No, unless you live to be freakishly old. the light would take 120 years to reach your eyes, and even then, you would be seeing what happened 120 years ago.

An aircraft is climbing at a 30 degree angle to the horizontal. How fast is the aircraft gaining altitude if it's speed is 500 m
denis-greek [22]

Answer:

The aircraft is gaining altitude at 250\frac{mi}{h}

Explanation:

Draw a vector diagram. (Right angle triangle speed as the hypotenuse)

Let

x -----> horizontal component of the speed

y ----> vertical component of the speed

s ----> speed in miles per hour

we know that

x=cos(30\°)(s)

y=sin(30\°)(s)

we have

s=500\ \frac{mi}{h}

cos(30\°)=\frac{\sqrt{3}}{2}

sin(30\°)=\frac{1}{2}

substitute

x=\frac{\sqrt{3}}{2}(500)

x=250\sqrt{3}\frac{mi}{h}

y=\frac{1}{2}(500)

y=250\frac{mi}{h}

therefore

The aircraft is gaining altitude at 250\frac{mi}{h}

To order tickets online to a hockey game, there is a processing fee plus the cost per ticket. The cost for 5 tickets is $174.45.
romanna [79]

Answer:

(34.89 x 6) + (33.99 x 6) = 413.28

Step-by-step explanation:

1. Find the unit rate of each ticket if the deal is 5 tickets. 174.45 ÷ 5 = 34.89

2. Find the unit rate of each ticket if the deal is 8 tickets. 271.95 ÷ 8 = 33.99

3. Now that we know our unit rates for the different deals, generate your    equation.

Population patterns shown on the map indicate that areas around river deltas and upland lake and river valleys have higher densi
butalik [34]

The statement that explains why these regions are more heavily populated is because E. these regions have higher carrying capacities.

  • Carrying capacity refers to the average population density of an area.  It should be noted that the average population size of a particular organism can be due to several environmental factors.

  • It should be noted that the areas around river deltas, upland lakes, and river valleys will have higher densities.

  • The reason for this is because people will love to live around such areas and they, therefore, have higher carrying capacities.

In conclusion, the correct option is that the regions have higher carrying capacities.
