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
If x is 100-26
x=74
So
The square root of 7+ x is
Answer:
A1.) 87 + 63 =150
180 - 150 = 30
all the As is the same formula....
B1.) 180 - 123 = 57
57 + 82 = 139
180 - 131 = 41
4x-2y=8
x-3y=-3
Multiply equation 2 by 4;
4x-2y=8
4x-12y=-12
Subtracting equation II from equation I;
10y=20
y=2
Replacing the value of y in equation;
4x-2y=8
4x-2(2)=8
4x-4=8
4x=12
x=3
x=0 and y=
Step-by-step explanation:
We need to solve the system by elimination and find values of x and y

Subtract eq(1) and eq(2)

Now Multiply equation (1) by 2 and subtract with eq(2)

So, x=0 and y=
