Answer:

2419.0265 meters

Step-by-step explanation:

To find the answer you must first find the circumference of the circle. The circumference formula is C = 2 \pi r. So if you plug in 77 you get 483.8053. Then multiply that by 5 and you will have your final answer.

An airplane takes off from the ground and reaches a height of 500 feet after flying 2 miles. given the formula h = d tan θ, wher
zloy xaker [14]

Height covered by the plane=h= 500 feet

Distance covered by the plane along the ground=d= 2 mile

Now, convert the mile into feet,

1 mile = 5280 feet

2 mile = 10560 feet

Now, use the formula

h= d tanθ

tanθ= h/d

tanθ= 500/10560

tanθ= 25/528

Take the tan⁻¹ on both side,

θ= tan⁻¹(25/528)

θ =2.71°

Answer:

Unidades a vender= 388

Step-by-step explanation:

Dada la siguiente información:

Costo variable unitario= $120

Costo fijo= $15,000

Precio de venta= $200

Utilidad deseada= $16,000 (supongo)

<u>Para calcular el número de unidades a vender, tenemos que usar está formula:</u>

<u></u>

Unidades a vender= (costo fijo +utilidad deseada) / contribucíon marginal

Unidades a vender= (15,000 + 16,000) / (200 - 120)

Unidades a vender= 388
