Find the ratio in which y axis divides the loline segment joining the point A (5,-6),B (1,-4) |
|
Answer» Given Line segment joining two points (5,-6) and (1,-4) is DIVIDED by y-axis. To Find:
Sectional Formula Let P(x₁,y₁) and Q(x₂,y₂) be two points. Let the point R(x,y) divide the line segment joining the points P and Q internally in the ratio m:n, then Solution: Let the y-axis divides the given line segment in λ:1 and point of intersection of y-axis and given line segment be (0,b)
Diagram: Now, by using sectional formula, we GET On comparing x-coordinate of both the SIDES we get,
From (1), we get ✏ λ=-5 So, y-axis divides the given line segment in 5:1 externally Hence, the required ratio is 5:1 |

If secQ=5/4, Find the value of SinQ-2CosQ/TanQ-CotQ |
Answer» Given :-
To Find :-
Formula used :-
Solution :-→ secQ = (5/4) = Hypotenuse/Base So, → Hypotenuse = 5 → Base = 4 So, By PYTHAGORAS Theoram , → Perpendicular = √(5)² - (4)² → Perpendicular = √(25 - 16) → Perpendicular = √9 → Perpendicular = 3 . _______________So,→ SinQ = Perpendicular/Hypotenuse = 3/5 → cosQ = Base/Hypotenuse = 4/5 → TanQ = Perpendicular/Base = 3/4 → CotQ = Base/Perpendicular = 4/3 ________________Putting All Values now, we get :- → (SinQ - 2CosQ) /(TanQ - CotQ) → [ (3/5) - 2*(4/5) ] / [ (3/4) - (4/3) ] → [ (3- 8)/(5) ] [ ( 9 - 16) / (12) ] → (-5/5) / (-7/12) → (-1) * (-12/7) → (12/7) (ANS). |

Answer» Question :Peter invested a certain sum of money in a simple interest bond WHOSE value grew to Rs. 300 at the end of 3 years, and to Rs. 400 st the end of another 5 years. What was the RATE of interest? ANSWER :Let the sum of money invested i.e Principal be Rs. P an Rate of interest be R % . At the end of 3 years sum amounts to Rs. 300 Time ( T ) = 3 year Amount = Rs. 300 ⇒ P( 1 + TR / 100 ) = 300 ⇒ P( 1 + 3R / 100 ) = 300 ⇒ P{ ( 100 + 3R ) / 100 } = 300 -- ( EQUATION 1 ) At the end of another 5 years sum amounts to Rs. 400 Time ( T ) = 3 years + 5 years = 8 years Amount = Rs. 400 ⇒ P( 1 + TR / 100 ) = 400 ⇒ P( 1 + 8R / 100 ) = 400 ⇒ P{ ( 100 + 8R ) / 100 } = 400 -- ( Equation 2 ) Dividing Equation 1 by Equation 2 ⇒ P{ ( 100 + 8R ) / 100 } / P{ ( 100 + 3R ) / 100 } = 400 / 300 ⇒ ( 100 + 8R ) / ( 100 + 3R ) = 4 / 3 ⇒ 300 + 24R = 400 + 12R ⇒ 24R - 12R = 400 - 300 ⇒ 12R = 100 ⇒ 3R = 25 ⇒ R = 25/3 = 8.33 % Therefore the Rate of interest was 25/3 % or 8.33 %. |
