Answer:
9765625
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
r = 25 ÷ 5 = 125 ÷ 25 = 5
This indicates the sequence is geometric with n th term
= a₁![r^{n-1}](https://tex.z-dn.net/?f=r%5E%7Bn-1%7D)
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = 5 , then
a₁₀ = 5 ×
= 5 × 1953125 = 9765625
Answer:
The first ship has the same speed as Saige's ship while the second and third do not have the same speed.
Step-by-step explanation:
d = Distance traveled by Saige's spaceship = 588 km
t = Time taken = 60 seconds
Speed is given by
![s=\dfrac{d}{t}\\\Rightarrow s=\dfrac{588}{60}\\\Rightarrow s=9.8\ \text{km/s}](https://tex.z-dn.net/?f=s%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5CRightarrow%20s%3D%5Cdfrac%7B588%7D%7B60%7D%5C%5C%5CRightarrow%20s%3D9.8%5C%20%5Ctext%7Bkm%2Fs%7D)
The other ships
![s=\dfrac{441}{45}=9.8\ \text{km/s}](https://tex.z-dn.net/?f=s%3D%5Cdfrac%7B441%7D%7B45%7D%3D9.8%5C%20%5Ctext%7Bkm%2Fs%7D)
![s=\dfrac{215}{25}=8.6\ \text{km/s}](https://tex.z-dn.net/?f=s%3D%5Cdfrac%7B215%7D%7B25%7D%3D8.6%5C%20%5Ctext%7Bkm%2Fs%7D)
![s=\dfrac{649}{110}=5.9\ \text{km/s}](https://tex.z-dn.net/?f=s%3D%5Cdfrac%7B649%7D%7B110%7D%3D5.9%5C%20%5Ctext%7Bkm%2Fs%7D)
So, the first ship has the same speed as Saige's ship while the second and third do not have the same speed.
Answer:
Jermey is not correct because abouslte value is always postive
Step-by-step explanation:
(27 mi/hr) x (1 hr / 60 min) = (27/60) (mi/min) = 0.45 mile/minute
Using the same kind of calculation, we can see
that the world record times for other distances
correspond to:
200 meters 23.31 mph
400 meters 20.72 mph
800 meters 17.73 mph
1000 meters 16.95 mph
1500 meters 16.29 mph
1 mile (1,609 meters) 16.13 mph
2,000 meters 15.71 mph
10,000 meters 14.18 mph
30,000 meters 12.89 mph
Marathon (42,195 meters) 13.10 mph
Except for that one figure at the end, for the marathon,
which I can't explain yet and I'll need to investigate further,
it's pretty obvious that a human being, whether running for
his life or for a gold medal, can't keep up the pace indefinitely.
