Answer» ong>GIVEN :- roots of quadratic EQUATION are 3/4 and -2/3. TO FIND :- The quadratic equation by the GIVEN roots SOLUTION :- As we KNOW that the quadratic equation is given by, $\\ : \implies \displaystyle \sf \:x^{2} - ( \alpha + \beta )x + ( \alpha \beta ) = 0\\ \\$ α = 3/4. β = -2/3 Now, by SUBSTITUTING the values we get, $\\ : \implies \displaystyle \sf \:x^{2} - \bigg( \frac{3}{4} - \frac{2}{3} \bigg)x + \bigg( \frac{3}{4} \times \frac{ - 2}{3} \bigg)= 0 \\ \\ \\$ $: \implies \displaystyle \sf \:x^{2} - \bigg( \frac{9 - 8}{12} \bigg)x + \bigg( \frac{ - 2}{4} \bigg) = 0 \\ \\ \\$ $: \implies \displaystyle \sf \:x^{2} - \frac{1}{12} x + \bigg( \frac{ - 1}{2} \bigg) = 0 \\ \\ \\$ $: \implies \underline{ \boxed{ \displaystyle \sf \bold{ \:x^{2} - \frac{1}{12} x - \frac{1}{2} = 0}}} \\ \\$ Hence the required quadratic equation is $\displaystyle \sf x^{2} - \frac{1}{12} x - \frac{1}{2} = 0$

22.

From quadratic equation whose roots are 3/4and -2/3

Answer»

ong>GIVEN :-

roots of quadratic EQUATION are 3/4 and -2/3.

TO FIND :-

The quadratic equation by the GIVEN roots

SOLUTION :-

As we KNOW that the quadratic equation is given by,

$\\ : \implies \displaystyle \sf \:x^{2} - ( \alpha + \beta )x + ( \alpha \beta ) = 0\\ \\$

α = 3/4.
β = -2/3

Now, by SUBSTITUTING the values we get,

$\\ : \implies \displaystyle \sf \:x^{2} - \bigg( \frac{3}{4} - \frac{2}{3} \bigg)x + \bigg( \frac{3}{4} \times \frac{ - 2}{3} \bigg)= 0 \\ \\ \\$

$: \implies \displaystyle \sf \:x^{2} - \bigg( \frac{9 - 8}{12} \bigg)x + \bigg( \frac{ - 2}{4} \bigg) = 0 \\ \\ \\$

$: \implies \displaystyle \sf \:x^{2} - \frac{1}{12} x + \bigg( \frac{ - 1}{2} \bigg) = 0 \\ \\ \\$

$: \implies \underline{ \boxed{ \displaystyle \sf \bold{ \:x^{2} - \frac{1}{12} x - \frac{1}{2} = 0}}} \\ \\$

Hence the required quadratic equation is $\displaystyle \sf x^{2} - \frac{1}{12} x - \frac{1}{2} = 0$

42.

In order to move a 10kg object fromconstant force of 4N is appliedfor 4 minutes Calculate the velocity ofobject at the end of 4 minutes.

Answer»

ong>Answer:

v = 400 m/s

Step-by-step explanation:

To find - v (FINAL velocity)

Given :-

Mass of object - 10 kg
Constant force APPLIED - 4 N

= 4 kgm/s²

Force applied for - 4 min

= 240 s

Now,

F = ma

a = F/m

= 4 kgm/s² / 10 kg

= 2/5 m/s²

We can find 'v' by using 1st EQ. of motion,

v = u + at

Initial velocity (u) = 0 m/s

Therefore,

v = 0 + (5/3 m/s²) × (240 s)

v = 400 m/s

1−2isinθ

3+2isinθ

=

(1+2isinθ)(1−2isinθ)

(3+2isinθ)(1+2isinθ)

=
