You have decided to invest $1000 in a savings bond that pays 4% interest, compounded semi-annually. What will the bond be worth

Evgen [1.6K]

Answer:

$2191.12

Step-by-step explanation:

We are asked to find the value of a bond after 10 years, if you invest $1000 in a savings bond that pays 4% interest, compounded semi-annually.

$FV=C_0\times (1+r)^n$ , where,

$C_0=\text{Initial amount}$ ,

r = Rate of return in decimal form.

n = Number of periods.

Since interest is compounded semi-annually, so 'n' will be 2 times 10 that is 20.

$4\%=\frac{4}{100}=0.04$

$FV=\$1,000\times (1+0.04)^{20}$

$FV=\$1,000\times (1.04)^{20}$

$FV=\$1,000\times 2.1911231430334194$

$FV=\$2191.1231430334194$

$FV\approx \$2191.12$

Therefore, the bond would be $2191.12 worth in 10 years.

Answer:

yes , 33^2 + 56^2 = 65^2 and obtuse

Step-by-step explanation:

<h2><u>Question 3</u></h2>

make use of the Pythagoras theorem

which is :

c^2 = a^2 + b^2

where c is the hypotenuse.

now put the values in the equation

65^2 = 56^2 + 33 ^2

the answer is :

<u></u>

<h2><u>Question 4</u></h2>

<u />

note if :

c^2 = a^2 + b^2 ----------- right

c^2 < a^2 + b^2------------ acute

c^2 > a^2 + b^2------------- obtuse

hence :

16 + 30 > 38

therefore its : <u>obtuse </u>
