Which statements are true?<br>(look at picture)

Makovka662 [10]

Answer:

D is true, E is true, F is true

Step-by-step explanation:

Hello,

n is an odd number it means that n = 2a+1 where a is integer

A

$n^2-1=(2a+1)^2-1=4a^2+4a+1-1=4a(a+1)$

this is <u>not</u> an odd number

B

$n(n-1)=(2a+1)2a$

this is <u>not</u> an odd number

C

$(n-1)^2=(2a+1-1)^2=4a^2$

this is <u>not</u> an odd number

D

$n^2+2=(2a+1)^2+2=4a^2+4a+1+2=4a^2+4a+3= 2(2a^2+2a+1)+1$

so this is an odd number

E

$n(n-2)=(2a+1)(2a-1)=4a^2-1=4a^2-2+1=2(2a^2-1)+1$

so this is an odd number

F

$(n-2)^2=(2a+1-2)^2=(2a-1)^2=4a^2-4a+1 = 2(2a^2-2a)+1$

this is an odd number

hope this helps

Simplify h(w)=6*2^(w-1)<br><br>Answer:<br>㏒₂(hw/6)=w-1

Alex73 [517]

Answer: log₂ $(\frac{h(n)}{6})$ + 1 = n

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

h(n) = 6 * 2ⁿ⁻¹

<u> ÷6 </u> <u>÷6 </u>

$\frac{h(n)}{6}$ = 2ⁿ⁻¹

log₂ $(\frac{h(n)}{6})$ = log₂(2ⁿ⁻¹) →→<em>log₂2 cancels out</em>

log₂ $(\frac{h(n)}{6})$ = n - 1

log₂ $(\frac{h(n)}{6})+1$ = n
