5.sometimes

6.always

Step-by-step explanation:

It is clear from the given number line, that $m$ is a negative integer and $n$ is a positive integer.

1. It is always true because addition is always commutative property.

2. It is never positive because product of two different sign is always negative.

3.dividing two integer with unlike sign may result in any integer

4.when a positive quantity is reduced from a negative quantity, the result is always negative.

5.division of two unlike integers may result the same,if they both have the same value

6.If an opposite of a positive integer is added to that positive integer itself, the result is is always 0.

A car bought for $13,000 depreciates at 15% per year. Use an exponential function to find the value of the car after 5 years.

earnstyle [38]

Answer:

$5768.1

Step-by-step explanation:

Given data

Cost price= $13,000

Depreciation= 15%

Time= 5 years

The expression for the depreciation is given below

A= P(1-r)^t

Substitute

A=13000(1-0.15)^5

A=13000(0.85)^5

A=13000*0.4437

A=$5768.1

Hence after 5 years, the car will be $5768.1

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.
