the sum of polynomials is $3x^{2}$ + 6x + 4

Step-by-step explanation:

Question:

(6x+7+ $x^{2}$ ) + ( $2x^{2}$ - 3)

Step 1: Open the bracket according to BODMAS rule

6x+7+ $x^{2}$ + $2x^{2}$ - 3

Step 2: Arrange

x^{2}[/tex] + $2x^{2}$ + 6x + 7 - 3

Step 3: Simplify

$3x^{2}$ + 6x + 4

Therefore, the sum of polynomials is $3x^{2}$ + 6x + 4

Find the face value of the 20-year zero-coupon bond at 4.4%, compounded semiannually, with a price of $8,375.

umka21 [38]

Given:

Time,

t = 20 years

Rate,

r = 4.4%

Price

= $8,375

Now,

The yield will be:

= $\frac{4.4}{2}$

= $1.1$ (%)

Time will be:

= $20\times 2$

= $40 \ periods$

As we know the formula,

⇒ $Price \ of \ bond = \frac{Face \ value}{(1+\frac{r}{2} )^{n\times 2}}$

By substituting the values, we get

$8375=\frac{Face \ value}{(1+\frac{0.044}{2} )^{20\times 2}}$

$8375=\frac{Face \ value}{(1.022)^{40}}$

$8375=\frac{Face \ value}{2.3880083}$

The face value will be:

$Face \ value = 2.3880083\times 8375$

$=20,000$ ($)

SAVINGS ACCOUNT

yarga [219]

Answer:

$4000 was invested at 4%, 2500 was invested at 3%

Step-by-step explanation:

First and foremost the question has to be define.

Total amount raised is $6500

Savings account percentage simple interest =3%

Government Bond: 4% simple interest

Equation for amount invested at each rate:

(6500-x)0.03 + 0.04x = 235

195 - 0.03x + 0.04x = 235

0.01x = 40

x = 4000

$4000 was invested at 4%, 2500 was invested at 3%
