503.782 rounded to the nearest tenth

503.8

Step-by-step explanation:

since 5 - 9 goes up and 1 - 4 goes down you round the 7 to the 8 and make the 7 an 8 and  make all the other numbers a 0 since you rounded up to get 503.80 or just 503.8

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
