Answer:

A. 282

Step-by-step explanation:

A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.

282:

2 + 8 + 2 = 12

187:

1 + 8 + 7 = 16

385:

3 + 8 + 5 = 16

412:

4 + 1 + 2 = 7

The Decimal System Uses 10 Symbols To Represent Numbers True or false​
lutik1710 [3]

Answer:

For non-negative integers yes, it's 10 symbols.

Step-by-step explanation:

The symbols are the digits! 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Please note, that to represent negative numbers we use an additional symbol - and a . for fractions. I'm pretty sure the question is about the basics of the decimal system and the ten digits though.

romanna [79]

Answer:

\frac{2}{x^4}


Step-by-step explanation:

The expression is 2x^{-4}

<u>We use the rule of exponents shown below to change the original to </u><u>"positive"</u><u> exponent form:</u>

<u>a^-b=\frac{1}{a^b}</u>


<em>Now we can change the original expression given into positive exponent:</em>

2x^{-4}\\=\frac{2}{x^4}

Let f(x)=(8x^4-3)^3 and g(x)=8x^4-3 given that f(x)=(h g)(x) , find h(x)
Harman [31]

<u>Answer:</u>

h(x) = x^{3}

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

f(x) = (8 \times x^{4}- 3)^{3} ------------(1) (given)

g(x) =(8 \times x^{4}- 3) -------------(2) (given)

so,

f(x) = h(g(x)) (given)

    = (g(x))^{3}-----(from (1) and (2))

⇒h(k) = k^{3}-----(taking g(x) = k)

⇒h(x) = x^{3} is the function.
