Answer:

C) $122+154i$

Step-by-step explanation:

$(14-2i)(7+12i)\\\\(14)(7)+(14)(12i)+(-2i)(7)+(-2i)(12i)\\\\98+168i-14i-24i^2\\\\98+154i-24(-1)\\\\98+154i+24\\\\122+154i$

Therefore, C is correct. Recall that $i^2=-1$

Q3) f(x) 2x^2 - 5x, g(x) = 3x^3 find g(4x)

mrs_skeptik [129]

Answer:

g(4x) = 192x^3

Step-by-step explanation:

For this problem, f(x) is irrelevant since we are simply are dealing with g(x). We will simply replace the value of x in g(x) with 4x. So let's do that.

g(x) = 3x^3

g(4x) = 3(4x)^3

g(4x) = 3(4^3)(x^3)

g(4x) = 3(64)(x^3)

g(4x) = 192x^3

Hence, g(4x) is 192x^3.

Cheers.

My name is Ann [436]

Answer:

$v = \dfrac{8}{a(y - 7)}$

Step-by-step explanation:

$y = \dfrac{8}{av} + 7$

Subtract 7 from both sides.

$y - 7 = \dfrac{8}{av}$

Multiply both sides by v.

$v(y - 7) = \dfrac{8}{a}$

Multiply both sides by 1/(y - 7).

$v = \dfrac{8}{a(y - 7)}$
