Answer:
1.8 miles
Step-by-step explanation:
For this case we can model the problem as a rectangle triangle.
We know:
Length of the sides of the triangle
We want to know:
Length of the hypotenuse
Using the Pythagorean theorem we have:

Then, the distance that he would have saved if he travels directly is:

Answer:
he would have saved:
1.8 miles
Scientific notation uses expression which gives easy access of order. The greatest number is
.It is greater by smallest number by 500 times.
<h3>How to convert a number to scientific notation?</h3>
It is usually of the form
exponent of 10 starts)
(we have 1 ≤ |a| < 10 ) (where |a| is magnitude of a without sign)
This notation is used to get some idea of how large or small a number is in terms of power of 10.
<h3>What are some basic properties of exponentiation?</h3>
If we have
base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:

The given numbers are:
- First number =

- Second number =

- Third number =

The smallest number is 1,100 and greatest is 550,000
Getting the division to get to know how many times the greatest number is larger than the smallest number, we get:

Thus, it is found that greatest number is
. It is greater by smallest number by 500 times.

Answer:
g(4) = 7 and f(g(4)) = 43
Step-by-step explanation:
First find g:
g(x) = 3x-5
g(x) = 3(4) - 5
g(x) = 12 - 5
g(x) = 7
Plug in:
f(g(4))
f(7)
Now, find f:
7^2 - 7 + 1
49 - 7 + 1
42 + 1
f(x) = 43
2 x (5-2)^3
2 x (3)^3
2 x 27
