Numbers and expressions written in scientific notation are often used to represent measurement in a real-life situations. for each of the following numbers written in scientific notation, describe a real-life situation using the number and its corresponding unit as the context. here's an example:

the following situation is modeled by the expression 4.5368 ∙ 103 cubic kilometers:

the average volume of each of the five great lakes is approximately 4.5368 ∙ 103 cubic kilometers.
make sure to use complete sentences in your answers.
1.6094 ∙ 105 centimeters
2.94 ∙ 103 square feet
2.4 ∙ 104 milliliters
6.3781 ∙ 103 kilometers
3.2228 ∙ 108 cubic miles

i believe the answer is d.

hope it you! : d

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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!
