Answer:
(2.5, -7)
Step-by-step explanation:
Given:
Two end points of a line segment are given as:
(-8, -10) and (6, -6)
The ratio of partition is 3 : 1.
Let the line segment be AB with A(-8, -10) and B(6, -6). Let point P(x,y) divide the line segment AB in the ratio 3 : 1.
In order to find the point P, we use section formula which is given as:
Where, are end points of line segment AB divided in the ratio m : n by the point
.
Now, plug in the given values and solve for the coordinates of P. This gives,
Therefore, the coordinates of the point on the directed line segment from (-8, -10) to (6,−6) that partitions the segment into a ratio of 3 to 1 is (2.5, -7).
The percentage rate of increase is 36.2% and the exponential function represent the growth.
<h3>What is an exponential function?</h3>It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent
where 'a' is a constant and a>1
We have exponential function:
If we compare with
If 1+r > 1
1.362 > 1
So the growth rate r is
1 + r = 1.362
r = 0.362
r = 0.362×100
r = 36.2%
Thus, the percentage rate of increase is 36.2% and the exponential function represent the growth.
