Answer:
22.8
Step-by-step explanation:
The unit rate for this problem is 1/3.80 (the bottle of syrup to the cost). So if there are 6 pumps, then we have to multiply 3.80 by 6, which is 22.80.
also, if one bottle is 25.4 oz, to get the amount of oz for 6 bottles, we multiply 25.4 by 6 which is 152.4 oz.
Hope I helped!! :D
But if I'm wrong I am sorry.
Answer: 67.5
Step-by-step explanation:
Given: The mass of drug = 450 mg
The mass percent error = 15%
Which can be written as 0.15.
We use the formula :-
![\text{Error}=\text{Previous value }\times\text{Percent error}](https://tex.z-dn.net/?f=%5Ctext%7BError%7D%3D%5Ctext%7BPrevious%20value%20%7D%5Ctimes%5Ctext%7BPercent%20error%7D)
Similarly, ![\text{Mass Error}=\text{Mass of drug }\times\text{Mass percent error}](https://tex.z-dn.net/?f=%5Ctext%7BMass%20Error%7D%3D%5Ctext%7BMass%20of%20drug%20%7D%5Ctimes%5Ctext%7BMass%20percent%20error%7D)
![\Rightarrow\ \text{Mass Error}=450\times0.15=67.5\ mg](https://tex.z-dn.net/?f=%5CRightarrow%5C%20%5Ctext%7BMass%20Error%7D%3D450%5Ctimes0.15%3D67.5%5C%20mg)
Hence, the mass error would be 67.5 mg.
u = 1+3e<span>-x</span>
so that (Don't forget to use the chain rule on e<span>-x</span>.)
du = 3e<span>-x</span>(-1) dx = -3e<span>-x</span> dx ,
or
(-1/3)du = e<span>-x</span> dx .
However, how can we replace the term e<span>-3x</span> in the original problem ? Note that
.
From the u-substitution
u = 1+3e<span>-x</span> ,
we can "back substitute" with
e<span>-x</span> = (1/3)(u-1) .
Substitute into the original problem, replacing all forms of x, getting
(Recall that (AB)C = AC BC .)
Answer:
