Answer:
22.36 mile.
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, y is the distance between starting point and the end point.
Thus we can obtain the value of y by using the pythagoras theory as show below:
Note: y is the longest side other wise known as the Hypothenus.
y² = 10² + 20²
y² = 100 + 400
y² = 500
Take the square root of both side
y = √500
y = 22.36 mile
Therefore, the distance between the starting point and the end point is 22.36 mile
we know that
if the exponential function passes through the given point, then the point must satisfy the equation of the exponential function
we proceed to verify each case if the point satisfied the exponential function
<u>case A</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function not passes through the point
<u>case B</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function passes through the point
<u>case C</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function not passes through the point
<u>case D</u>
For calculate the value of y in the equation and then compare with the y-coordinate of the point
so
therefore
the exponential function passes through the point
therefore
<u>the answer is</u>
