Quiz: LogicExplain that, three colinear points cannot be on a circle. |
Answer» Answer Keys.Colinear PointsTHREE points are colinear, so all of them are on a line. If three are colinear, there are three cases.
Number of IntersectionsWe know that the maximum number of intersections, that a circle and a line can have is two. Definition of CircleA circle is a FIGURE that the radius is equal. Solution.For cases 2 and 3, let's EXCLUDE them. We know the maximum number of intersections is 2. Based on that, let's find the total number of ways.
There are three ways to choose the pair of points and two ways to choose a center. Total of 6 different circles. Now there are two general cases.
In either WAY, the circles cannot go through one point because the distance is different from the two points. More information.If one point is outside the circle, the distance from the circle is greater than the radius. If one point is inside the circle, the distance from the circle is less than the radius. |

Answer» Answer: In the graph, we find that the years are presented on the x-axis and the sales (in RS. crores) on the y-axis. The sales at any time (year) can be read from the graph exactly in the same WAY as we read the coordinates of a point. From the graph, we OBSERVE that: (i) (a) The sales in the year 2002 is Rs. 4 crore. (b) The sales in the year 2006 is Rs. 8 crore. (ii) (a) The sales in the year 2003 is Rs. 7 crore. (b) The sales in the year 2005 is Rs. 10 crore. (iii) The difference between the sales in 2002 and 2006 = Rs. 8 crore - Rs. 4 crore = Rs. 4 crore. (iv) The year in which there was the greatest difference between the sales compared to its previous year is the year 2005. |

Answer» Option b Step-by-step explanation: GIVEN:-In a rhombus, the length of the two diagonals are 3 meters and 4 meters respectively. To find:-Find its PERIMETER? Solution:-The lengths of the two diagonals are 3 m and 4 m Consider a ABCD rhombus AC = 3m and BD = 4 m We know that The diagonals bisect to each other at 90° AO = OC AO = AC/2 = 3/2 CM = 1.5 m BO=OD BD = BO/2 = 4/2 = 2 m ∆AOB is a right angled triangle By Pythagoras THEOREM: The square of the hypotenuse is equal to the sum of the squares of the other two sides =>AB^2 = AO^2+OB^2 =>AB^2 = (1.5)^2+2^2 =>AB^2 = 2.25 +4 =>AB^2 = 6.25 =>AB=√6.25 =>AB=2.5 m The length of the side=2.5 m We know that All sides are equal in a rhombus =>AB=BC=CD=DA=2.5m Perimeter of a rhombus = Sum of all sides =>Perimeter=4×length of its side =>P=4×2.5m =>P=10 m Answer:-Perimeter of the given rhombus is 10 m Used formulae:-
The square of the hypotenuse is equal to the sum of the squares of the other two sides

224) The total surface area of a closed cylinder is 3872 cm If its radiusis 14cm, then find the height of the cylinder and the volume of thecylinder. |
|
Answer» To find:
Solution: • Let's consider ABCD is a cylinder. Where,
• Let Height of cylinder be h m. ⠀⠀━━━━━━━━━━━━━━━━━━━⠀ « Now, By using the formula, → 2πr (r + h) = 3872 → 2 × 22/7 × 14(14 + h) = 3872 → 2 × 22 × 2(14 + h) = 3872 → 14 + h = 3872/88 → 14 + h = 44 → h = 44 - 14 → h = 30cm ⠀⠀━━━━━━━━━━━━━━━━━━━⠀ « Now, Let's find volume, As we know that, → Volume = πr²h → 22/7 × 14² × 30 → 22/7 × 196 × 30 → 22 × 28 × 30 → 18480cm³ ∴ Hence, Volume of the cylinder is 18480cm³. |

Lea, Paul, Tynos invests in a business in the ratio 1:3:5. If the profit from the business isR450 000, how much will each get? |
|
Answer» Answer: Chapter 3 A Factor Approach 3-1 If you had $1,000 now and invested it at 6%, how much would it be worth 12 years from now? Solution F = 1,000(F/P, 6%, 12) = $2,012.00 3-2 Mr. Ray deposited $200,000 in the Old and Third National Bank. If the bank pays 8% interest, how much will he have in the account at the end of 10 years? Solution F = 200,000(F/P, 8%, 10) = $431,800 3-3 If you can earn 6% interest on your money, how much is $1,000 paid to you 12 years in the FUTURE worth to you now? Solution P = 1,000(P/F, 6%, 12) = $497.00 3-4 Determine the value of P USING the appropriate factor. Solution P = F(P/F, 6%, 5) = $500(0.7473) = $373.65 3-5 Downtown is experiencing an explosive population growth of 10% per year. At the end of 2005 F = $500 i = 6% P 0 1 2 3 4 550 Chapter 3 Equivalence – A Factor Approach the population was 16,000. If the growth rate continues unabated, at the end of how many years will it take for the population to triple? Solution Use i = 10% to represent the growth rate. 48,000 = 16,000(F/P, 10%, N) (F/P, 10%, n) = 48,000/16,000 = 3.000 |
