If -2 and 3 are the zeroes of the quadratic polynomial x²+(p+1)x+q, then find the values of p and q

Answer»

$\large\underline{\sf{Given- }}$

-2 and 3 are the zeroes of the quadratic POLYNOMIAL x² + (p + 1) X + q

$\large\underline{\sf{To\:Find - }}$

$\: \: \: \: \: \: \: \: \bull \sf \: values \: of \: p \: and \: q$

$\large\underline{\sf{Solution-}}$

We know that

$\sf \: If \: \alpha \: and \: \beta \: are \: zeroes \: of \: f(x) = {ax}^{2} + bx + c \: \: then$

$\boxed{\red{\sf Sum\ of\ the\ zeroes \: = \alpha + \beta =\dfrac{-coefficient\ of\ x}{coefficient\ of\ x^{2}}}}$

OR

$\boxed{\purple{\tt Sum\ of\ the\ zeroes = \alpha + \beta =\dfrac{-b}{a}}}$

And

$\boxed{\red{\sf Product\ of\ the\ zeroes = \alpha \beta =\dfrac{Constant}{coefficient\ of\ x^{2}}}}$

OR

$\boxed{\purple{\tt Product\ of\ the\ zeroes = \alpha \beta =\dfrac{c}{a}}}$

Now,

Given quadratic polynomial is

$\: \: \: \: \: \: \: \: \bull \: \: \sf \: f(x) \: = \: {x}^{2} + (p + 1)x + q$

↝ On Comparing with ax² + bx + c, we get

$\: \: \: \: \: \: \: \: \bull \sf \: a \: = \: 1$

$\: \: \: \: \: \: \: \: \bull \sf \: b \: = \: p + 1$

$\: \: \: \: \: \: \: \: \bull \sf \: c \: = \: q$

↝ Aɢᴀɪɴ,

↝ -2 and 3 are the zeroes of the quadratic polynomial x² + (p + 1)x + q,

$\: \: \: \: \: \: \: \: \bull \sf \: \alpha = - \: 2$

$\: \: \: \: \: \: \: \: \bull \sf \: \beta \: = \: 3$

Now,

$\rm :\longmapsto\: \alpha + \beta = - \: \dfrac{b}{a}$

$\rm :\longmapsto\: - 2 + 3 = - \: \dfrac{(p + 1)}{1}$

$\rm :\longmapsto\:1 = - p - 1$

$\bf\implies \:p \: = \: - \: 2$

Also,

$\rm :\longmapsto\: \alpha \beta = \dfrac{c}{a}$

$\rm :\longmapsto\:( - 2) \times 3 = \dfrac{q}{1}$

$\bf\implies \:q = - \: 6$

$\overbrace{ \underline { \boxed { \bf \therefore \: The \: value \: of \:p = - 2 \: \: and \: \: q = - 6}}}$

Question / 11 point) The angles shown are supplementary. What is the value of x?(5x)95°1802795

Answer»

ong>Given : angles are supplementary

5x° and 95°

To FIND : Value of X

180

17

95

Solution:

Angles are supplementary if they adds upto 180°

5x° and 95° are supplementary

=> 5x° + 95° = 180°

=> x° + 19° =36°

=> x° = 17°

=> x = 17

49.	ABCD is a square of side 70cm. Four quarter circle are drawn with each vertex as centre as shown in the figure. Find the area of the shaded region.
Answer» ong>Answer: The area of the shaded REGION is 1051.55 sq cm Step-by-step explanation: As there are four quarter circles with each vertex as their centre , that means that the measurement between the vertex to the MID point of the line is the radius of the quarter circles. r = 35 cm. All the 4 QUARTERS circles has the same radius . Area of the shaded region = Area of square ABCD - Area of 4 quarter circles = ( Side^2) - ( 4 × Area of a quarter circle) All quarter circles have same RADII . = (70^2) - ( 4 × (πr^2/4) ) = 4900 - ( π × (35^2) ) = 4900 - 3848.45 = 1051.55

ABCD is a square of side 70cm. Four quarter circle are drawn with each vertex as centre as shown in the figure. Find the area of the shaded region.

Answer»

ong>Answer:

The area of the shaded REGION is 1051.55 sq cm

Step-by-step explanation:

As there are four quarter circles with each vertex as their centre , that means that the measurement between the vertex to the MID point of the line is the radius of the quarter circles.

r = 35 cm.

All the 4 QUARTERS circles has the same radius .

Area of the shaded region = Area of square ABCD - Area of 4 quarter circles

= ( Side^2) - ( 4 × Area of a quarter circle)

All quarter circles have same RADII .

= (70^2) - ( 4 × (πr^2/4) )

= 4900 - ( π × (35^2) )

= 4900 - 3848.45

= 1051.55
