Answer:
c. 19,712
Step-by-step explanation:
2,816 * 7 = 19,712
Δ = b^2 - 4.a.c = 4 - 4.6.3 = -68< 0
rootΔ = root(-68)
no real solutions :) Cause -68 not positive.
Good Luck :)
Answer:
4√6^3
Step-by-step explanation:
I=k/d^2
4=k/d^2 and 1=k/64 so if we divide the first by the second we get:
4/1=(k/d^2)/(k/64)
4=(k/d^2)*(64/k)
4=64/d^2
d^2=64/4
d^2=16
d=4 meters
