Answer:
Step-by-step explanation:
we know that
Applying the Intersecting Secant Theorem
substitute the values
Solve for ED
Answer:
y = x - 7
Step-by-step explanation:
Slope - intercept form: y = mx + b
2x - 2y = 14
-2y = -2x + 14
Divide the equation by (-2)
y = x - 7
Answer:
y+6 = -5/4(x-8)
Step-by-step explanation:
The point slope form of the equation of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y --6 = -5/4 ( x - 8)
y+6 = -5/4(x-8)

PART A:
The data is plotted in the graph below. The line best fit is drawn to show the trend of the data. Since the plots form a cluster that follows the line best fit and there are no outliers, the most likely coefficient is 0.94 which is a strong positive correlation.
PART B:
The value of slope between x = 5 and x = 10 is
Slope = (3-1) ÷ (10-5) = 2/5
The slope represents the rate of change of the radius, which is 2/5 for every 5 days
PART C:
The data in the table represents correlation, that the algae grow longer as the days increase. It might not be necessary a causation because the growth of algae doesn't necessarily depend on the number of days.
