A + b = 42
a - b = 16 ==> a = b + 16

b + 16 + b = 42
2b + 16 = 42
2b = 42 - 16
2b = 26
b = 26/2
b = 13 <===

a = b + 16
a = 13 + 16
a = 29 <===

Find the limit. use l'hospital's rule if appropriate. if there is a more elementary method, consider using it. lim x→1 1 − x + l
AfilCa [17]

\displaystyle\lim_{x\to1}\frac{1-x+\ln x}{1+\cos5\pi x}

Evaluating the limand directly at x=1 gives an indeterminate form \dfrac00. Apply L'Hospital's rule once and we get

\displaystyle\lim_{x\to1}\frac{-1+\frac1x}{-5\pi\sin5\pi x}

Again, plugging in x=1 returns \dfrac00. Apply the rule once more:

\displaystyle\lim_{x\to1}\frac{-\frac1{x^2}}{-25\pi^2\cos5\pi x}=\frac1{25\pi^2}\lim_{x\to1}\frac1{x^2\cos5\pi x}

Now, in the denominator, when x=1 we get x^2\cos5\pi x=-1, so the limit is -\dfrac1{25\pi^2}.

What is 11/4-3/8= what is it or get me the right answer
likoan [24]

Answer:

2 3/8 is the answer

Step-by-step explanation:

11/4 - 3/8

We will find the LCM of 4 and 8, which is 8.

We will do 11/4*8, which 8/4 = 2 and 2*11 = 22

Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3

So the answer will be <u>22-3 </u> =  19

                                        8     =   8

Mixed Fraction = 2 3/8
