<span>f(t) = 94*1.25992105^t
Since the value doubles every three years we want an X such that
X^3 = 2
Or in simpler terms, our growth rate is the cube root of 2. So lets get that. To calculate the nth root of a number you can take the logarithm of the number, divide by n, then get the anti-log. So
10^(log(2)/3) = 10^(0.301029996/3) = 10^0.100343332 = 1.25992105
Now the function becomes trivial. I'll use t as the number of years since the baseline capacity was calculated (94 thousand megawatts at t = 0). So
f(t) = 94*1.25992105^t</span>
Answer:
29
Step-by-step explanation:
if you do 58 divided by 2 you get 29 so Mr. John doubles 29.
We know that
The formula to <span>find the sum of the interior angles of a regular polygon is
</span>(n - 2)*180°
where n is the number of sides
so
clear n
(n - 2)*180° = 720°-----> (n-2)=720/180---> n-2=4----> n=6 sides
the answer is
6 sides
You can do pictures like just say six pig + seven pigs = 13 pigs...Hope that helps
![(g-f)(x) = -x^2-5x-5](https://tex.z-dn.net/?f=%28g-f%29%28x%29%20%3D%20-x%5E2-5x-5)
Step-by-step explanation:
Given functions are:
![f(x) = x^2+6x-2\\g(x) = x-7\\h(x) = x+4](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%2B6x-2%5C%5Cg%28x%29%20%3D%20x-7%5C%5Ch%28x%29%20%3D%20x%2B4)
The operations on functions can be performed just as they are performed on polynomials
So
![(g-f)(x)=g(x)-f(x)\\=(x-7)-(x^2+6x-2)\\=x-7-x^2-6x+2\\](https://tex.z-dn.net/?f=%28g-f%29%28x%29%3Dg%28x%29-f%28x%29%5C%5C%3D%28x-7%29-%28x%5E2%2B6x-2%29%5C%5C%3Dx-7-x%5E2-6x%2B2%5C%5C)
Combining like terms
![=-x^2+x-6x-7+2\\=-x^2-5x-5](https://tex.z-dn.net/?f=%3D-x%5E2%2Bx-6x-7%2B2%5C%5C%3D-x%5E2-5x-5)
Hence,
![(g-f)(x) = -x^2-5x-5](https://tex.z-dn.net/?f=%28g-f%29%28x%29%20%3D%20-x%5E2-5x-5)
