Answer:
f(6) ≈ 31
Step-by-step explanation:
If f(x) varies directly with x, we can write f(x) this way:
f(x) = kx
Using the given values, we can find k:
f(25) = k×25 = 130
k = 130/25 = 5.2
Then for x = 6, we have ...
f(x) = 5.2x
f(6) = 5.2×6 = 31.2
Rounded to the nearest whole number, ...
f(6) ≈ 31
(f.g)(x) = f (g(x))= f ( x^4+3)
= (x^4+3)^2 + 2 ( x^4+3) - 6
= x^8 + 9 + 6x^4 + 2x^4 + 6-6
= x^8 + 8x^4+9
Answer:
4,810
Step-by-step explanation:
$10 per ticket times 741 people (10 * 741) is 7,410, then subtract the cost to produce the play, 7,410 - 2600 = 4,810.
