<u>Answer:</u>
The point-slope equation of the line is or
<u>Solution:
</u>
Let us assume that the slope is m and the y intercept of the line is b
Hence, --------- (i)
y intercept means we need to find the value of y when x is 0
Here the line passes through point (4,-6) and slope m = (-2)
Now putting the point (4,-6) in equation (i) we get,
So, the equation of the line will be will be or
There are 72 tens in 720.
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
