AndCos (A+B)=4/5 and Sin (A+B) = 24/25find the value of tan 2A |
|
Answer» Answer: The value of tan(2A) is \frac{3}{4}[/tex] Step-by-step explanation: Given sin(A+B)=\frac{24}{25}sin(A+B)= 25 24
cos(A-B)=\frac{4}{5}cos(A−B)= 5 4
we have to find tan2A If sin(A+B)=\frac{24}{25}sin(A+B)= 25 24
then PERPENDICULAR is 24 and HYPOTENUSE is 25 then By PYTHAGORAS Theorem third side can be calculated as 25^{2}=24^{2}+Base^225 2 =24 2 +Base 2
⇒ Base is 7 Hence, tan(A+B)=\frac{24}{7}tan(A+B)= 7 24
Similarly, if cos(A-B)=\frac{4}{5}cos(A−B)= 5 4
then base is 4 and hypotenuse is 5 then By Pythagoras Theorem third side can be calculated as 5^{2}=4^{2}+Perpendicular^25 2 =4 2 +Perpendicular 2
⇒ Perpendicular is 3 Hence, tan(A-B)=\frac{3}{4}tan(A−B)= 4 3
∵ B>A, then A-B is negative.hence, taken negative tan(A-B)=\frac{-3}{4}tan(A−B)= 4 −3
tan(2A)=tan((A+B)+(A-B))= \frac{tan(A+B)+tan(A-B)}{1-tan(A+B)\times tan(A-B)}tan(2A)=tan((A+B)+(A−B))= 1−tan(A+B)×tan(A−B) tan(A+B)+tan(A−B)
⇒ tan(2A)=\frac{\frac{24}{7}+(\frac{-3}{4})}{1-\frac{24}{7}\times (\frac{-3}{4})}tan(2A)= 1− 7 24
×( 4 −3
) 7 24
+( 4 −3
)
=\frac{\frac{75}{28}}{\frac{100}{28}}=\frac{3}{4} 28 100
28 75
= 4 3

A bag contains 5 red balls and some of blue balls. If the probability of a drawing a blue ball is doubled that of a ref ball . Find the number of blue balls in the bag. |
|
Answer» Given that, a BAG CONTAINS 5 red balls and some BLUE balls. Number of red balls = 5 Let us assume that the bag contains 'x' blue balls. Therefore, the total number of balls = x + 5 Now, Probability = (Number of favourable outcomes)/(Total number of outcomes) For Red balls: Number of favourable outcomes = 5 Total number of outcomes = x + 5 P(red balls) = 5/(x + 5) For blue balls: Number of favourable outcomes = x Total number of outcomes = x + 5 P(red balls) = x/(x + 5) Also given that, the probability of a drawing a blue BALL is doubled that of a ref ball. According to question, ⇒ x/(x + 5) = 2 × [5/(x + 5)] The denominator, throughout cancel. We left with ⇒ x = 2(5) ⇒ x = 10 Therefore, There are 10 blue balls in the bag. |
