Element X decays radioactively with a half life of 9 minutes. If there are 890 grams of Element X, how long, to the nearest tent
elena-s [515]

Answer:

13.18651685

13.9

Explain:

890-238=652
652/890=0.7325842697 (Find out the percentage)

We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.

0.7325842697x18=13.18651685

As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)

And of course we need to round it to nearest tenth. So the answer would be 13.9!

Find the second derivative, do not have to simplify
zlopas [31]

f(x)=\sec(\pi x)=\dfrac{1}{\cos(\pi x)}=[\cos(\pi x)]^{-1}\\\\\text{use}\\\\(a^n)'=na^{n-1}\\\\(\cos x)'=-\sin x\\\\f'(g(x))=f'(g(x))\cdot g'(x)

f'(x)=\left\{[\cos(\pi x)]^{-1}\right\}'=-[\cos(\pi x)]^{-2}\cdot[-\sin(\pi x)]\cdot\pi\\\\=\dfrac{\pi\sin(\pi x)}{[\cos(\pi x)]^2}=\pi\dfrac{\sin(\pi x)}{\cos(\pi x)}\cdot\dfrac{1}{\cos(\pi x)}\\\\=\pi\tan(\pi x)\sec(\pi x)

Solve for x:<br> -3(2x+1) + 3x = 6x + 3<br> Help!!
djverab [1.8K]

Answer:

b  x =-2/3

Step-by-step explanation:

-3(2x+1) + 3x = 6x + 3

Distribute

-6x -3 +3x =6x+3

Combine like terms

-3x-3 = 6x+3

Add 3x to each side

-3x+3x-3 = 6x+3x+3

-3 = 9x+3

Subtract 3 from each side

-3-3 = 9x+3-3

-6 = 9x

Divide by 9

-6/9 = 9x/9

-2/3 =x
