Alex Ar [27]

Answer:

52 dollars and 47 cents, or 52.47

Step-by-step explanation:

First, multiply 12 and 5.50, then you should get 66.00. Then, take the 25% discount, and divide it by a hundred, you should get 0.25, now multiply 0.25 and 66.00. You should get 16.50, thats your discount, so subtract 16.50 from 66.00, you should get 49.50. Now for the sales tax, divide 6.0 by 100, you should get 0.06. Now multiply 0.06 and 49.50, you should get 2.97, thats your tax, add it to 49.50, and you get 52.47 so BOOM, thats your answer, your welcome

7. The height of a ball in meters is modeled
s344n2d4d5 [400]

Answer:

the ball is in the air for 8 seconds

Step-by-step explanation:

f(x) = y

when y = 0, the ball would've travelled through the air over the final time of flight.

0 = -5x^2 + 40x + 0

use quadratic equation to find the value of x

x = (-b ± √b^2 - 4 • a • c) / 2 • a

x = (-40 ± √40^2 - 4 • -5 • 0) / 2 • -5

x = (-40 ± √1600) / - 10

x = (-40 ± 40) / - 10

x = 0 or x = 8
