Answer:
9/16 students got a book.
Step-by-step explanation:
Number of students who went to book fair: 15/20 = 3/4
Number of students who got a book: 12/16 = 3/4
(3/4)*(3/4) = 9/16
Answer:
x = -1/4 + sqrt(47)/4 i , -1/4 - sqrt(47)/4 i
Step-by-step explanation:
2x^2+x+6=0
using the quadratic formula
-b ±sqrt(b^2 -4ac)
--------------------------
2a
-1 ±sqrt(1 -4(2)(6))
--------------------------
2(2)
-1 ±sqrt( 1 - 48)
------------------
4
-1 ± sqrt(-47)
-------------
4
-1 ± sqrt(-1) sqrt(47)
-------------------------
4
remember sqrt(-1) = i
-1 ± i sqrt(47)
----------------
4
x = -1/4 + sqrt(47)/4 i , -1/4 - sqrt(47)/4 i
Answer:
40
Step-by-step explanation:
f(n) = 5 + (n - 1)(5)
f(n) = 5 + 5n - 5
f(n) = 5n
n = 8
5(8) = 40
It would be d Answer if you simplified it
Three zeros will be the product
