The amount of money left on a loan that Kira owes her grandmothers is represented by the function k(t)=280(.88)^t where k(t) represents the amount of money left on a the loan and t represents the time, in years. Find r, the percent change and explain what it represents.
Answers
k(t) = 280(0.88)^t
t = 1 ; t = 2 ; t = 3
k(1) = 280(0.88)¹ = 280(0.88) = 246.40
k(2) = 280(0.88)² = 280(0.7744) = 216.83
k(3) = 280(0.88)³ = 280(0.681472) = 190.81
280 - 246.40 = 33.60 ⇒ 33.60/280 = 0.12
246.40 - 216.83 = 29.57 ⇒ 29.57/246.40 = 0.12
216.83 - 190.81 = 26.20 ⇒ 26.20/216.83 = 0.12
The rate is 0.12 or 12%

Answer:
Distance = 7.8 units
Step-by-step explanation:
In coordinate geometry, the distance between the 2 points is given by
where (x1,y1) and (x2,y2) are coordinates of the 2 points.
Above the 2 points given are, (-2,-1) and (3,5).
x1 = -2 , y1 = -1 , x2 = 3, y2 = 5
Distance = 7.8102 units
To the nearest tenth, Distance = 7.8 units

Final answer:
To determine if the line of best fit is appropriate for the data, plot the residuals on a graph and examine the pattern. In this case, the residual plot does not show a linear or curved pattern, indicating that the line of best fit is not appropriate for the data.
Explanation:
The residual plot shows the difference between the observed Y-values and the predicted Y-values. To plot the residuals, subtract the predicted Y-values from the observed Y-values for each corresponding X-value. Then plot the resulting points on a graph. In this case, the points are:
(1, 0.86), (2, -0.25), (3, -1.66), (4, -2.34), (5,-4.1).
To determine if the line of best fit is appropriate for the data, we need to examine the pattern of the residual plot. If the points have no pattern or are evenly distributed about the x-axis, it indicates that the line of best fit is appropriate. In this case, the points do not exhibit a linear or curved pattern, and they are not evenly distributed about the x-axis. Therefore, the residual plot does not show that the line of best fit is appropriate for the data.
Hence, the correct answer is: C. No the points are in a linear pattern.
