Answer:
450
Step-by-step explanation:
If 81 is 18% of a number then we can say that:
x × 0.18 = 81
We multiply by 0.18 because 18% is 0.18 as a decimal. So to work out the real number we divide 81 by 0.18:
81 ÷ 0.18 = 450
![x(t)=\int_0^6(2*e^ \frac{t}{2}-6})\ dt=\left[4*e^ \frac{t}{2}-6t\right]_0^6\\\\ =e^3-36-4=4e^3-40\approx{40.3421...}\\\\](https://tex.z-dn.net/?f=x%28t%29%3D%5Cint_0%5E6%282%2Ae%5E%20%5Cfrac%7Bt%7D%7B2%7D-6%7D%29%5C%20dt%3D%5Cleft%5B4%2Ae%5E%20%5Cfrac%7Bt%7D%7B2%7D-6t%5Cright%5D_0%5E6%5C%5C%5C%5C%20%3De%5E3-36-4%3D4e%5E3-40%5Capprox%7B40.3421...%7D%5C%5C%5C%5C)
