Answer:

7 inches

Step-by-step explanation:

Using Pythagoras' theorem on the right triangle, that is

r² + 11² = 13²

r² + 121 = 169 ( subtract 121 from both sides )

r² = 48 ( take the square root of both sides )

r = $\sqrt{48}$ ≈ 7 in ( to the nearest inch )

Let f(x) = -4x + 7 and g(x) = 10x - 6. Find f(g(x)).

Triss [41]

$f(x)=-4x+7\\
g(x)=10x-6\\\\\Substitute\ x=10x-6\ to\ f(x)\\
f(g(x))=-4(10x-6)+7\\
f(g(x))=-40x+24+7=-40x+31\\\\\
Solution\ is\ f(g(x))=-40x+31.$

Answer:

f(g(h(x))) = (sqrt(x) - 1)^4 + 4

Step-by-step explanation:

f(x) = x^4 + 4

g(x) = x - 1

h(x) = sqrt(x)

g(h(x)) = sqrt(x) - 1

f(g(h(x))) = (sqrt(x) - 1)^4 + 4
