ENGLISH DECLAMATION PIECES If you can keep your head when all about you Are losing theirs and blaming it on you, If you can trust yourself when all men doubt you, But make allowance for their doubting too; If you can wait and not be tired by waiting, Or being lied about, don't deal in lies, Or being hated, don't give way to hating, And yet don't look too good, nor talk too wise: If you can dream—and not make dreams your master; If you can think—and not make thoughts your aim; If you can meet with Triumph and Disaster And treat those two impostors just the same; If you can bear to hear the truth you've spoken Twisted by knaves to make a trap for fools, Or watch the things you gave your life to, broken, And stoop and build 'em up with worn-out tools: If you can make one heap of all your winnings And risk it on one turn of pitch-and-toss, And lose, and start again at your beginnings And never breathe a word about your loss; If you can force your heart ...
A circle having radius 5 units and passing through point (4,3) and its centre lies on line 2x+y-1=0.. Find the equation of circle Answer: (x - 1)² + (y + 1)² = 5² or (x + 1)² + (y - 3)² = 5² Step-by-step explanation: We know that the equation of a circle is expressed as (x - h)² + (y - k)² = r² Given: r = 5 Unknown: (h, k) To solve for the center, were given the following clues; (1) the circle is passing through point (4, 3) (2) the center lies on the line 2x + y - 1 = 0 Identify the two equations in which you can get the center of the circle; Equation 1 = 2x + y - 1 = 0 Equation 2 = *I used the distance formula in equation 2. This will help me identify the missing center of the circle. Solve for y in equation 1: 2x + y - 1 = 0 2x + y = 1 y = 1 - 2x Substitute the value of y in equation 2: Substitute the value of x in equation 1: When x = 1, y = -1 When x = -1, y = 3 Substitute the values of x and y to (h, k). Yoll then get: (x - 1)² + (y + 1)² = 5² or (x + 1)² + (y - 3)² = 5² ^...
x²+y²+4x-4y-28=0 to standard form then give the coordinates of the center and the radius ( i hope yall help me) Answer: The coordinates of the center of the circle is (-2,2) while its radius is 6. Step-by-step explanation: Step 1: Write the given The equation is an equation for circle since the coefficient and sign of and is equal. Step 2: Find the center-radius form of the given as well as the center coordinates and the radius of the circle. Center-radius form: Where (h,k) will be the coordinates of the center of the circle In order to transform the given equation into the center-radius form then we will use the technique "completing the square" Group the terms with the same variable and isolate the constant: In completing the square, we need to work both on x and y variable separately. Divide the coefficient of 4x by 2 and square the resulting answer: Divide teh coefficient of -4y by 2 and square the resulting answer: The equation will result to: 4+4 is also added ...
