Answer:
$4125.00
14.94 years
$379.50
Step-by-step explanation:
1. A = P(1 + r/n)^(nt)
4837.65 = P(1 + 0.032/4)^(4×5)
4837.65 = P(1.008)^(20)
P = 4125.00
2. A = P(1 + r/n)^(nt)
10250 = 5125(1 + 0.0475/1)^(1×t)
10250 = 5125(1.0475)^t
2 = 1.0475^t
ln 2 = t ln 1.0475
t = 14.94
3. Beth pays the first $100, bringing the cost to $1118. She then pays 25% of this, which is $279.50. So she pays a total of $379.50.
Will actually no because your divide so you will do six divided by 3 thats give you 2

Answer:
76.25°
Step-by-step explanation:
The solution to the differential equation is an exponential curve with a horizontal asymptote at Tm. It passes through (0, 145) and (30, 95), so the equation can be written as ...
T = 80 +65((95-65)/(145-65))^(t/30)
T = 80 +65(3/8)^(t/30)
That is, the temperature difference is reduced to 3/8 of its original value in 30 minutes.
Since the coffee in cup B cools twice as fast, it will cool to the same temperature (95°) in 15 minutes. In the next 15 minutes, the temperature difference will be reduced to (3/8)^2 of the original 80°, so will be 11.25°. That is, the temperature of cup B will be ...
11.25° +65° = 76.25°
after 30 minutes.
