Graph f (x)=tan 3x. Identify period, x-intercepts and asymptotes

Marrrta [24]

Well the period of the tan(x) function is π. It means that when you add π on X axis you will get the same y axis value.

There is a little trick to find the period of functions like yours.
You just divide period of basic tan(x) function with, in your case 3.
So this mean you have
To = π/3

Function intercepts x axis when function is equal to 0.

tan(3x) = 0
3x = k * π
x = k * (π / 3)

There are only vertical asymptotes in tangent function.
You can easily see it if you look at the graph

tan(x) = ∞ , (π/2 + kπ)
tan(x) = -∞ (-π/2 + kπ).
x = π/2 + kπ
x = - π/2 + kπ

tan(3x) = ∞

3x = π/2 + kπ
x = π/6 + kπ/3

tan(3x) = -∞

3x = -π/2 + kπ
x = -π/6 + kπ/3

A tree of unknown height casts a shadow that is 18 feet long. If a person that is 5 ft 7 in casts a shadow that is 4 ft long, th

brilliants [131]

Answer:

25.

Step-by-step explanation:

5 ft 7 in = 5.583 ft.

We have 2 similar triangles here.

If h is the height of the tree, then:

h / 5.583 = 18/4

h = 18*5.583/4

h = 25.12 ft

Write a linear function that passes through (1,5) and (2,15)

Leokris [45]

Simple,

using $\frac{y1-y2}{x1-x2} =m (slope)$

find your slope...

$\frac{5-15}{1-2} = \frac{-10}{-1}=10$

thus, 10=m (slope)

Now, using y=mx+b to find your equation, plug in what you know...

Use any of the 2 coordinates.. (1,5)

5= 10(1)+b

5=10+b
-10 -10

-5=b

Thus, the equation to your line is...

y=10x-5.
