5. Prove that the perpendicular at the point of contact to the tangent to a circle passesthrough the centre |
|
Answer» Step-by-step EXPLANATION: Let O be the centre of the given circle. AB is the tangent drawn TOUCHING the circle at A. DRAW AC ⊥ AB at point A, such that point C lies on the given circle. ∠OAB = 90° (Radius of the circle is perpendicular to the tangent) Given ∠CAB = 90° ∴ ∠OAB = ∠CAB This is POSSIBLE only when centre O lies on the line AC. Hence, perpendicular at the point of CONTACT to the tangent to a circle passes through the centre of the circle. |

Answer» Step-by-step explanation: A=40,000 Let part invested in 4 % be x so principal = x I(4) = x * 4 * 1/100 = 4x/100 let part invested at 6 % be y so principal in this case = y so I(6) = y * 6 * 1/100 = 6y/100 now total I = 2130 which implies (4x + 6y)= 213000 and also A= 40000 = x +y +2130 so x + y = 37870 SOLVING both EQS we GET y = 30760 and x= 7110 hence first amount is 7110 and second is 30760 hope this helps you!! |

Write t the coordinates of the point which |
|
Answer» Answer: Step-by-step explanation: The COORDINATES of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located. Ordered Pair The coordinates are WRITTEN as an "ordered pair" as shown below. The letter P is simply the name of the point and is used to distinguish it from others. Ordered pair SHOWING coordinates of a point The two numbers in parentheses are the x and y coordinate of the point. The first number (x) specifies how far along the x (horizontal) axis the point is. The second is the y coordinate and specifies how far up or down the y axis to go. It is called an ordered pair because the order of the two numbers matters - the first is ALWAYS the x (horizontal) coordinate. The sign of the coordinate is important. A positive number means to go to the right (x) or up(y). NEGATIVE numbers mean to go left (x) or down (y). (The figure at the top of the page has the values of the axes labelled with the appropriate sign). |
