Find the greatest possible error for each measurement.<br> 10 1/8 oz
scoray [572]

<u>Answer:</u>

0.0005 oz

<u>Step-by-step explanation:</u>

Usually, the greatest number that is allowed for approximation, assuming that the number itself is obtained by approximation, is the greatest possible error of it.

It is normally half the place value of the last digit in a number.

Like here we have 10\frac{1}{8} oz which is equal to 10.125 oz. The last digit is 5 which is at the thousandth place (0.001) so the greatest possible error for this would be its half.

\frac{0.001}{2} = 0.0005 oz

Differentiate the function. f(x) = sin(9 ln(x))
gayaneshka [121]

Answer: f'(x)=\dfrac{9\cos(9\ln (x))}{x}.

Step-by-step explanation:

The given function is

f(x)=\sin(9\ln (x))

Using chain rule differentiate w.r.t. x.

f'(x)=\cos(9\ln (x))\dfrac{d}{dx}(9\ln (x))      \left[\because \dfrac{d}{dx}\sin x=\cos x\right]

f'(x)=\cos(9\ln (x))\left[9\dfrac{d}{dx}(\ln (x))\right]

f'(x)=\cos(9\ln (x))\left[9\times \dfrac{1}{x}\right]       \left[\because \dfrac{d}{dx}\ln x=\dfrac{1}{x}\right]

f'(x)=\dfrac{9\cos(9\ln (x))}{x}

Therefore, f'(x)=\dfrac{9\cos(9\ln (x))}{x}.

The weight of an elephant is 10 time power of 3 the weight of a cat. If the elephant weighs 14,000 pounds, how many pounds does
Keith_Richards [23]
The weight of the cat is 14 pounds. I found my answer by reading the 10 time power of 3, which I know is 1,000. Then, I got 14,000 divide by 1,000, and I got 14.
