1 answer:

Answer:

Max

Step-by-step explanation:

y" = -2

Basically is a constant value of -2, which doesn't depend on x.

Find the turning point using y' = 0.

y' = 4 - 2x = 0

4 - 2x = 0

x = 2

So the turning point is at x = 2,

y = 5 + 4(2) - 2² = 9

(2,9) is the turning point

For the nature (max/min):

y" = -2

Since y" < 0, it is a maximum turning point

A crew of highway workers paved 1/2 mile in 1/4 hour. If they work at the same rate, how much will they pave in one hour?
mote1985 [20]

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than

20

minutes. The longer the time, the more they will pave.

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by

20

) and them multiply by

60

to find how much in one hour.
