The Diameter is 60. The 60 represents the diameter as you may know the formula is C=d*Pi

Answer: 60 cm

Step-by-step explanation:

We know that the circumference of a circle is given by :-

$\text{Circumference}=\pi d$ , where d is the diameter of the circle.

Given: The circumference of a circle is $60\pi$ cm

$\Rightarrow\ 60\pi=\pi d$ , where d is the diameter of the circle.

Dividing $\pi$ both sides of the equation, we get

$d=60\text{ cm}$

Hence, diameter of of the circle = 60 cm.

Find f(x) and g(x) so that the function can be described as y = f(g(x)).<br><br> y = 4/x^2+9

dlinn [17]

I'm assuming all of (x^2+9) is in the denominator. If that assumption is correct, then,

One possible answer is $f(x) = \frac{4}{x}, \ \ g(x) = x^2+9$

Another possible answer is $f(x) = \frac{4}{x+9}, \ \ g(x) = x^2$

There are many ways to do this. The idea is that when we have f( g(x) ), we basically replace every x in f(x) with g(x)

So in the first example above, we would have

$f(x) = \frac{4}{x}\\\\f( g(x) ) = \frac{4}{g(x)}\\\\f( g(x) ) = \frac{4}{x^2+9}$

In that third step, g(x) was replaced with x^2+9 since g(x) = x^2+9.

Similar steps will happen with the second example as well (when g(x) = x^2)

Consider the graph f(x)=3 to the power of x. describe how to graph the transformation f(x-3)+2

Assoli18 [71]

Answer:

shift the graph horizontally to the right for 3 units and then shift vertically up 2 units

Step-by-step explanation:

f(x) = x³ vs f(x-3)+2

f(x-3) will shift the graph horizontally to the right for 3 units

+2: will shift vertically up 2 units
