Answer: The farmers have to plough 1680 acres of land.

Step-by-step explanation:

Let the expected time to complete the plowing be 'x'.

In x days, a group of farmers had to plough = 112 acres

According to question, on exceeding the schedule by 8 acres per day, the farmers finished plowing one day earlier than expected.

So, New time = x-1

Number of acres of land becomes

112+8=120\ acres

So, According to question, it becomes,

112\times x=120\times (x-1)\\\\112x=120x-120\\\\120=120x-112x\\\\120=8x\\\\x=\frac{120}{8}=15

So, Total acres of land the farmers have to plough is given by

15\times 112=1680\ acres

Hence, the farmers have to plough 1680 acres of land.

112+8 each day

112:8=14 so for each 14 days they had 8 acres extra until they finish early 1 day so they did not had to work the 15th day.

Since 15 days were scheduled with 112 each day they plough 112•15=1,680 acres

Find the absolute minimum and absolute maximum values of f on the given interval. f(x) = x − ln 8x, [1/2, 2]
insens350 [35]
The given function is 
f(x) =  x - ln(8x), on the interval [1/2, 2].

The derivative of f is
f'(x) = 1 - 1/x
The second derivative is 
f''(x) = 1/x²

A local maximum or minimum occurs when f'(x) = 0.
That is,
1 - 1/x = 0  => 1/x = 1  => x =1.
When x = 1, f'' = 1 (positive).
Therefore f(x) is minimum when x=1.
The minimum value is
f(1) = 1 - ln(8) = -1.079

The maximum value of f occurs either at x = 1/2 or at x = 2.
f(1/2) = 1/2 - ln(4) = -0.886
f(2)  = 2 - ln(16) = -0.773
The maximum value of f is
f(2) = 2 - ln(16) = -0.773
A graph of f(x) confirms the results.

Answer: 
Minimum value  = 1 - ln(8)
Maximum value = 2 - ln(16)

If B is in the interior of ∠DEF, m∠DEB = 27.2, and m∠DEF = 92.5, find m∠BEF. (Lesson 2-7)
Westkost [7]

Answer:

m∠BEF = 65.3°

Step-by-step explanation:

Given:

m∠DEB = 27.2,

m∠DEF = 92.5

Required:

m∠BEF

SOLUTION:

Since B is the interior of ∠DEF, it means ∠DEB and ∠BEF are adjacent angles that make up ∠DEF. And they share the same side, BE.

Therefore:

m∠BEF + m∠DEB = m∠DEF (angle addition postulate)

m∠BEF + 27.2 = 92.5

Subtract 27.2 from each side

m∠BEF + 27.2 - 27.2 = 92.5 - 27.2

m∠BEF = 92.5 - 27.2

m∠BEF = 65.3°
