Answer:
Step-by-step explanation:
first runs n+1 laps
and second runs n laps in the same time.
so (n+1)8=10n
10n=8n+8
10n-8n=8
2n=8
n=8/2=4
one lap=1 mile
4 laps=4 miles
4+1=5 laps=5 miles.
first runs 5 miles whereas second runs=4 miles.
Answer:
We have to use the formule to calculate the vertex which is: V(-b/2a;4ac-b^2/4a)
A) y=x+7 where a=1 b=0 and c=7
By replacing we have: V(0;28/4) V(0;7)
B) y=-x where a=-1 b and c=0 so V(0,0)
Here for 120, the expression for the start root and end root is given
<h3>What will be the expression for start root and enroot of 120?</h3>
Here we need to find 
By simplifying the given expression, we get:
by taking square roots on both sides we get
Thus for 120, the expression for the start root and end root is given
