Answer:

T^2*g / 4pi^2  = l

Step-by-step explanation:

T = 2 * pi * sqrt( l/g)

We need to solve for l

Divide each side by 2pi

T/ (2pi) = 2 * pi/2pi * sqrt( l/g)

T/ (2pi) =  sqrt( l/g)

Now square each side

(T/ (2pi))^2 = ( sqrt( l/g))^2

T^2 / 4pi^2 = l/g

Multiply each side by g

T^2 / 4pi^2  * g= l/g*g

T^2*g / 4pi^2  = l

Can someone plz help me with this problem and plz show work.

Answer:

C

Step-by-step explanation:

y = 2x + 5

the slope (m) of this line is 2 (which can be written as 2/1)

The slope of a perpendicular line is -1/m (the reciprocal of the slope with the opposite sign)

so m = 2/1 => -1/m = - 1/2 = the slope of a line perpendicular to y = 2x + 5

Explain what can happen if you line up the digits incorrectly when you rewrite additional problem
Natasha_Volkova [10]
So basiclly you will end up getting the wrong answer. For example 234+23.
If you lined it up incorrectly you might get 464. It is actually 257. This is wy you should line it up correctly.
