#1). The length of the whole circumference is (π · D) = 12π .

   120° is 1/3 of 360°, so arc-AB is 1/3 of the whole circumference.

#2). 60° is 1/6 of 360°.
   So arc-CD is 1/6 of the whole circumference (which is given).

#3). The circumference of the circle is (π·D) = 20π .

   70° is (70°/360°) of the whole circle, so arc-XY
   is (70/360) of the whole circumference.

#4). Sorry, I don't remember anything right now about
   angles between chords.
   I hope what I've given you so far is worth 5 points.

Lim<br> t—>0 1-cos(2t) / sin^2 (11t)

Nitella [24]

Answer:

2/121

Step-by-step explanation:

Hello,

Hôpital's rule will help here.

$\forall t \in \mathbb{R}^*\\\\f(t)=1-cos(2t)\text{ *** f is differentiable}\\f'(t)=2sin(2t)\\f''(t)=4cost(2t)\\f''(0)=4 \\ \\g(t)=sin^2(11t)\text{ *** g is differentiable}\\g'(t)=2sin(11t)\times 11 \times cos(11t)=2\times 11 sin(11t)cos(11t)\\\\g''(t)=2\times 11 (11cos^2(11t)-11sin^2(11t))\\g''(0)=2\times 11^2$

So the limit is 4/(2*121)=2/121

Thanks

A soda company has determined that it's profit during lunch on a given day

DENIUS [597]

Answer:

15 sodas will give a maximum profit of 83

Step-by-step explanation:

For quadratic ax^2 +bx +c, the maximum occurs at x = -b/(2a). Here, we have ...

a = -1/3, b = 10

x = -b/(2a) = -10/(2(-1/3)) = 15

The profit for sale of 15 sodas is ...

P(15) = (-1/3s +10)s +8 = (-1/3(15) +10)(15) +8 = 5(15) +8 = 83

The company would earn a maximum of 83 from sale of 15 sodas.
