A school district purchases a high-volume printer, copier, and scanner for $27,000. After 10 years, the equipment will have to b

e replaced. Its value at that time is expected to be $2000. Write a linear equation giving the value V of the equipment during the 10 years it will be in use. (Let t be the number of years after purchase.)

Answer:

V = 27000 - 2500t

Step-by-step explanation:

Let the linear equation that represents the value of the equipment after t years,

V = a - bt

Since, the original value of the equipment is $27,000,

That is, if t = 0, V = 27,000

27,000 = a - b(0)

⇒ a = 27,000

If t = 10, V = 2,000

2000 = a - 10b

2000 = 27,000 - 10b

10b = 25000

⇒ b = 2,500

Hence, the linear function that shows the value of the equipment after t years,

V = 27000 - 2500t

If bob makes 40 mintues of long distance call for the month, which plan cost more
lora16 [44]

First, look at the x axis (this is the one labeled Minutes Used per month)

Find the number 40, then look at where the lines meet on that line. The red line for Plan B it’s at 8 dollars. The blue line for Plan A is at 4 dollars.

Plan B costs more.

To find the difference, subtract 4 from 8.

$8 - $4 = $4

Plan B costs 4 dollars more than Plan A.

If you have any further questions feel free to ask.

Hope this helps.

Select interior, exterior, or on the circle (x - 5) 2 + (y + 3) 2 = 25 for the following point. (2, 3)
lozanna [386]
Standard equation of a circle: <em>(x-h)² + (y-k)² = r²</em> where <em>(h, k)</em> is the center and <em>r </em>is the radius. In the case of our equation here, <em>(x-5)² + (y+3)² = 25</em>, we can conclude that our circle has a center at (5, -3) and a radius of 5 units.

We can use the distance formula with the center (5, -3) and our point (2, 3) to see how far away they are...if the distance between them is less than the radius of the circle, it is on the interior. If it's equal, it's on the circle. If it's greater, it's on the exterior.

Distance = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Distance = \sqrt{(-3-3)^2+(5-2)^2}

Distance = \sqrt{(-6)^2+3^2}

Distance = \sqrt{36+9}

Distance = \sqrt{45}\approx6.7082

6.7082>5,\ so\ (2,3)\ is\ on\ the\ \boxed{exterior}

5. A piece of plywood has a length that is 5 more than twice its width. Write the expression that represents the area of the ply
Sholpan [36]
5w^2 = A
 
You would multiply the width (w) by 5 because it's 5 times more than twice it's width. Then w (Width) would be to the power of 2 because it's 5 times more than twice its width. And this will all equal the Area (a)
