9.7 × 10³
Answer:
The answer is (2u-1)(5u+1)=0
Step-by-step explanation:
Answer:
k ≈ - 0.069
Step-by-step explanation:
Given
A = 800
Substitute A = 400 and t = 10 into the equation
400 = 800 ( divide both sides by 800 )
0.5 = ( take the ln of both sides )
ln = ln0.5
10k lne = ln0.5 [ lne = 1 ]
10k = ln 0.5 ( divide both sides by 10 )
k = ≈ 0.069 ( to the nearest thousandth )
The lateral surface area is 148. This is because you need to use the formula 2(LW+WH+LH)
