Answer:
The exponents of a start at n and decrease until they reach 0 . The exponents of b start at 0 and increase until they reach n
Step-by-step explanation:
The general formula for 
is:
Therefore, the exponents of a start at n and decrease until they reach 0 . The exponents of b start at 0 and increase until they reach n
Answer: 81. If you subtract 10% from the amount of 90, you get 81.
Answer:
5.8 is bigger
Step-by-step explanation:
a = 30
a = 16
-a² + 46a -480 = 0
(-a + 30) (a -16) = 0
(-a)(a) + (-a)(-16) + 30(a) + 30(-16) = 0
-a² + 16a + 30a -480 = 0
-a² + 46a - 480 = 0
(-a + 30) = 0 ; (a - 16) = 0
-a = -30 ; a = 16
a = 30
To check:
a = 30
-(30)² + 46(30) - 480 = 0
-900 + 1380 - 480 = 0
480 - 480 = 0
0 = 0
a = 16
-(16)² + 46(16) - 480 = 0
-256 + 736 - 480 = 0
480 - 480 = 0
0 = 0
The first drop box answer is A. The second one is about 18,000
