</span><span>equalize the two equations
</span>100x=3100 + 9x + 0.1x2
0.1x2-91x+3100=0

x2=874
the domain is </span>(0 ≤ x ≤ 500)
the value from which there are profits is 35 <span>pairs of cleats

Revenue: R(x) = 100x --------100*35=$3500
Profit: P(x)= 3100 + 9x + 0.1x2 -------3100+9*35+0.1*(35)2=$3537.5
Profit > Revenue up to the amount of 35 pairs of cleats
72 Kilometers = 72000 meters
1 hour = 3600 seconds
So if 72000m = 3600 secs
To find 1 sec, divide through by 3600
20m = 1 sec
To find the distance travelled in 15 secs we multiply by 15
300m = 20 secs
12/40 =0.3
28 *0.3 = 8.4
it will cast a 8.4 foot long shadow
Answer:
77
Step-by-step explanation:
-1 + 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 77
Hope this helps :)
