How do you find the square roots of fractions. For example the square root of 9 over 16?

1 answer:

8 0

For the square root of a fraction, you could divide the fraction (top divided by the bottom) and then find the square root of the quotient. 9 divided by 16 is 0.5625, and the square root of 0.5625 is 0.75. / / / / For the other way to do it, you have to know that the square root of a fraction is the same thing as the square root of the top over the square root of the bottom. So the sqrt (9/16) = sqrt (9)/sqrt (16) = 3/4. (same thing as 0.75 .)

Find the second derivative y= x^2lnx

Dimas [21]

First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx

now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
1+2+2lnx
3+2lnx is the answer

Please help it's urgent.

arlik [135]

Answer:

It is the second triangle.

Step-by-step explanation:

This is because the area of the square is given as 25^2 as the perpendicular, 144^2 as the base, and the hypotenuse is 169^2.

Length of the perpendicular = 5^2 (Because 25^2 / 5^2)

Length of the base = 12^2

Length of the hypotenuse = 13^2

So, the Pythagoras theorem is,

=> $H^{2} = P^{2} + B^{2}$

=> $13^{2} =12^{2} +5^{2}$

This is true, because, 13*13 = 12*12 + 5*5

=> 169 = 144 + 25

=> 169 = 169

If my answer helped, kindly mark me as the brainliest!!

Thanks!!
