Answer:

<h2>- 4 ⁷/₃₀</h2><h2 />

Step-by-step explanation:

<h2 />

= -3 2/5 - 5/6

= - 17/5 - 5/6  ---- LCM of 5 & 6 is 30

= _  <u>17 * 6</u>   _  <u> 5 * 5 </u>  

       5 * 6        6 * 5

=  _  <u>102 - 25 </u>

            30

=  _ <u> 127 </u>

        30

Answer:

  • - 4 7/30

Step-by-step explanation:

  • -3 2/5 - 5/6 =
  • - 17/5 - 5/6 =                        ⇒ converting the mixed fraction to standard
  • - 17*6/5*6 - 5*5/6*5 =          ⇒ bringing fractions to common denominator
  • - 102/30 - 25/30 =
  • - (102 + 25)/30 =
  • - 127/30 =                             ⇒ answer as standard fraction
  • - 4 7/30                                ⇒ converting to mixed fraction

How much interest does Ms. Paris earn on an $1800 loan for 6 months with a simple interest rate of 8.5%?
ddd [48]

Answer:

$1136.60

Step-by-step explanation:

The formula for exponential growth is f(x) = a(1 + r)^x where a is the initial value, r is the growth rate, and x is the number of time intervals.

We know that Mr. Paris starts with an $1800 initial value, so we can substitute that into the equation:

f(x)=1800(1 + r)^x

We also know the time intervals is 6 months. So that can be substituted as well:

f(x)=1800(1 + r)^6

They told you that the growth rate is 8.5%, which is 0.085 of 1.

f(x)=1800(1 + 0.085)^6

Add the 2 values in the parentheses and you get 1.085

f(x)=1800(1.085)^6

Now solve.

Order of operations requires you to raise 1.085 to the 6th power before multiplying by 1800. So then you have this:

1800(1.63146751) = 2936.64152. That rounds to 2936.60

So $2936.60 is the total amount of money in the bank account, but were looking for the interest earned, which is the difference between the end value and the initial value.

$2936.60 - $1800 = $1136.60

Domain and range of the inequality y&lt;√x+3 +1
Margaret [11]

The domain of the given inequality is y>1.

<h3>What is Inequality?</h3>

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Here, given inequality:

              y < \sqrt{x+3}+1

Related equation:

             y = \sqrt{x+3}+1

The equation defined as,

    x+3 > 0

    x > -3

In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.

So, the domain of the given inequality is x>-3.

We know that,

    \sqrt{x+3} \geq 0

adding 1 on both sides, we get

  \sqrt{x+3} + 1 \geq  1

      y ≥ 1

The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.

Thus, the domain of the given inequality is y>1.
