Answer:

s = 2

Step-by-step explanation:

The length of the arc s is calculated using

s = circumference × fraction of circle

  = 2πr × \frac{0.4}{2\pi } ( cancel 2π )

  = 5 × 0.4 = 2

Answer:

Length of arc S = 2 units

Step-by-step explanation:

Circumference of the circle = 2πr

Here r = radius of the circle

Now length of the intercepted arc by the sector will be

S = Length of Circumference × \frac{\text{angle inscribed by the sector}}{2\pi}

S = 2\pi r\times {\frac{0.4}{2\pi } }  [Angle inscribed by the sector is 0.4 radians]

  = 0.4r

  = 5 × 0.4

  = 2.0 units

Therefore, length of arc S is 2 units.

Stuck on question 1, can anyone help???
poizon [28]

'A' is the square root of 25. That's 5, so take A=5 with you
as you go to the next step.

B is A³.   A³ means (A x A x A).  We know that 'A' is 5, so 'B' is (5x 5 x 5) = 125 .
Take B=125 with you to the next step.

'C' is  B - 25.  We know that  'B'  is 125.  So  C = (125 - 25) = 100 .
Take  C=100  with you to the next step.

'D' is the square root of  'C'.  We know that C=100, so  D = √100 .
The square root of 100 is 10, so  D=10.
Take  D=10  with you to the next step .

'E' is  D+39.  We know that  D=10.  So  E=(10+39) = 49 .
Take  E=49 with you to the last step.

'F' is the square root of 'E'.  We know that E=49.

Find the maximum and minimum values of f(x,y) = 8x+y for the polygonal convex set having vertices at (0, 0), (4, 0), (3, 5), (0,
Helen [10]
F(x,y)=8x+y

This means, f is a function where we plug in pairs of numbers.
then, f calculates the first number times 8, to which it then adds the second number we plugged.

let's calculate f for the vertices:

f(0,0)=8*0+0=0+0=0

f(4, 0)=8*4+0=32+0=32

f(3, 5)=8*3+5=24+5=29

f(0, 5)=8*0+5=0+5=5

the maximum value of f is 32
the minimum value of f is 0
