Answer:
(x -6)^2 +(y -3)^2 = 2
Step-by-step explanation:
The midpoint (C) is the center of the circle:
C = ((5, 4) +(7, 2))/2 = ((5+7)/2, (4+2)/2) = (6, 3)
A circle with center (h, k) that goes through point (a, b) can be written as ...
(x -h)^2 +(y -k) ^2 = (a -h)^2 +(b -k)^2
Using the values for this problem, we get ...
(x -6)^2 +(y -3)^2 = (5 -6)^2 +(4 -3)^2
(x -6)^2 +(y -3)^2 = 2
Answer:
Step-by-step explanation:
Give the rate of change of sales revenue of a store modeled by the equation
. The Total sales revenue function S(t) can be gotten by integrating the function given as shown;

a) The total sales for the first week after the campaign ends (t = 0 to t = 7) is expressed as shown;


Total sales = S(7) - S(0)
= 6,860 - 0
Total sales for the first week = $6,860
b) The total sales for the secondweek after the campaign ends (t = 7 to t = 14) is expressed as shown;
Total sales for the second week = S(14)-S(7)
Given S(7) = 6,860
To get S(14);

The total sales for the second week after campaign ends = 13,720 - 6,860
= $6,860
Answer: Mode = 12
Explanation: The mode is the most frequent value, so it is the value that shows up the most. In this case, that would be the value "12" since it shows up three times (while the other values only show up once).
Perimeter = 2L + 2W
Let x = width and let 2x = length
Perimeter = 66
2x + 2(2x) = 66
2x + 4x = 66 --> 6x = 66 --> x = 66/6 --> x = 11
The width of the rectangle is 11 cm.
