A circle has a circumference of 6. It has an arc of length

Minchanka [31]

Answer:

Ф = CO/(6 units)

Step-by-step explanation:

The formula for arc length is s = rФ, where Ф is the central angle. This can be solved for Ф, the central angle:

arc length

Ф = ------------------

radius

If the given arc length is represented by CO, then the central angle is

Ф = CO/(6 units)

If f(n) = -6n + 2, find f (5/6)

joja [24]

$f( \frac{5}{6} ) = - 6( \frac{5}{6} ) + 2 \\ f( \frac{5}{6} ) = - \frac{30}{6} + 2 \\ f( \frac{5}{6} ) = - 5 + 2 \\ f( \frac{5}{6} ) = - 3$

The number of phone calls between two cities, N, during a given time period varies directly as the populations p 1 and p 2 of t

kherson [118]

Answer:

∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.

Step-by-step explanation:

Given that,

The number of phone calls between two cities (N )

directly proportional as the value of populations $p_1$ and $p_2$ of two cities.
Inversely varies as the magnitude of distance (d).

$N\propto\frac{p_1p_2}{d}$

$N=k.\frac{p_1p_2}{d}$

Given that,

N=18,000, d=310 miles, $p_1$ =15,500 and $p_2$ =180,000

$18,000=k.\frac{15,500\times 180,000}{310}$

$\Rightarrow k=\frac{18,000\times310}{15,500\times 180,000}$

$\Rightarrow k=\frac{31}{15,500}$

Now,

N=? , d=435 miles, $p_1$ =100,500 and $p_2$ =160,000

$N=\frac{31}{15,500}.\frac{100,000\times 160,000}{435}$

$\Rightarrow N\approx 73,563$

∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
