Equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
In this case:
<span>center (2,7) and radius 4 so h = 2, k = 7 and r = 4
</span>Equation:
(x - 2)^2 + (y - 7)^2 = 4^2
(x - 2)^2 + (y - 7)^2 = 16
Hope it helps.
Not sure about this but, is it a line?
Answer:
50
Step-by-step explanation:
Option C:
Solution:
Given expression: 2 ln 8 + 2 ln y
Applying log rule 
in the above expression.
⇒ 
Applying log rule 
in the above expression.
⇒ 
We know that 
⇒ 
Hence, the expression in single natural logarithm is .
Answer:
1) A. y = x + 2
Once a line of best fit has been placed upon a scatter graph it is straightforward to find the equation. The general equation of a straight line is: y = mx + c Where m is the slope (gradient) of the line and c is the y-intercept.
4) d. strong positive correlation.
The slope of the line is positive. Most points lie close to the line.
