posledela

Answer:

6 hour 20 minutes

Step-by-step explanation:

We are given that a space plane skims  the edge of space at 400 miles per hour.

Circumference of the planet=25000 miles approximately

We have to find the time taken by the plane to travel around the planet.

Speed of plane=4000 miles per hour

Total distance traveled by the plane= approximately 25000 miles

Because plane travel in circular path therefore, distance

traveled by plane=Circumference of planet

Time =\frac{distance}{speed}

Substitute the values then we get

Time =\frac{25000}{4000}=\frac{25}{4}=6\frac{1}{4} hours

Time=6 hour +\frac{1}{4}\times 60 minutes= 6\;hour\;20 minutes

1 hour=60 minutes

Hence, the plane takes time to travel around the planet=6 hour 20 minutes

I need help figuring out the steps to solving these kind of problems
pantera1 [17]
First off, get the equation to be x-3y=6. Then plug in numbers! If x=6, then y=0. In addition, if x=0, y=-2. Draw a line. After that, you can plug in some numbers after drawing the line to see if you should shade on top of the line or on the bottom

Answer:

Step-by-step explanation:

4. f(x) = √(x + 4)

f(5) = √(5+4) = √(9) = 3

5. g(x) = x^12 - x^5

  g(-1)=          (-1)^12 - (-1)^5

             1 - (-1) = 1 + 1 = 2
