Which of these is the composite function f(g(x))? f(x) = x2 – 5 g(x) = 9x – 2

1 answer:

7 0

$f(x)=x^2-5\\\\g(x)=9x-2\\\\\\f(g(x))=\big(9x-2\big)^2-5=81x^2-2\cdot9x\cdot2+4-5=\boxed{81x^2-36x-1}$

Answer:

The parametrization, of the given curve is $x = 10 cos(t) \ \ ,z = 10 sin(t)$

Step-by-step explanation:

From the question we are given the function

$x^2 + y^2 + z^2 = 125$

At y= 5

$x^2 + 5^2 +z^2 =125$

$x^2 + z^2 = 100$

$x^2 + z^2 = 10^2$

Converting the above to it polar equation we have

$x = 10 cos(t) \ \ ,z = 10 sin(t)$
