How long will it take for an investment to double in valve if it earns 12.25% compounded continuously ?

Mathematics

Answer:

At the given rate it will take 3 years and 5 months for the investment to be doubled

Step-by-step explanation:

Here, we want to get the amount of time it will take an investment that earns 12.25% to double if it’s compounded continuously

We can have the exponential relation as follows;

P = I( 1 + r)^n

P is the present value, let us call this 2x as it two times the initial

I is the initial value which is x in this case

r is the interest rate = 12.25% which is same as 12.25/100 = 0.1225

n is the number of years which we want to calculate

Thus, we have

2x = x( 1 + 0.1225)^n

2 = 1.225^n

Ln 2 = n ln 1.225

n = ln 2/ln 1.225

n = 3.42

if 3.42 is the number of years, let us have 0.42 in months

That will be 0.42 * 12 = 5.04

So we are looking at the investment being doubled at 3 years and 5 months

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27 pi feet cubed.
LenaWriter [7]

Answer:

C. V = two-thirds (27)

Step-by-step explanation:

Given

Solid Shapes: Cylinder and Sphere

Volume of Cylinder = 27π ft³

Required

Volume of the sphere.

From the question,

<u>We have that</u>

1.  The volume of the sphere is the same as the volume of the cylinder

2. The height of the sphere is the same as the height of the cylinder.

From (2) above;

This means that the height of the cylinder equals the diameter of the sphere.

Let h represent the height of the sphere and d represent the diameter of sphere.

Mathematical, d = h

Recall that radius, r = r = \frac{d}{2}

Substitute h for d in the above expression

r = \frac{h}{2}. ----- (take note of this)

Calculating the volume of a cylinder.

V = πr²h

Recall that  V = 27; This gives us

27 = πr²h

Divide both sides by h

\pi r^2 = \frac{27}{h}

-------------------

Calculating the volume of a sphere

V = \frac{4}{3}\pi r^3

Expand the above expression

V = \frac{4}{3}\pi r^2 * r

Substitute \pi r^2 = \frac{27}{h}

V = \frac{4}{3} * \frac{27}{h} * r

Recall that r = \frac{h}{2}

So,

V = \frac{4}{3} * \frac{27}{h} * \frac{h}{2}

V = \frac{4}{3} * \frac{27}{2}

V = \frac{2}{3} * 27

V = \frac{2}{3} (27)

V = two-third (27)
