Answer:
Below in bold.
Step-by-step explanation:
f(x) = x(18x + 4)
f(x) = 18x^2 + 4x
Antiderivative = 18 * (x^2+1)/(2 + 1) -+4x(1+1) / (1+1) + C
= 18x^3 / 3 + 4x^2 / 2 + C
= 6x^3 + 2x^2 + C.
Checking by differentiating:
f'(x) = 6*3 x^(3-1) + 2*2x^(2-1)
= 18x^2 + 4x
= x(18 -+4)
Answer: 56
Step-by-step explanation:
You would set up equations for both the member and the non-member.
The member's equation would be: 384+8x (x being the number of rounds)
The non-member's equation would be: 48x+24x
then you would set them equal to each other and then solve:
384+8x=48x+24x
384=64x
384/64=x
x=6
they would have to play 6 rounds in order to pay the same amount.
10 bronze medals
explaining:
if 3 of the medals were gold there would be 15 left. Since there was twice as many bronze from silver they would have 5 silver medals and 10 bronze.
