HEEELP let f(x) =1/x-3 and g(x)=√x+5. What is the domain of (f o g)(x)

Options

a) [-5,-4)U(-4, inf)

b) [-5,-3)U(-3,inf)

c)[-f,4)U(4,inf)

d)[-5,3)U(3,inf)

(c)

Step-by-step explanation:

Given

Here,

To get , replace in by

Using and  it can be concluded that the domain of is all real numbers except 0.

Therefore, its domain is given by

Option (c) is correct.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
