Answer: t^2 = 36 or 1
Step-by-step explanation: Divide everything by -5, and get t^2 -6t -5=0, Factoring is (t-6)(t+1), so t=6 or t=-1. Both squared are 36 and 1 so either of these could be the answer. Hope this helps!
Step-by-step explanation:
first we want to convert it to minutes so we multiply 60m/s by 60. 3600m/min or 3.6km/min
we just multiply 50 by 3.6.
therefore the car travels 180km south west
We can see that the only change that occurs to the points after the reflection is that the x-values are negated, because -4 becomes 4 and -6 becomes 6. And the only reflection that causes only a negation in the x-values is a reflection over the x-axis.

Answer:
12.5r + 200 = 12.5*2r
Step-by-step explanation:
<h3>Given</h3>
Rate of Hoppertunity = r
Rate of Dortmund = 2r as it is twice as fast
<h3>Solution</h3>
Let the distance Hoppertunity runs be d, then the distance Dortmund runs is d + 200 m
Since it took 12.5 seconds Dortmund to catch Hoppertunity, it can be expressed as:
- d = 12.5r for Hoppertunity
- d + 200 =12.5*2r for Dortmund
<u>By replacing d in the second equation, we get:</u>
<u>Soving</u>:
- 12.5r = 200
- r = 200/12.5
- r = 16 m/sec
Hoppertunity's rate is 16 m/sec
Dortmund's rate is 32 m/sec
