3 different ways to write 5^11

Mathematics
1 answer:
SVEN [57.7K]2 years ago
5 0

Answer:

There are many ways we can write 5^{11} one of them being that we just write 11 fives being multiplied against each other like the following:

5*5*5*5*5*5*5*5*5*5*5

This can seem very repetitive which is why powers are a lot more helpful.  We can also rewrite 5^{11} using the power in the bottom of a fraction.  The way that we do this is put 5^{-11} on the bottom which can then be flipped to the top with a positive power and will be the same.

\frac{1}{5^{-11}}

The final way that we can rewrite 5^{11} is by using several different powers.  We can do 5^6*5^5 which will equal the same thing as 5^{11} because the base is the same and what we basically do is just add up the powers together to get back to 11.

5^6*5^5

Two airplanes leave an airport at the same time, flying in the same direction. One plane is flying at twice the speed of the oth
olasank [31]

Answer:

One plane has a speed of 450 km/h and the other has a speed of 900 km/h.

Step-by-step explanation:

I am going to say that:

The speed of the first plane is x.

The speed of the second plane is y.

One plane is flying at twice the speed of the other.

I will say that y = 2x. We could also say that x = 2y.

Two airplanes leave an airport at the same time, flying in the same direction

They fly in the same direction, so their relative speed(difference) at the end of each hour is y - x = 2x - x = x.

If after 4 hours they are 1800 km apart, find the speed of each plane

After 1 hour, they will be x km apart. After 4, 1800. So

1 hour - x km apart

4 hours - 1800 km apart

4x = 1800

x = 1800/4

x = 450

2x = 2*450 = 900

One plane has a speed of 450 km/h and the other has a speed of 900 km/h.

3. Given: Circle Q<br>&lt;A = 35<br>Find: m AB​
Agata [3.3K]

Answer:  110°

<u>Step-by-step explanation:</u>

∠A ≅ ∠B  

since ∠A = 35° (given), then ∠B = 35°

Use the Triangle Sum Theorem to find ∠C:

∠A + ∠B + ∠Q = 180°

35° + 35° + ∠Q = 180°

     70°    + ∠Q = 180°

                 ∠Q = 110°

The central angle (∠AQB) ≅ arc AB

since ∠AQB = 110° (solved above), then arc AB = 110°
