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.

Find the measure for LQR.

Charra [1.4K]

Answer:

Option A

$m\angle LQR=126^o$

Step-by-step explanation:

step 1

Find the value of b

we know that

$m\angle MQR=m\angle LQX$ ----> by vertical angles

substitute the given values

$(-3b+63)^o=(90-12b)^o$

solve for b

$12b-3b=90-63\\9b=27\\b=3$

step 2

Find the measure of angle LQR

we know that

$m\angle LQR+m\angle MQR=180^o$ ---> by supplementary angles (form a linear pair)

$m\angle MQR=(-3b+63)^o$

substitute the value of b

$m\angle MQR=(-3(3)+63)=54^o$

substitute in the expression above

$m\angle LQR+54^o=180^o$

$m\angle LQR=180^o-54^o=126^o$

X + 14= -6 idk what the answer is please help me right away

stiv31 [10]

Answer:

x = -20

Step-by-step explanation:

You move the 14 with the 6, since it is addition, it changes symbols ( from + to - ), so it'd be;

x = -6 - 14, since you are subtracting a negative number, you are technically adding them.
