To win a prize at a fair you must throw a coin into a space that is 7.0 cm long and 4.0 cm wide. what is the area of the space you are aiming for? express your answer to the correct number of significant figures.

Alright, lets get started.

space that is 7.0 cm long and 4.0 cm wide it means space is in rectangular shape.

The lenght of the space = 7 cm

The width of the shape = 4 cm

The formula of area of rectange = length * width

The area of rectange =

The area of rectange = 28 square cm  

So, the area of the space you are aiming for 28 square cm.    :   Answer

Hope it will help :)

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!

make sure you have version 2.50
