You never gave the speed of the blue train.
The path to collision is equal to 1½ circles.
1.5 x 210 meters
= 315 meters
I'm going to arbitrarily guess the speed of the blue train is 15 meters per minute. They are therefore approaching each other at a combined rate of 35 meters per minute.
315 / 35 = 9 minutes
Answer:
9 minutes
10/14 = 5/7 in simplest form
The next three terms of -243, 81, -27, 9 is The given series is geometric series
<u>Solution:</u>
Given, series is -243, 81, -27, 9, …
We have to find the next three terms of the above given series.
Now, the given series can also be written as
We can say that, above series is in Geometric Progression with first term = -243 and common ratio =
Then, next three term would be,
Hence, the next three terms of given G.P series are
Answer:
Step-by-step explanation:b
No real roots. Roots will have imaginary numbers. This means the quadratic is either always above the axis, or always below.
One real root. The graph touches the x
-axis in one place. →
Two real roots. The graph crosses the x
-axis twice.
I don't get how to do this problem
