john invested $2000 that earn interest at 4% per annum compounded monthly. two year later the interest rate is 4.50% compounded

Ksju [112]

Answer:

$\$2,369.11$

Step-by-step explanation:

we know that

The compound interest formula is equal to

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

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

Part 1)

$t=2\ years\\ P=\$2,000\\ r=0.04\\n=12$

substitute in the formula above

$A=2,000(1+\frac{0.04}{12})^{12*2}$

$A=2,000(1.0033)^{24}$

$A=\$2,166.29$

Part 2)

$t=2\ years\\ P=\$2,166.29\\ r=0.045\\n=4$

substitute in the formula above

$A=2,166.29(1+\frac{0.045}{4})^{4*2}$

$A=2,166.29(1.01125)^{8}$

$A=\$2,369.11$

What is SV? Put the answer down below.

viktelen [127]

The measure of length SV is 60 units

<h3>Isosceles Right Triangle</h3>

An Isosceles right triangle is a right triangle that has equal opposite and adjacent sides.

The above means that:

$SV = ST$

Substitute values for SV and ST

$2z = z + 30$

Subtract z from both sides

$z = 30$

From the figure, we have:

$SV = 2z$

Substitute 30 for z

$SV = 2 \times 30$

$SV = 60$

Hence, the measure of length SV is 60 units
