$15-8i$

Step-by-step explanation:

we know that

The algebraic expression is equal to

$5\sqrt{9}-\sqrt{-64}}$

Remember that

$\sqrt{9}=3$

and

$i=\sqrt{-1}$

$\sqrt{-64}=i\sqrt{64}=8i$

substitute

$5\sqrt{9}-\sqrt{-64}}=5(3)-(8i)=15-8i$

A small business earns a profit of $6500 in January and $17,500 in May. What is the rate of change in profit for this time perio

MAXImum [283]

Rate of change of profit for this period is $2750 per month

Solution:

Given that,

Profit of $6500 in January and $17,500 in May

To find: Rate of change

Since,

January is the first month of the year (1) while May is the fifth month (5)

Therefore, we get two points

(1, 6500) and (5, 17500)

Using these points we can find the rate of change in profit for this time period

The rate of change using the following formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Here from the points,

$(x_1, y_1) = (1, 6500)\\\\(x_2, y_2) = (5, 17500)$

Therefore, rate of change is given as:

$m = \frac{17500-6500}{5-1}\\\\m = \frac{11000}{4}\\\\m = 2750$

Thus rate of change of profit for this period = $2750 per month

What is the GRM for a residential duplex with a selling price of $234,000 if the monthly rent for each unit is $925? A. l.054 B.

stiks02 [169]

Answer:

126.5

Step-by-step explanation:

Given :The monthly rent for each unit is $925

To Find : What is the GRM for a residential duplex with a selling price of $234,000 if the monthly rent for each unit is $925?

Solution:

Annual Gross Rents = $925

Property Value = $234,000

For answer to be 126.5 , $925 must be semiannual rent

So, annual rent = 925*2

Formula : Property Value = Annual Gross Rents X Gross Rent Multiplier (GRM)

Substitute the values :

$234000=925 \times \text{Gross Rent Multiplier}$

$\frac{234000}{925 \times 2}= \text{Gross Rent Multiplier}$

$126.5 = \text{Gross Rent Multiplier}$

Hence The GRM for a residential duplex with a selling price of $234,000 if the monthly rent for each unit is $925 is 126.5

So, Option D is true .
