Ex 11 3 4 X2 25 Y2 100 1 Find Foci Latus Rectum Ex 11 3 As someone else stated, x 2 y 2 = 25 is a relationship describing a circle this link shows the generic equation and the meanings as such In this case, the center of the circle is at the point (0,0) and the radius is 25 units 1 Share Report Save level 1 6ySOLUTION 1 Begin with x 3 y 3 = 4 Differentiate both sides of the equation, getting D ( x 3 y 3) = D ( 4 ) , D ( x 3) D ( y 3) = D ( 4 ) , (Remember to use the chain rule on D ( y 3) ) 3x 2 3y 2 y' = 0 , so that (Now solve for y' ) 3y 2 y' = 3x 2, and Click HERE to return to the list of problems SOLUTION 2 Begin with (xy) 2 = x y 1 Differentiate both sides X 2 y 2 25 x 2y 10

And b = 4 The corresponding linear transformation rule is (p, q) → (r, s) = (05p 0866q 3464, 0866p 05q – 2) Line y = 4/5x 4 θ = Tan1 (4/5) = 3866°A reflection (or flip) is one kind of transformation The reflection of a point is another point on the other side of a line of symmetry Both the point and its reflection are the same distance from the line The following diagram show the coordinate rules for reflection over the xaxis, yaxis, the line y = x and the line y = x Scroll downReflect over the y = x When you reflect a point across the line y = x, the xcoordinate and ycoordinate change places If you reflect over the line y = x, the xcoordinate and ycoordinate change places and are negated (the signs are changed) Illustrative Mathematics Reflection over the line y x calculator

The clustered column chart is one of the most commonly used chart types in Excel In the next dialogue window, let's set cell F4 as a name for the Series, and cell F5 as a data range for the new Series Click OK Adding a new Series with one data point to the combined chart The color in that cell range matches the color in the stacked bar chart VBA 'Name macro Sub ColorChartBarsbyCellColor() 'Dimension variables and declare data types Dim txt As String, i As Integer 'Save the number of chart series to variable c c = ActiveChartSeriesCollectionCount 'Iterate through chart series For i = 1 To c 'Save Excel 13 Chart series formatting changes when different series data is selected In a workbook i need to create multiple identically formatted bar and line charts using different sets of data In Excel 10 I created the chart as i wanted it, duplicated it, then edited the data series in either the formula bar or the 'select data' window to Excel Charts Dynamic Labe
