The graph shows the exponential regression model for data representing a rabbit population after x years. Which is true of the r
egression model?
The graph of the regression model is limited to whole-number values for x.
The graph of the regression model is limited to whole-number values for y.
The graph of the regression model cannot be used to approximate the population size for year 1.
The graph of the regression model can be used to predict the population size for any number of years in the future.

Answer:
C) 405.3 ft
Step-by-step explanation:
A triangle is a polygon with three angles and three sides. Types of triangle are scalene, isosceles, equilateral, right angled triangle.
Given a triangle with angles A, B, C and the corresponding sides directly opposite to the angles as a, b, c. The sine rule states that:
In the triangle formed by point C, ship B and ship A, we have ∠A = 82°, ∠B = 78°, c = AB = 140 ft. Hence:
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
82 + 78 + ∠C = 180
∠C + 160 = 180
∠C = 20°
Using sine rule:
a = distance from Ship B to the signal fire at point C
