Answer:

D. f(8) = 1961

Step-by-step explanation:

i know the answer it is i think

To predict f(x) when x equals 8 we simply substitute.  

So f(x) = 25x2 28x + 585  

f(8) = 25 (8)^2 - 28 (8) + 585

f(8) = 25 * 64 - 224 + 585

f(8) = 1600 - 224 + 585 = 1961

Hencse f(8) = 1961

Hloo friend^_^..___

Q= f(x) = 25x2 − 28x + 585

Solution

________

f(8) = 25*(8)^2 - 28*8 + 585

= 25*64 - 224 + 585

= 1600 - 224 + 585

= 2185-224

= 1961 Ans...

So the correct ans is f(8) = 1961...

I HOPE ITS HELP U MY FRIEND..^_^

A log raft is moving downstream at a speed of 3 km/h. To insure that there are no river jams a supervisor travels along the raft
skad [1K]

Answer:

2000 meters

Step-by-step explanation:

When the motorboat is moving downstream, its speed relative to the ground is 18 km/h, so its speed relative to the raft is 15 km/h.

When the motorboat is moving upstream, its speed relative to the ground is 12 km/h, so its speed relative to the raft is again 15 km/h.

Converted to m/min, the relative speed is:

15 km/h × (1000 m/km) × (1 h / 60 min) = 250 m/min

It takes the motorboat 16 minutes to travel to the front of the raft and back.  Since the speed is the same in both directions, the motorboat takes 8 minutes to travel the length of the raft.

So the length of the raft is 250×8 = 2000 meters.

You need to make 5 grilled cheese sandwiches. You have a grill that is large enough to toast 2 sandwiches at a time. The sandwic
n200080 [17]
Each sandwich is toasted for 2 minutes and it takes 3 seconds to flip it.
The first two sandwiches will be toasted in 2 minutes (toasting) and 6 seconds (flipping).
The two will then be switched which will take 10 seconds.
The next two will again take 2 minutes and 6 seconds.
The final sandwich will take 5 seconds to be placed.
The final sandwich will also take 2 minutes to toast and 3 seconds to flip.
Total time:
2 + 2 +2 = 6 minutes
6 + 10 + 6 + 3 = 25 seconds
Total time is 6 minutes and 25 seconds.
