Answer:
t = 5 or t = 0
Step-by-step explanation:
Solve for t:
12 t (t - 5) = 0
Divide both sides by 12:
t (t - 5) = 0
Split into two equations:
t - 5 = 0 or t = 0
Add 5 to both sides:
Answer: t = 5 or t = 0

Answer:
160,000? i think
Step-by-step explanation:
Answer:
y^1 / x^4
Step-by-step explanation:
Formulas : -
p^q / p^r = p^( q - r )
p^q . p^r = p^( q + r )
p^-q = 1 / p^q
x^4 y^6 x^-2
------------------
y^3 y^2 x^8
= x^4 y^6 x^-2
------------------
y^3 y^2 x^8
= x^4 x^-2 y^6
------------------
y^3 y^2 x^8
= x^( 4 + ( - 2 ) ) y^6
-------------------------
y^( 3 + 2 ) x^8
= x^( 4 - 2 ) y^6
------------------
y^5 x^8
= x^2 y^6
------------------
x^8 y^5
= x^( 2 - 8 ) y^( 6 - 5 )
= x^-4 y^1
= y^1 / x^4
