Suppose f(x)=x^2. what is the graph of g(x)=f(3x)?

1 answer:

3 0

F(x)=x2,g(x)=f(3x)=(3x)2=9x2Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric aroung y axis. When x=1/3 or -1/3, then y=1.

A 180 foot length of fence is placed around a three-sided animal pen. Two of the sides of the pen are 72 feet and 78 feet. Does

zepelin [54]

Answer:

Yes

Step-by-step explanation:

Length of the third side

$180-(72+78)=30\ \text{ft}$

The hypotenuse is always the longest side of a right triangle.

So, the hypotenuse here is $c=78\ \text{ft}$

$a=72\ \text{ft},b=30\ \text{ft}$

$c=\sqrt{a^2+b^2}\\\Rightarrow c=\sqrt{72^2+30^2}\\\Rightarrow c=\sqrt{6084}\\\Rightarrow c=78\ \text{ft}$

The Pythagoras theorem applies so the fence does form a right triangle.
