Answer:
Step-by-step explanation:
You need to subtract the coefficients to get the answer.
Let's look at the equation...
The coefficient is 3 and 1
So, you do 3-1
You get 2
So...
Show that n is odd →∃m∈ℤ,n2=8m+1
Let k be an integer so that n=2k+1. Then n2=(2k+1)2=4k2+4k+1=2(2k2+2k)+1.
But this isn't equal to 8m+1, so can I change that into 4(2m)+1?
The ratio is 10:8 at the moment, so you can simplify it down to 5:4.
Answer:
strange phrasing of a question
If one assumes that the "observation" was from 3:00 pm - 5:00 pm (2 hours)
and the ball was ONLY "bounced" 10 times (3+7)
we can can say that the rate was 10 bounces/2 hours or 5 b.p.h. (bounces per hour)
