Suppose that 2 ≤ f '(x) ≤ 3 for all values of x. what are the minimum and maximum possible values of f(5) − f(1)?
zzz [600]

Assuming f is differentiable over the interval (1, 5), by the mean value theorem we know that there is some 1 such that

f'(c)=\dfrac{f(5)-f(1)}{5-1}

We're given that 2\le f'(x)\le3 for all x, so

2\le\dfrac{f(5)-f(1)}4\le3\implies8\le f(5)-f(1)\le12

that is, the minimum possible value is 8, and the maximum possible value is 12.

Challenge fr y'all. solve this to get 50 points and brainliest coming up if you get the right answer
TEA [102]

Answer:

  • See below

Step-by-step explanation:

a)

i)

<u>Use the law of cosines:</u>

  • AB=\sqrt{PA^2+PB^2-2*PA*PB*cosP}
  • AB=\sqrt{60^2+100^2-2*60*100*cos80} =\sqrt{11516.22} =107.31

ii)

<u>Use the law of sines:</u>

  • sin ∠A / PB = sin ∠P / AB
  • sin ∠A / 100 = sin 80 / 107.31
  • sin ∠A = 100 sin 80 deg / 107.31
  • sin ∠A = 0.92
  • ∠A = arcsin 0.92
  • ∠A = 67° (rounded)

iii)

<u>Bearing of B from A:</u>

  • 90° + (67° - 30°) =
  • 127°

b)

<u>PB is longer distance. Time to reach B:</u>

  • t = d/s
  • t = 100/20 = 5 hours

<u>The speed s of the slower ship:</u>

  • s = d/t
  • s = 60/5 = 12 km/h
