A major stadium has 45,000 seats. If baseball fans have bought 5/8 of the seats for the next game, how many seats are available? 3. Draw a picture or a chart that shows the information and the question

Answers

Given:
45,000 seats
5/8 of the seats were bought for the next game.

To get the exact number of seats, we need to multiply the total number of seats by the fraction bought.

45,000 * 5/8 = (45,000 * 5) / 8 = 225,000 / 8 = 28,125 seats

5/8 of the total seats is 28,125 seats which are all unavailable.

8/8 - 5/8 = 8-5/8 = 3/8 is the fraction of the seats available.

45,000 - 28,125 = 16,875 seats available.

45,000 * 3/8 = (45,000 * 3) / 8 = 135,000 / 8 = 16,875

Answer:

A. 16,875

f(x) = x³ - 3x² + 3x - 1f(x + 1) What is the value?

A) x³+1
B) x³-1
C) x³
D) x²
E) x²+1

Answers

$f(x+1)=(x+1)^3-3(x+1)^2+3(x+1)-1\n f(x+1)=x^3+3x^2+3x+1-3(x^2+2x+1)+3x+3-1\n f(x+1)=x^3+3x^2+6x+3-3x^2-6x-3\n f(x+1)=x^3 \Rightarrow C$

f(x)=(x-1)³ = x³ -3x² +3x -1
f(x+1) = (x+1-1)³ = x³
