What is the square root of the number 441? How do you know this and how did you solve this?

nalin [4]

The square root of 441 is 21. for this kind of question you should know 11^2 is 121 so now you should choose a bigger number for 441. it does not have any formula. :))

A circle has a diameter of 2.5 ft.

alukav5142 [94]

A = pi * r^2
D = 2.5 so r = 1.25
A = 3.14 * 1.25^2
A = 4.9 ft^2

What is the first step in solving the quadratic equation x2 = StartFraction 9 Over 16 EndFraction?

dlinn [17]

Step-by-step explanation:

${x}^{2} = \frac{9}{16} \\ first \: step : \: take \: square \: root \: of \: both \\ sides. \\ \sqrt{ {x}^{2} } = \pm \sqrt{\frac{9}{16} } \\ x = \pm \frac{3}{4} \\$

Anyone knowww? :) help!

Yuki888 [10]

The answer would be 17.
This is because, the format for finding out the hypotenuse of a triangle is--
a^2 + b^2 = c^2
So, it would translate to--
15^2 + 8^2 = c^2
225 + 64 = 289
Because 289 = c^2, you need to take the square root of it.
The square root of 289 is 17.
Therefore, your answer is 17.

Ex 4.8 14) integrate 3^(2x-1)

sesenic [268]

Take the integral:

$\large\begin{array}{l} \mathsf{\displaystyle\int\!3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\int\!\frac{1}{2}\cdot 2\cdot 3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^{2x-1}\cdot 2\,dx\qquad(i)} \end{array}$

$\large\begin{array}{l} \textsf{Substitute}\\\\ \mathsf{2x-1=u\quad\Rightarrow\quad 2\,dx=du}\\\\\\ \textsf{so (i) becomes}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^u\,du}\\\\ =\mathsf{\dfrac{1}{2}\cdot \dfrac{1}{\ell n\,3}\,3^u+C}\\\\ =\mathsf{\dfrac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}$

$\large\begin{array}{l} \boxed{\begin{array}{c}\mathsf{\displaystyle\int\!3^{2x-1}\,dx=\frac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}}\qquad\checkmark \end{array}$
