Answer: Assuming by similar it means proportional, I'd suppose D.
Answer:
D because 6/30 is not the same as 2:10
Answer:
y = -1/4 (x + 2)² + 4
Step-by-step explanation:
y = -1/4x² - x + 3
y = - 1/4 ( x² + 4x - 12)
y = -1/4 (x² + 4x + 4) + 3 + 1
Y = -1/4 (x + 2)² + 4
For the answer to the question above, we'll have to use the formula for velocity which is v =<u> d
</u> t and d = vt
Since the total distance is given, therefore we can get the time and it will look like this.
220t + 250t = 1880
<u>470t</u> = <u>1880
</u>470 470
the problem indicates that the train runs 250kph
Let's substitute:
d = 250(4)
the distance traveled by Lian is 1000km
<u>
</u>
