How do you do the question of 50%of 50 in math like how would you solve it

AveGali [126]

Answer:

Step-by-step explanation:

50% is half of something. half of 50 is 25.

Also there is another way to do it. 50/100 = 50%.

50/100 x 50 = 2500/100 = 25. or 50/100 = 1/2. 1/2 x 50 = 50/2 = 25.

We can find this using the formula for arc length (where $r$ is the radius of the circle and $\theta$ is the central angle in radians):

$\textrm{Arc Length} = r\theta$

In our problem, we are given $12 = 8\theta$ . This means that:

$\theta = \dfrac{12}{8} = \boxed{\frac{3}{2}}$

The measure of the angle is 1.5.

$\displaystyle\\Answer:\ x=\sqrt{2}\ \ \ \ \ x=-\sqrt{2}\ \ \ \ \ x=\frac{ln5}{2}$

Step-by-step explanation:

$5x^2-x^2e^{2x}+2e^{2x}=10$

$Let:\ x^2=t \ \ \ \ \ e^{2x}=v\\Hence,\\5t-tv+2v^2=10\\5t-tv+2v^2-10=10-10\\5t-tv-10+2v^2=0\\t(5-v)-2(5-v)=0\\(5-v)(t-2)=0\\5-v=0\\5-v+v=0+v\\5=v\\5=e^{2x}$

Prologarithmize both parts of the equation:

$ln5=lne^{2x}\\ln5=2x*lne\\ln5=2x*1\\ln5=2x\\$

Divide both parts of the equation by 2:

$\displaystyle\\x=\frac{ln5}{2}$

$t-2=0\\t-2+2=0+2\\t=2\\x^2=2\\x=\sqrt{2} \\x=-\sqrt{2}$
