Use half the fencing in each direction: 3 segments in one direction, 2 in the other.
<span>W * L = 24 million </span>
<span>3 W = 2 L </span>
<span>W * 3 W / 2 = 24 million </span>
<span>W^2 = 16 million </span>
<span>W = 4000 </span>
<span>L = 6000 </span>
<span>This shortcut (3 W = 2 L) </span>
<span>is derived from total fencing = 3W + 2L </span>
<span>and W*L = 24 million </span>
<span>total fencing = 3W + 2 * 24 million / W </span>
<span>and taking the derivative, setting to 0, and solving for W</span>
I'll do the first one to get you started
So we have g(f(x)) which means that we start with g(x) and replace the 'x' with 'f(x)' to get g(f(x))
g(x) = ( x - 4 )/2
g(f(x)) = ( f(x) - 4)/2 .... replace every x with f(x)
g(f(x)) = (2x+4-4)/2 .... replace f(x) on the right side with 2x+4
g(f(x)) = (2x+0)/2
g(f(x)) = (2x)/2
g(f(x)) = 1x/1
g(f(x)) = 1x
g(f(x)) = x
Let me know if you need help with the other one.
The answer is 108 because the angle is obtuse which is greater than 90.
Answer:
j3a3
Step-by-step explanation:
Here's the equation for one year:
1000 + 0.08(1000)
But because it is 9 years:
1000 + 9(0.08(1000))
1000 + 0.72(1000)
We can make it simpler:
1.72(1000)
Multiply:
1720
You will have $1720
