Value of {tex}\frac{x}{\sqrt{a^2+x^2}}{/tex}
{tex}\tan \theta=\frac{\mathrm{a}}{\mathrm{x}} Since, \begin{aligned} & \frac{x}{\sqrt{a^2+x^2}} \\ & \Rightarrow \frac{\frac{a}{\tan \theta}}{\sqrt{a^2+\left(\frac{a}{\tan \theta}\right)^2}} \\ & \Rightarrow \frac{\frac{a}{\tan \theta}}{\sqrt{a^2+\frac{a^2}{\tan ^2 \theta}}} \end{aligned} {/tex}
{tex}\begin{aligned} & \Rightarrow \frac{\frac{a}{\tan \theta}}{a \sqrt{\frac{1+\tan ^2 \theta}{\tan ^2 \theta}}} \\ & \Rightarrow \frac{\frac{1}{\tan \theta}}{\sqrt{\frac{1+\tan ^2 \theta}{\tan ^2 \theta}}} \\ & \Rightarrow \frac{1}{\sqrt{\sec ^2 \theta}} \\ & \Rightarrow \frac{1}{\sec \theta} \end{aligned}{/tex}
{tex}\Rightarrow \cos \theta {/tex}

- Vegetative propagated plants are short lived, small compared to seed propagated plants.
- No new varieties can be produced.
- Skilled persons are required and often expensive compared to seed propagation.
- More susceptible to diseases as the entire plant may get affected as there is no genetic variation.

किसी पात्र में थोड़ा पानी ले कर उबलने के लिए ऑच पर रखने से, पात्र की तली में नन्हे बुदबुदे दिखाई देने लगते हैं। ये पानी में घुली हुई वायु के अलग हो कर भाप बनने के संकेत हैं। पानी उबलने की स्थिति में बड़े बड़े भाप के बबूले उपर तक आ जाते है और हवा में घुल जाते हैं । इस से पता लगता है कि जल में वायु घुली होती है ।

Given quadratic equation is p(x-4)(x-2)+(x-1)² = 0
=> p(x²-4x-2x+8)+(x²-2x+1) = 0
=> p(x²-6x+8)+(x²-2x+1) = 0
=> px²-6px+8p+x²-2x+1 = 0
=> (px²+x²)+(-6px-2x)+8p+1 = 0
=> (p+1)x²-(6p+2)x+(8p+1) = 0
On comparing with the standard quadratic equation is ax²+bx+c = 0 then
a = p+1
b = -(6p+2)
c = 8p+1
Given that
Given equation has real and equal roots
=> The discriminant = 0
We know that
The discriminant of ax²+bx+c = 0 is b²-4ac
Therefore, b²-4ac = 0
=> [-(6p+2)]²-4(p+1)(8p+1) = 0
=> (6p+2)²-4(p+1)(8p+1) = 0
=> (36p²+24p+4)-4(8p²+p+8p+1) = 0
=> (36p²+24p+4)-4(8p²+9p+1) = 0
=> 36p²+24p+4-32p²-36p-4 = 0
=> (36p²-32p²)+(24p-36p)+(4-4) = 0
=> 4p² -12p+0 = 0
=> 4p² - 12 p = 0
=> 4p(p-3) = 0
=> 4p = 0 or p-3 = 0
=> p = 0/4 or p = 3
=> p = 0 or p = 3
If p = 0 the term containing p doesn't exist .
Therefore, p = 3
