Answer:
Step-by-step explanation:
As given t-1 4/9+4 5/9=3 2/9
t-13/9+41/9=29/9
t=29/9-41/9+13/9
now taking L.C.M
t=(29+13-41)/9
t=(42-41)/9
t=1/9
Answer:
A) 32 kg/m
B) 48 kg/m
C) 72 kg/m
Step-by-step explanation:
We are given mass is; m = 4x²
Linear density is the derivative of mass with respect to the position x. So linear density is;
ρ = dm/dx
Differentiating 4x²,we have; ρ = 8x
A)at x = 4; ρ = 8(4) = 32 kg/m
B) at x = 6; ρ = 8(6) = 48 kg/m
C) at x = 9; ρ = 8(9) = 72 kg/m
A) after 5 years she will pay $7,200
b) she will save $2880
Step-by-step explanation:
