Answer:
x = 1/2 ± √2 / 2
Step-by-step explanation:
4x²-4x-1=0
Roots: x = (-b ± √b² - 4ac) / 2a a=4 b=-4 c=-1
x = (- -4 ± √(-4)² - 4*4*(-1)) / 2*4
x = (4 ± √32) / 8 = (4 ± 4√2) / 8 = 1/2 ± √2 / 2
Oh goodness i have no clue
Answer:
37 buses and 1 van.
Step-by-step explanation:
The cost to rent a van is $1200 for 50 students and 3 chaperones, while a bus for 10 students and a chaperone is $100 .
The cost of renting buses for 50 students is $500
What we do is rent 37 buses and 1 van
37 buses will take in 370 students with empty 2 spaces in 2 buses for chaperones since the chaperones are 36.
Then rent 1 van to take in 50 students and 1 chaperone.
The total cost here will be
$3700 + $1200 = $ 4900
This will help to safe cost.
