That's the distance formula, which is the Pythagorean Theorem applied to the points.
The distance between (a,b) and (c,d) is
a-c is the signed distance in the x direction between the points. b-d is the signed distance in the y direction between the points. Since the axes are perpendicular, these make a right triangle whose hypotenuse is the distance between the points.
Here that just means our distance is
Answer: B 4.1 units
Answer:
The function best models the situation.
Step-by-step explanation:
The values in the table do not lie over a straight line because their slope is not a constant; for example
we see here that therefore a linear equation cannot represent this situation.
The values in the table are increasing exponentially , therefore the equation modeling the situation will be of the form:
we take two points from the table for evaluating and
namely points
and
thus we have
(1).
(2).
From equation (1) we solve for
and put this value into equation (2)
with this value , we solve for
in equation (1):
Thus we have the equation
