Answer:

D. About 24 years

Step-by-step explanation:

Compounding is the means the future value of an amount saved today while discounting means the present value of a future amount.

In other words, we discount to know the present value of $1 in the future while we compound to know the future worth of $1 saved today.

Let the value of the investment be x. if it is expected to double in n years then using the compound interest formula

fv = pv(1 + r)^n

where fv and pv are the future and present values respectively and n is the time, r is the growth rate

2x = x(1 + 0.03)^n

2 = (1.03)^n

log 2 = log (1.03)^n

= n log 1.03

n = log 2/ log 1.03

n = 23.44

This is approximately 24 years hence option D is right

3 times 24 is 48% therefore its D.

1,030 at 4% compounded semiannually for 2 years

kotegsom [21]

Answer: $1114.91

Step-by-step explanation:

The formula for compound interest is

$A= P(1+\frac{r}{n})^{nt} \\$

Where

A = final amount

P = initial principal balance (1030 for this)

r = interest rate (0.04 for this)

n = number of times interest applied per time period (2 for this)

t = number of time periods elapsed (2 for this)

$A= 1030(1+\frac{.04}{2})^{(2)(2)} \\\\A= 1030(1+0.02)^{4} \\A=1030(1.02)^4\\A=1114.905125$

This rounds up to $1114.91

When we slice a three-dimensional object, we expose new faces that are two dimensional. The two-dimensional face is called _____

zlopas [31]

Answer:

Cross section

Step-by-step explanation:

Cross section refers to the new two dimensional face exposed when we slice through a three dimensional objects.

It can also be the surface or shape exposed by making a straight cut through something, especially at right angles to an axis.

Cross section is the plane surface(two-dimensional objects) formed by cutting across a solid shape (three-dimensional shape) especially perpendicular to its longest axis.
