Hi,

I assume the forward slash meant it as a fraction VS it being a division symbol. To answer your question, the remainder is 10.

Hope this helps.

Elena L [17]

Answer: $1,842

Step-by-step explanation:

John wants to earn 25% of his investment of $50,000 which is:

= $12,500

He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:

= Expenses + Return

= 9,600 + 12,500

= $22,100

Rent per month is:

= 22,100 / 12

= $1,842

If A is the area of a circle with radius r and the circle expands as time passes, find dA/dt in terms of dx/dt

valina [46]

The area of a circle in terms of the circle's radius $r$ is

$A=\pi r^2$

Differentiating both sides with respect to $t$ , you get

$\dfrac{\mathrm dA}{\mathrm dt}=2\pi r\dfrac{\mathrm dr}{\mathrm dt}$

Solve the following quadratic by<br> completing the square.<br> y = x2 - 6x + 7

kobusy [5.1K]

Answer:

x = 5 or x = 1

Step-by-step explanation:

x² - 6x + 7 = 0

x² - 6x = -7

x² - 6x + 9 = -7 + 9 1/2 of the x term than square it and add it the both sides.

(x - 3)(x - 3) = 2

( x -3)² = 2

$\sqrt{(x - 3)^2$ = $\sqrt{2}$

(x - 3) = ± 2

x - 3 = 2 or x - 3 = -2

x = 5 or x = 1
