Polynomials please someone help me !!! (x4)2

I strongly believe you meant (x^4)^2 as you're referring to polynomials.

(x^4)^2

= (x^4)*(x^4)

= (x*x*x*x)*(x*x*x*x)

<span>= x^8</span>

On the other hand, if you meant (x^4)2, then the answer is 2x^4

Hope this helps! :3

Remember
(x^n)^m=x^(mn)

(x^4)^2=x^(4*2)=x^8

Help pleaseeeeeeeeee

Answer:

39°
27°
28°

Step-by-step explanation:

$Hypotenuse = 32\\Adjacent = 25\\Angle\:\alpha \:=?\\Using \: SOHCAHTOA ;\\Cos \:\alpha = \frac{adj}{hyp} \\Cos \:\alpha = \frac{25}{32}\\\\\alpha = Cos^-^1\frac{25}{32} \\\alpha =38.62\\\\\alpha = 39$

$Opposite = 8\\Adjacent = 16\\\alpha =?\\Using SOHCAHTOA\\Tan\:\alpha = \frac{opp}{adj} \\Tan\:\alpha = \frac{8}{16} \\Tan \:\alpha =1/2\\\alpha = Tan^-^11/2\\\\\alpha =26.56\\\alpha =27$

$Hypotenuse = 41\\Opposite = 19\\\alpha = ?\\Using\: SOHCAHTOA\\Sin\:\alpha = \frac{opp}{hyp} \\Sin \:\alpha =\frac{19}{41}\\\\\alpha =Sin^-^1 (19/41)\\\\\alpha =27.6\\ \alpha =28$

Solve and check: 3 x2 + 5x + 6 + x − 1 x + 2 = 7 x + 3

vagabundo [1.1K]

Answer:

3 $x^{2}$ -2x +5=0

Step-by-step explanation:

Combine liked terms:

3 $x^{2}$ +5x+x-1x+6+2=7x+3

3 $x^{2}$ +6x-1x+8=7x+3

3 $x^{2}$ +5x+8=7x+3

Subtract 3: 3 $x^{2}$ +5x+8-3=7x+3-3

3 $x^{2}$ +5x+5=7x

Now subtract 7x:

3 $x^{2}$ +5x+5-7x=7x-7x

If you want combine liked terms:

3 $x^{2}$ -7x+5x+5=0

3 $x^{2}$ -2x+5=0

Hope this helps!

Your personal library contains books written by 165 authors. 60% of the authors are men. 40% of the authors write only nonfictio

Ludmilka [50]

Lets discern the infomation:

number_men = 165*0.6 = 99

so there are 99 men

non_fiction = 165 * 0.4 = 66

so 66 authors write non-fiction.

men writing non-fiction are 40, so 59 men write fiction, and 26 women write non-fiction.

probability of author non-fiction or man?
non-fiction: 40 men + 26 women = 66 total
man writers = 99

so in total 99 man + 26 women = 115 authors

hence the probability is:
115/165 = 69.6%
