5 feet 5 inches is the same as 65 inches, so LAMAR is taller.
Divide 74 into 4 and 6
74/4 = 18,5
74/6=12,33
so if you buy in bags of 4 you need 19 bags, which costs 5 x 19 = $95
if you buy in bags of 6 you need 13 bags, which costs 7 x 13 = $91
Buying in bags of 6 costs less.
Answer:
Step-by-step explanation:
1.3 x 10^-5
0.000013
answer is B
Recall that
d/dx sech(x) = - sech(x) tanh(x)
d/dx tan⁻¹(x) = 1/(1 + x²)
Then by the chain rule,
dy/dx = - sech(x) tanh(x) / (1 + x²)
