Answer:

<h2>(h + k)(2) = 5</h2>

Step-by-step explanation:

(h+k)(x)=h(x)+k(x)\\\\\bold{METHOD\ 1:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(k+h)(2)=h(2)+k(2)\\\\\text{Calculate}\ h(2)\ \text{and}\ k(2).\\\text{Put}\ x=2\ \text{to the equations of the functions}\\\\h(2)=2^2+1=4+1=5\\k(2)=2-2=0\\\\\text\\\\\text{Substitute:}\\\\(h+k)(2)=5+0=5

\bold{METHOD\ 2:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(h+k)(x)=h(x)+k(x)=(x^2+1)+(x-2)=x^2+x-1\\\\(h+k)(2)-\text{put}\ x=2\\\\(h+k)(2)=2^2+2-1=4+2-1=6-1=5

marin [14]
The half-life is 29 years.
116 : 29 = 4
So we will have 4 periods of half-life:
( 1/2 )^4 = 1/16
150 g * 1/16 = 9.375 g
Answer:
9.375 g of strontium -90 will remain after 116 years.

The value of 8⁴ is 8 * 8 * 8 * 8 = 4,096 CHOICE C.

Prime factorization of 1,260

1260 ÷ 2 = 630
  630 ÷ 2 = 315
  315 ÷ 3 = 105
  105 ÷ 3 =  35
    35 ÷ 5 =    7

2 x 2 x 3 x 3 x 5 x 7 CHOICE D.

Composite numbers are numbers that have more factors other than 1 and itself.

91 / 1 = 91
91 / 7 = 13      CHOICE C. 91 is a composite number.
