Tell whether the statement is true or false. {4, 10, 15} = {0, 4, 10, 15}

1 answer:

5 0

0 is contained in the set {0, 4, 10, 15}, but 0 is not the element of {4, 10, 15}.

Therefore, the statement is false.

Let f(x) = 3x + 2 and g(x) =7x + 6. Find f ·g and its domain.

Kitty [74]

Answer:

The answer is the option D

$21x^{2}+32x+12$ ; All real numbers

Step-by-step explanation:

we have

$f(x) = 3x + 2$

$g(x) =7x + 6$

Calculate f(x)*g(x)

$(3x + 2)*(7x+6)$

Multiply applying the distributive property

$(3x + 2)*(7x+6)=3x*7x+3x*6+2*7x+2*6\\=21x^{2}+18x+14x+12\\=21x^{2}+32x+12$

The domain of the function is the interval------> (-∞,∞)

All real numbers

yuradex [85]

Answer:

$a = \sqrt{21}$

Step-by-step explanation:

Pythagorean theorem
$\sqrt{a ^{2} + b ^{2} } = c \\ \sqrt{c ^{2} - b ^{2} } = a$
$\sqrt{5 ^{2} - 2 ^{2} } = \sqrt{21}$
