Answer:
(-1,5) and
are points on the graph
Step-by-step explanation:
Given

Required
Determine which point in on the graph
To get which of point A to D is on the graph, we have to plug in their values in the given expression using the format; (x,g(x))
A. (-1,5)
x = -1
Substitute -1 for x in 

Convert to index form

Change / to *


This satisfies (-1,5)
<em>Hence, (-1,5) is on the graph</em>
<em></em>
B. (1,0)
x = 1
Substitute 1 for x



<em>(1,0) is not on the graph because g(x) is not equal to 0</em>
C. 
x = 3
Substitute 3 for x


Apply law of indices


This satisfies 
<em>Hence, </em>
<em> is on the graph</em>
<em></em>
D. 
x = -2
Substitute -2 for x


Convert to index form



Change / to *


This does not satisfy 
<em>Hence, </em>
<em> is not on the graph</em>

Answer:
The length of the tunnel is 7.66667 inch
Step-by-step explanation:
We are given
1 inch =60 miles
now, we can find for 1 mile
so,
60 miles = 1 inch
we get

we are given
total length is 460 miles
so, we can multiply both sides by 460

now, we can simplify it

So,
The length of the tunnel is 7.66667 inch
