Answer:
With the rule: d(n) = d(n-1) x (-5), we have:
d(1) = 8
d(2) = d(1)x(-5) = 8x(-5) =-40
d(3) =d(2)x(-5) = -40x-5 =200
Other way:
d(n) = d(n-1) x (-5) => d(n) = d(1)x(-5)^(n-1)
d(3) = d(1)x5^(3-1) =8x5^2=8x25 =200
From information given, we know
208 miles was at rate of 65 mph. so divide total mileage by speed to get time spent.
208 ÷ 65 = 3.2 hours
So the rest of the trip took 6 - 3.2 = 2.8hours to travel another 348 total miles minus the 208 miles driven at 65mph is 140 miles.
140 miles divided by 2.8 hours gives speed
140 ÷ 2.8 = 50 miles per hour
The situation above described that Jeff added two - thirds of 128 to the flour. The numerical value of (2/3)(128) is 85.33 grams. The recipe says to add only 32 grams of vanilla powder. Hence, Jeff went over the prescribed amount.
To determine the excess amount, subtract 32 from 85.33 which has a numerical value of 53.33 grams.
