5 kg is more precise because if you said 5212 g, they will be trying to see what the precise answer is so if you say 5 kg that will save all of the work.
P.S.: its not 5212 g, its 5000 g. :)
Answer:
James is 58 and Tyson is 39 years old.
Step-by-step explanation:
x + y = 97
x - y = 19 +
--------------
2x = 116
x = 58
--------------
y = 97 - 58
y = 39
The value of f(-6) is -12.2
Explanation:
Given that the function ![f(x)=\frac{100}{-10+e^{-0.1\left(x\right)}}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B100%7D%7B-10%2Be%5E%7B-0.1%5Cleft%28x%5Cright%29%7D%7D)
We need to determine the value of f(-6)
The value of f(-6) can be determined by substituting the value for
in the function and simplify the function.
Hence, let us substitute
in the function, we get,
![f(-6)=\frac{100}{-10+e^{-0.1\left(-6\right)}}](https://tex.z-dn.net/?f=f%28-6%29%3D%5Cfrac%7B100%7D%7B-10%2Be%5E%7B-0.1%5Cleft%28-6%5Cright%29%7D%7D)
Let us apply the rule
, we get,
![f(-6)=\frac{100}{-10+e^{0.1\left(6\right)}}](https://tex.z-dn.net/?f=f%28-6%29%3D%5Cfrac%7B100%7D%7B-10%2Be%5E%7B0.1%5Cleft%286%5Cright%29%7D%7D)
Multiplying the numbers, we get,
![f(-6)=\frac{100}{-10+e^{0.6}}](https://tex.z-dn.net/?f=f%28-6%29%3D%5Cfrac%7B100%7D%7B-10%2Be%5E%7B0.6%7D%7D)
The value of ![e^{0.6}=1.822](https://tex.z-dn.net/?f=e%5E%7B0.6%7D%3D1.822)
Substituting the value of
, we get,
![f(-6)=\frac{100}{-10+1.822}](https://tex.z-dn.net/?f=f%28-6%29%3D%5Cfrac%7B100%7D%7B-10%2B1.822%7D)
Subtracting the denominator, we have,
![f(-6)=\frac{100}{-8.178}](https://tex.z-dn.net/?f=f%28-6%29%3D%5Cfrac%7B100%7D%7B-8.178%7D)
Dividing, we have,
![f(-6)=-12.228](https://tex.z-dn.net/?f=f%28-6%29%3D-12.228)
Rounding off to the nearest tenth, we have,
![f(-6)=-12.2](https://tex.z-dn.net/?f=f%28-6%29%3D-12.2)
Thus, the value of f(-6) is -12.2
