Compute the total and annual returns on the following investment. Twenty years after purchasing shares in a mutual fund for $63

lesya [120]

Answer:

76.2% total return
2.87% annual return

Step-by-step explanation:

The total return is the rate of increase over the whole period:

% change = (11100/6300 -1) × 100% = 76.2%

The annual return is the rate of return that gives this growth over 20 years:

(1 +r)^20 = 1 +76.2%

r = 1.762^(1/20) -1 ≈ 2.87%

The total return is about 76.2%; the annual return is about 2.87%.

Solve the inequality 4x-7<5

Elza [17]

4x - 7 < 5

Add 7 to the both sides,
4x - 7 + 7 < 5 + 7
4x < 12

Divide 4 from the both sides,
4x/4 < 12/4
x < 3

So, your final answer is x < 3

Hope this helps!

The mass, m grams, of a radioactive substance, present at time t days after first being observed, is given by the formula m=24e^

Reika [66]

Answer:

(i) The value of m when t = 30 is 13.2

(ii) The value of t when the mass is half of its value at t=0 is 34.7

(iii) The rate of the mass when t=50 is -0.18

Step-by-step explanation:

(i) The m value when t = 30 is:

$m = 24e^{-0.02t} = 24e^{-0.02*30} = 13.2$

Then, the value of m when t = 30 is 13.2

(ii) The value of the mass when t=0 is:

$m_{0} = 24e^{-0.02t} = 24e^{-0.02*0} = 24$

Now, the value of t is:

$ln(\frac{m_{0}/2}{24}) = -0.02t$

$t = -\frac{ln(\frac{24}{2*24})}{0.02} = 34.7$

Hence, the value of t when the mass is half of its value at t=0 is 34.7

(iii) Finally, the rate at which the mass is decreasing when t=50 is:

$\frac{dm}{dt} = \frac{d}{dt}(24e^{-0.02t}) = 24(e^{-0.02t})*(-0.02) = -0.48* (e^{-0.02*50}) = -0.18$

Therefore, the rate of the mass when t=50 is -0.18.

I hope it helps you!
