<u>Answer: </u>
Makya was conducting a physics experiment. At 15th second, distance rolled will be 29 feet.
<u>Solution:
</u>
Given that Makya is conducting physics experiments.
He rolled a ball down a ramp and calculated the distance covered by the ball at different time.
Ball rolled a distance of 1 foot during first second.
Ball rolled a distance of 3 feet during second second.
Given that distance rolled with the time formed an arithmetic sequence.
We need to calculate distance rolled at 15th second that is 15th term of Arithmetic sequence when,
Hence at 15th second, distance rolled will be 29 feet.
Answer:
The steps have been shown in the solution below
Step-by-step explanation:
LHS=RHS Hence, proved.
Let's use some examples. So what can you make with 16? You can make 1 and 15, 2 and 14, etc.
How about trying 1 and 15 first?
1*15 = 15
What about 2 and 14, 3 and 13, and 4 and 12?
2*14 = 28
3*13 = 39
4*12 = 48.
Now we notice a pattern-- the numbers keep getting bigger, right? So the closer you get to the middle, the bigger the area will get. So if we divide 16 by 2, we get 8. Let's try 8 and 8.
8*8 = 64
That's larger than 48! Now let's try a couple more to make sure.
9*7 = 63
10*6 = 60
11*5 = 55
Next time, you'll know that with one of these problems, the biggest area would be the two numbers closest to each other you can get. Hope this helps! :)
