The THIRD statement is not true.
$2000 (spends a month)
The 5% of $2000 is only $100 for food.
The first statement is true "The household spend $260 per month on the car".
13 % of $2000 = $260
The second statement is true "The household spend $600 per month for rent".
30% of $2000 = $600
The fourth statement is also true "The household spend $200 in savings each month"
10% of $2000 = $200
F(t) = (t^-1) - t
Taking derivative:
<span>f'(t) = d/dt(t^-1) - t) = d/dt(t^-1) - d/dt(t) </span>
<span>f'(t) = -1(t^-2) -1
= -t^-2 - 1 </span>
<span>f'(t) = v(t),
It can be also written as :
-1/t^2 - 1 </span>
<span>So v(3) = -1/(3^2) - 1 = -1/9 - 1 = -10/9</span>
f(x) = 2 + 3cos(10π(x - 3))
f(47) = 2 + 3cos(10(3.14)(47 - 3))
f(47) = 2 + 3cos(31.4(45))
f(47) = 2 + 3cos(1413)
f(47) = 2 + 3(0.891006524)
f(47) = 2 + 2.673019573
f(47) = 4.673019573
