520 pages. 390 divided by 3 is 130. Take that times 4 and you get 520. To check it, I took 520 divided by four (or you can multiply by 1/4) and got 130. Hope it helps!

Given f(x)=cos c and g(x)=cot x, what are the domain and range of f(g(x))?
ololo11 [35]

Answer:

Alternative C is the correct answer

Step-by-step explanation:

The first step is to determine the composite function;

f[g(x)]

f[g(x)]=cos[cot(x)]

We then employ a graphing utility to determine the range and the domain of the new function.

The range is the set of y-values for which the function is defined. In this case it is;

[-1,1]

On the other hand, the domain refers to the set of the x-values for which the function is real and defined. In this case; it is the set of real numbers x except x does not equal npi for all integers n.

If g(x)=x+1/x-2 and h(x)=4-x what is the value of (g•h)(-3)
djyliett [7]

The Answers is


g(x) = (x + 1)/(x - 2)

h(x) = 4 - x


g(h(x)) = (4 - x + 1)/(4 - x - 2) = (5 - x)/(2 - x)


g(h(-3)) = (5 - (-3))/(2 - (-3)) = (5 + 3)/(2 + 3) = 8/5


g(h(-3)) = 8/5.

The length of a rectangle is 24 more than its width. Find the area of the rectangle if its perimeter is 100 cm.
Serggg [28]

Answer:

481

Step-by-step explanation:

Lets say width = x

Length = x+24

Perimeter is 100 so

100=x+24+x+24+x+x

100=4x+48

100-48=4x

52=4x

x=13

So width = 13

Length = 37

37x13=481
