Find the mean value of f(x) = x2 + 5 on [0, 5] |
|
Answer» Answer: The average value is = 1
Explanation: The average value of a function f ( x ) over an interval [ a , ] is ¯ x = 1 b − a ∫ b a f ( x ) d x
Here, f ( x ) = ( x − 3 ) 2 = x 2 − 6 x + 9
and [ a , b ] = [ 2 , 5 ]
Therefore, ¯ x = 1 5 − 2 ∫ 5 2 ( x − 3 ) 2 d x
= 1 3 ∫ 5 2 ( x 2 − 6 x + 9 ) d x
= 1 3 [ x 3 3 − 6 x 2 2 + 9 x ] 5 2
= 1 3 ( ( 125 3 − 75 + 45 ) − ( 8 3 − 12 + 18 ) ) = 1 3 ( 117 3 − 36 )
= 1 3 ⋅ 3

If two zeros of the polynomial p(x) = 2x4 - 3x? - 3x + 6x - 2 are √2 and√-2, find its other two zeros. |
|
Answer» Step-by-step explanation: Answer Since, it is given that 2
and − 2
are the zeroes of the polynomial p(X)=2x −3x 3 −3x 2 +6x−2, THEREFORE, (x− 2
) and (x+ 2
) are also the zeroes of the given polynomial. Now, consider the PRODUCT of zeroes as follows: (x− 2
)(x+ 2
) =(x) 2 −( 2
) 2 (∵a 2 −b 2 =(a+b)(a−b)) =x 2 −2 We now divide 2x 4 −3x 3 −3x 2 +6x−2 by (x 2 −2) as shown in the above image: From the division, we observe that the quotient is 2x 2 −3x+1 and the remainder is 0. Now, we FACTORIZE the quotient 2x 2 −3x+1 by equating it to 0 to find the other zeroes of the given polynomial: 2x 2 −3x+1=0 ⇒2x 2 −2x−x+1=0 ⇒2x(x−1)−1(x−1)=0 ⇒(2x−1)(x−1)=0 ⇒(2x−1)=0,(x−1)=0 ⇒x= 2 1
,x=1 Hence, the other two zeroes of p(x)=2x 4 −3x 3 −3x 2 +6x−2 are 2 1

Solve 2 upon x-1+3 upon y+1=2;3 upon x-1+2 upon y-1=13 upon 6 |
|
Answer» Answer: Step-by-step explanation: \begin{gathered}\FRAC{2}{x}+\frac{2}{3y}=\frac{1}{6}---(i)\\\\\frac{3}{x}+\frac{2}{y}=0\\\\\Rightarrow \frac{3y+2x}{xy}=0\\\\ \Rightarrow 3y+2x=0\\\\\Rightarrow 3y=-2x\\\\\Rightarrow y=\frac{-2x}{3}\end{gathered} x 2
+ 3y 2
= 6 1
−−−(i) x 3
+ y 2
=0 ⇒ xy 3y+2x
=0 ⇒3y+2x=0 ⇒3y=−2x ⇒y= 3 −2x
Substituting the value of y in equation (i) \begin{gathered}\frac{2}{x}+\frac{2}{3\times(-\frac{2x}{3}) } =\frac{1}{6} \\\\\Rightarrow\frac{2}{x}+\frac{2}{-2x}=\frac{1}{6} \\\\\Rightarrow\frac{2}{x}-\frac{1}{x} =\frac{1}{6} \\\\\Rightarrow \frac{1}{x} =\frac{1}{6}\end{gathered} x 2
+ 3×(− 3 2x
) 2
= 6 1
⇒ x 2
+ −2x 2
= 6 1
⇒ x 2
− x 1
= 6 1
⇒ x 1
= 6 1
CROSS Multiply \Rightarrow x=6⇒x=6 Now substitute the value of x=6 in y=-\frac{2x}{3}y=− 3 2x
\begin{gathered}y=-\frac{2\times 6}{3}\\ \\\Rightarrow y=-4\end{gathered} y=− 3 2×6
⇒y=−4

Answer» Step-by-step explanation: (i) In quadrilateral PQRS, AREA = ar(PQS) + ar(QRS) => Area of PQS = 1/2 × 4× 7 = 14 cm² => Area of PRS = 1/2 × 3 × 7 = 10.5 cm² Area = 14 + 10.5 = 24.5 cm² (ii) In quadrilateral ABCD, AREA = ar(ABC) + ar(ACD) => Area of ABC = 1/2 × 6 × 3.5 = 10.5 cm² => Area of ACD = 1/2 × 6 × 2 = 6 cm² Area = 10.5 + 6 = 16.5 cm² (iii) In polygon ABCDE, AREA = ar(ABC) + ar(ACDE) => Area of ABC = 1/2 × 4 × 12 = 24 cm² => Area of ACDE = 1/2 × 2 × (8+12) = 20 cm² Area = 24 + 20 = 44 cm² |

|
Answer» The GIVEN vertices of triangle are ( - 3, 5 ), ( 5, 4 ) and ( 5, - 2 ). Now, we know that to find the area of triangle having vertices, the formula is given by Here, Coordinates are ( - 3, 5 ), ( 5, 4 ) and ( 5, - 2 ). So,
So, on substituting the values, we get Additional Information :-Distance Formula :- • Distance formula is used to find the distance between two given Points. Section Formula:- • Section Formula is used to find the co ordinates of the POINT(Q) which divides the line segment joining the points A and B internally in the ratio m : n Midpoint Formula :- • Mid Point formula is used to find the Mid point on any line segment. |
