flag pole to the nearest foot is

h= 43 feet
