abruzzese [7]3 years ago

Answer:

.3-.6 ; 0-.6 ; .1-.3 ; 0-.3 ; 0-.1

Step-by-step explanation:

The "points" are:

(0,96.44), (.1,97.6), (.3, 98.57), and (.6, 98.3)

The "rate of change" is the slope. This means that the change from...

0-.1 is (97.6-96.44)/.1 = 1.16/.1= 11.6

0-.3 is (98.57-96.44)/.3 = 2.13/.3 = 7.1

0-.6 is (98.3-96.44)/.6 = 1.86/.6 = 3.1

.1-.3 is (98.57-97.6)/.2 = .97/.2 = 4.85

.3-.6 is (98.3-98.57)/.3 = -.27/.3 = -.9

m = 5 and n = 3

let f(x) = 2x³ - mx² + nx - 2 , then

f( - 1 ) = - 2 - m - n - 2 = - 12

f(2 ) = 16 - 4m + 2n - 2 = 0

Tidying up the 2 equations

- m - n = - 8 → (1)

- 4m + 2n = - 14 → ( 2)

multiply equation ( 1) by 2

- 2m - 2n = - 16 → ( 3 )

add ( 2 ) and ( 3 ) term by term

-6m = - 30 ⇒ m = 5 ( substitute m = 5 into (2 )

- 20 + 2n = - 14

2n = 6 ⇒ n = 3

just olya [345]
To find the sale price multiply the original cost by the sale percentage. (37x.2= 7.4) subtract this discount from the total (37-7.4= 29.6) this is your sale price. Now multiply this by the other percentage (29.6x.15= 4.44) (29.6-4.44= 25.16) $25.16 is your final answer
